Re: [osg-users] Issue on using pure OpenGL in custom drawables
Hi,
what are you viewing the output with? Maybe the automatic home position
calculation of osgviewer is making things blurry?

[EMAIL PROTECTED] wrote:
Hello,
first, sorry that i've opened this 2nd thread, but i got no access to my old
mails on work and the osg servers are still down ...
Yesterday I've tried to localize the issue on using pure OpenGL in my custom
drawables. To get more detailed informations I've scap down my complete test
environment to a single test drawable, where i use this single pure OpenGL
render call to check what's going wrong:
void TestDrawable::drawImplementation(osg::RenderInfo renderInfo) const
{
std::coutin TestDRW draw implementationstd::endl;
glColor4f(1.0f, 1.0f, 1.0f, 1.0f);
glEnable(GL_POINT_SPRITE);
glTexEnvi(GL_POINT_SPRITE, GL_COORD_REPLACE, GL_TRUE);
glPointSize(2.0f);
glBegin(GL_POINTS);
glVertex3f(1.0f, 0.0f, 0.0f);
glEnd();
glDisable(GL_POINT_SPRITE);
}
On construction of this TestDrawable, i set only the use of DisplayLists to false, to get access on the drawImplementation method on each render call, nothing more, no magic. This drawable is only added to a simple geode wich is the single element of the scene graph... I got the same issues (x value on opposite side as expected) as I've described in my other thread.
What me confused is, that the point sprite is rendered correctly (on the right
side of the coordinate system with a positive x value*) if i add any reference
model to the scene (in my case a simple osg shape). If i remove the model, the
point sprite is rendered on the left side of the origin, independend if i use
glPush or not ...
I've checked several other osg sources which uses pure OpenGL calls (i.e.
osgSim::ImpostorSprite or osg::ShapeDrawable) and it seems to me that I've done
all correctly. Each reference source does the same ...
I would be verry appreciative if anyone could me push in the right direction
before I'm getting nuts...
Best regards,
Christian
P.S.: I've attached the single Testdrawable and my main class to show you more
details.
*(If the reference model is added to the scene graph i could also see that the point sprite is sometime culled in point of my view, but i thing this may be a problem with the actually hacked getBounds method of the drawable, which returns no valid bounding box.)

Re: [osg-users] Very simple Firefox-Plugin to display osg-files
Forgot to mention: - Check if the cURL plugin use some other side-by-side assemblies (such as VC8 non-SP1 for instance). Maybe you'll need to recompile it? - Also check on Vista if you can, because Vista simply pops-up an error (cannot load the executable) when correct side-by-side assemblies are not found (but I guess not for delay-loaded DLLs...?). - And finaly, try your plugin on a clean machine with no MSVC installed, and no redistribuables installed, if possible. And to be more precise: private side-by-side assemblies can sometimes NOT coexist (VC8 non-SP1 / VC8 SP1 for instance) since they would be in the same dir with the same name. However, they ensure your plugin will work even with no redistribuables installed, at the cost of some kB in the plugin installer. Hope you'll find how to make it work.

Re: [osg-users] Text at fixed position on screen
Hi, Dusten.
I've looked at the osgtext example, but I couldn't figure out one thing
(perhaps because I didn't know what to look for). There is one piece of text
that says: text-setFontResolution(10,10); // blocky but small texture
memory usage and it is displayed on the top left corner. No matter how much
I rotate the scene, it won't move (this text is one example). That's what I
wanted, so I have searched the code for the above mentioned string and I
found out that this text is created and set like this:
{
osgText::Text* text = new osgText::Text;
text-setFont(font);
text-setColor(fontSizeColor);
text-setCharacterSize(fontSizeCharacterSize);
text-setPosition(cursor);
// use text that uses 10 by 10 texels as a target resolution for
fonts.
text-setFontResolution(10,10); // blocky but small texture memory
usage
text-setText(text-setFontResolution(10,10); // blocky but small
texture memory usage);
geode-addDrawable(text);
}
Where:
osgText::Font* font = osgText::readFontFile(fonts/arial.ttf);
osg::Vec4 fontSizeColor(0.0f,1.0f,1.0f,1.0f);
float fontSizeCharacterSize = 30;
osg::Vec3 cursor = osg::Vec3(margin*2,windowHeight-margin*2,0.0f);
Strangely enough there was nothing concerning a mode that would make it
fixed at a certain position. I've tried some other attributes but the best I
can do is get the text to be always parallel to the screen, but ot fixed.
Can you give me another hint?
Thanks,

Re: [osg-users] osg firefox plugin alpha
I'm afraid I have no expertise with VisualStudio linking requirements, so I have to defer to others with that expertise for moulding our CMake build system and any 3rd party binaries for windows. I presume Lilinx has come across these same issue and resolve them somehow, so perhaps he might be able to provide some guidance/fixes to the CMake build/dependencies to get this working. Robert. I guess that Lilinx has used the CMake default-setting, which is to link against the runtime-libs dynamically.

Re: [osg-users] Problems regarding mouse events with osg 1.2
HI Francesco,
osgGA::GUIEventAdapter::LEFT_MOUSE_BUTTON isn't an event type, so you
can comparing two different types and not surprisingly getting the
wrong result.
Instead you should use the PUSH and RELEASE event types, within the
switch to find out when buttons are pressed or released, then within
each block check which button is pressed using event.getButton().
Once corrected your event handling code will work in OSG-1.x and OSG-2.x.

Others events, such asPUSH, works very well. In particular when i

It prints wrong results using the mouse.
Is this a known problem with 1.2 version? Or have i done some errors

The problem is that when I modify one... all the other nodes are modified too. So, is there any way to avoid that ? I've tried a lot of options with osgEXP from 3DS max... no way ! The only way is to visit the scenegraph to clone stateset ? Thanks.

Re: [osg-users] Problems linking against OSG on OS X Tiger (on a Power PC)
I haven't tried installing OSG from macports but I've had good results on OS X by installing cmake via macports and then compiling OSG from source.

Re: [osg-users] Mesh/Triangulation Examples?
Simon, For the geometry, I do this, more or less: osg::ref_ptrosg::Geometry geometry = new osg::Geometry(); osg::ref_ptrosg::Vec3Array vertices = new osg::Vec3Array;// unsized array of vertices vertices-push_back(osg::Vec3(x,y,z)); // etc, ... osg::ref_ptrosgUtil::DelaunayTriangulator dt = new osgUtil::DelaunayTriangulator(vertices.get()); dt-triangulate();// Generate the triangles geometry-setVertexArray(vertices.get()); geometry-addPrimitiveSet(dt-getTriangles()); and then add the colour array as per the osggeometry example. For colouring it in by z-value, I also use a texgen to set up texture coordinates; something like this osg::StateSet* stateset = getOrCreateStateSet(); stateset-setTextureAttributeAndModes(0, m_texture,osg::StateAttribute::ON); osg::ref_ptrosg::TexGen texgen = new osg::TexGen; texgen-setMode(osg::TexGen::OBJECT_LINEAR); texgen-setPlane(osg::TexGen::S,osg::Vec4(0.0f,0.0f,1,0)); stateset-setTextureAttributeAndModes(0,texgen.get(),osg::StateAttribute::ON); The m_texture is a texture containing a coloured bar image, with which your elevation will get shaded.

Re: [osg-users] Picking without using osg::Viewer
Hi Dusten,
Has anyone implemented a picking solution that uses OSG's selection
algorithm -without- utilizing viewer? I use sdl to handle window
management and input, and bullet for physics (which could be fine for
selecting objects in-scene later, but this it would be quite a hack to
use bullet for gui element picking). The osgpick example only shows how
to do picking through viewer, so are there any suggestions on how to
proceed?
osg::ref_ptrosgUtil::LineSegmentIntersector intersector =
new osgUtil::LineSegmentIntersector(
osgUtil::Intersector::WINDOW, x, y );
osgUtil::IntersectionVisitor iv(intersector.get());
iv.setTraversalMask(/* mask of what you want pickable */);
// Use your main camera here.
camera-accept(iv);
osgUtil::LineSegmentIntersector::Intersections::iterator it;
for (it = intersector-getIntersections().begin();
it != intersector-getIntersections().end();
++it)
{
// Do what you want with the intersections.
}
Hope this helps,

Hi, Dusten.
I've looked at the osgtext example, but I couldn't figure out one thing
(perhaps because I didn't know what to look for). There is one piece of text
that says: text-setFontResolution(10,10); // blocky but small texture
memory usage and it is displayed on the top left corner. No matter how much
I rotate the scene, it won't move (this text is one example). That's what I
wanted, so I have searched the code for the above mentioned string and I
found out that this text is created and set like this:
{
osgText::Text* text = new osgText::Text;
text-setFont(font);
text-setColor(fontSizeColor);
text-setCharacterSize(fontSizeCharacterSize);
text-setPosition(cursor);
// use text that uses 10 by 10 texels as a target resolution for
fonts.
text-setFontResolution(10,10); // blocky but small texture memory
usage
text-setText(text-setFontResolution(10,10); // blocky but small
texture memory usage);
geode-addDrawable(text);
}
Where:
osgText::Font* font = osgText::readFontFile(fonts/arial.ttf);
osg::Vec4 fontSizeColor(0.0f,1.0f,1.0f,1.0f);
float fontSizeCharacterSize = 30;
osg::Vec3 cursor = osg::Vec3(margin*2,windowHeight-margin*2,0.0f);
Strangely enough there was nothing concerning a mode that would make it
fixed at a certain position. I've tried some other attributes but the best I
can do is get the text to be always parallel to the screen, but ot fixed.
Can you give me another hint?

[osg-users] Problems regarding mouse events with osg 1.2
Hi all,
I have written an application based on osgart 1.0 (that uses
OpenScenegraph 1.2) and i'm trying to add mouse event support. To do
so i have written a class derived from osgGA::GUIEventHandler and
added the event Handler to the viewer.
The handle works but i have noted some problems with events
RIGHT_MOUSE_BUTTON and LEFT_MOUSE_BUTTON that don't work as i expect.
Others events, such asPUSH, works very well. In particular when i
launch the application the result is a wrong interpretation of the
events. I have understood this problem with the following simple code
in the handle()'s body:
int event = ea.getEventType();
switch(event)
{
case osgGA::GUIEventAdapter::LEFT_MOUSE_BUTTON:
printf(Evento PUSH generato\n);
break;
case osgGA::GUIEventAdapter::RIGHT_MOUSE_BUTTON:
printf(Evento RIGHT_MOUSE_BUTTON generato\n);
break;
}
It prints wrong results using the mouse.
Is this a known problem with 1.2 version? Or have i done some errors
using the library?

Hi Francesco,
It's been a while since I used OSG 1.x... so I can't answer you; but as
osgART's source is available, I suggest you to port it so that it uses OSG
2.6 or 2.7. The work would benefit all osgART users, and I guess this will not
be very hard to do. Well I didn't use osgART so this only can be an assumption.

switch(event)

break;

It prints wrong results using the mouse.
Is this a known problem with 1.2 version? Or have i done some errors

Re: [osg-users] Headlight
Hi Robert, osg::View by default has a head light so you could just use this, or if you wish to use a LightSource in the scene graph then use the LightSource::setReferenceFrame(osg::LightSource::ABSOLUTE_RF) to put the light source in eye coordinates. I cannot use osg::View's headlight because I need better control over when the headlight is used and when it's disabled, plus I'm using shaders and need to set specific state when that light gets enabled/disabled. The ABSOLUTE_RF tip was exactly what I was missing, works great. Thanks!

[osg-users] Is it time that we have a OpenSceneGraph/src/3rdPartyPlugins directory?
Hi All, Following on from my earlier topic of discussion on OSG packaging granularity and naming, and picking up on Andreas experiments with a Firefox plugin, and Cedric's further dev of the Blender Python scripts for exporting to .osg, and the other community activity on various plugins for others tools, I feel it's worth discussing how we go about coordinating and making it more accessible to end users. Right now we have various projects that use the developed out in the community that fit the role of plugins to other tools, like modelling applications to provide OSG exporters, and plugins to browsers. Most of the these projects will be maintained out in the community, may have their own project websites, may have a single contributors, or several, and may be dropped, then picked up by others further down the line, or just sit annexed out on the wiki. This situation isn't too much work for me as It means I don't need to spend time coordinating or maintaining these works, but... often it looks like such projects come and go in terms of support for latest versions of OSG, or latest versions of the 3rd party applications, so I'd guess for many OSG users/developers that aren't straight forward to pick up and use. One possible solution might be to bring maintenance and distribution of these 3rd party plugins directly into the core OpenSceneGraph distribution in the form of a collection of src/3rdPartyPlugins projects. Some of these might be compilable C++ code such as a Firefox plugin, while others might be just a collection of scripts that just need to be installed in a place that a modeller such as Blender can pick up on. Custom Cmake installer might work well for taking these built libs/scripts into the appropriate places, as well as detecting dependencies and only building/installing what you have supported on your platform. Another other solution would be see if we can coordinate the management and software/build and distribution so that a similar pattern is used by all the various 3rd party plugin projects - to make it easier to OSG users to navigate to, use and contribute to them. If we were to got the direct integration route, we'll have to be careful about how we manage the integration of the sources, testing and on-going development in such a way as not to increase my own workload. Strategies to mitigate this workload would be to prepare the bodies of work so that they fit seamlessly into the OSG build system/directories structure, so it's just a straight forward task of my pulling in the software, then once they are ready then integrate into core OSG, but not before this. One needn't have a perfected software before integration, but it would at least need to fit comfortably and non-intrusively into the OSG build. A way of doing this prep work would be for us to use the branches section of the OSG svn repository in similar way to how Jeremy and Cedric have been prepping osgWidget and osgAnimation. If you do have software that you feel is a candidate for being part of 3rdPartyPlugins collection then please outline what it is, what files go into it, how it's built, how it might fit into a CMake build system, what its portability and dependencies are. Another area I do wonder about is whether we'd be able to share some components of software between some of the 3rdPartyPlugins as well, I know that there is Python script for Blender for exporting .osg files right now, and that Maya supports Python, so I wonder if a .osg file build class could be written in Python that is shared between both plugins, and with each just using its own glue code that uses this builder class to do the OSG output.

[osg-users] The Collada plugin and transparency
A little while ago I said I would revisit the handling of transparency in the Collada plugin. To that I end I started a thread on the Collada forum asking for help interpreting the spec in this area. https://collada.org/public_forum/viewtopic.php?t=1210 Since tumbleweeds now appears to be blowing across that thread I, I thought I would try a different approach. I will attempt to set out a suggested mapping between a Collada FX Common profile effect containing a Blinn technique, and OpenGL fixed functionality, and then throw this open to comments/assistance in this forum. The blinn element schema looks like this xs:element name="blinn" xs:complexType xs:sequence xs:element name="emission" type="fx_common_color_or_texture_type" minOccurs="0" / xs:element name="ambient" type="fx_common_color_or_texture_type" minOccurs="0" / xs:element name="diffuse" type="fx_common_color_or_texture_type" minOccurs="0" / xs:element name="specular" type="fx_common_color_or_texture_type" minOccurs="0" / xs:element name="shininess" type="fx_common_float_or_param_type" minOccurs="0" / xs:element name="reflective" type="fx_common_color_or_texture_type" minOccurs="0" / xs:element name="reflectivity" type="fx_common_float_or_param_type" minOccurs="0" / xs:element name="transparent" type="fx_common_transparent_type" minOccurs="0" / xs:element name="transparency" type="fx_common_float_or_param_type" minOccurs="0" / xs:element name="index_of_refraction" type="fx_common_float_or_param_type" minOccurs="0" / /xs:sequence /xs:complexType /xs:element So Collada is giving us emission, ambient, diffuse, and specular elements which can be either a fixed colour or a variable colour acquired from a texture map. In the OpenGL pipeline the lighting calculations are done prior to the fragment shading. The only exception is the specular highlighting which we can optionally postponed until after the fragment shading phase. So I would suggest that the starting position is that any textures in the emission, ambient, and specular elements are ignored. If a texture exists in the diffuse element then a default value (probably white) can be applied as the fixed diffuse colour and the texture used to modulate (GL_MODULATE) the incoming fragment colour in the fixed function fragment shader. The common profile does not allow multiple techniques to used in an effect, i.e. no multitexturing. If the diffuse channel contains a texture and the shininess element is non zero then specular highlighting should be postponed. I cannot think of a way of handling the index_of_refraction. Has anyone got any thoughts on this? Reflective and reflectivity need further study. Anyone got any ideas? That leaves the thorny issues surrounding the transparent and transparency elements. This is what the Collada spec has to say about then in general terms. == Determining Transparency (Opacity) If either transparent or transparency exists then transparency rendering is activated, the renderer needs to turn on alpha blending mode, and the following equations define how to combine the two values. Use these equations to get the correct results based on the opaque setting of transparent, where fb is the frame buffer (that is, the image behind what is being rendered) and mat is the material color before the transparency calculation. In A_ONE opaque mode: result.r = fb.r * (1.0f - transparent.a * transparency) + mat.r * (transparent.a * transparency) result.g = fb.g * (1.0f - transparent.a * transparency) + mat.g * (transparent.a * transparency) result.b = fb.b * (1.0f - transparent.a * transparency) + mat.b * (transparent.a * transparency) result.a = fb.a * (1.0f - transparent.a * transparency) + mat.a * (transparent.a * transparency) In RGB_ZERO opaque mode: result.r = fb.r * (transparent.r * transparency) + mat.r * (1.0f -transparent.r * transparency) result.g = fb.g * (transparent.g * transparency) + mat.g * (1.0f -transparent.g * transparency) result.b = fb.b * (transparent.b * transparency) + mat.b * (1.0f -transparent.b * transparency) result.a = fb.a * (luminance(transparent.rgb) * transparency) + mat.a * (1.0f - luminance(transparent.rgb) * transparency) In A_ZERO opaque mode: result.r = fb.r * (transparent.a * transparency) + mat.r * (1.0f - transparent.a * transparency) result.g = fb.g * (transparent.a * transparency) + mat.g * (1.0f - transparent.a * transparency) result.b = fb.b * (transparent.a * transparency) + mat.b * (1.0f - transparent.a * transparency) result.a = fb.a * (transparent.a * transparency) + mat.a * (1.0f - transparent.a * transparency) In RGB_ONE opaque mode: result.r = fb.r * (1.0f - transparent.r * transparency) + mat.r * (transparent.r * transparency) result.g = fb.g * (1.0f - transparent.g * transparency) + mat.g * (transparent.g * transparency) result.b = fb.b * (1.0f - transparent.b * transparency) + mat.b * (transparent.b * transparency) result.a = fb.a *

Re: [osg-users] osg firefox plugin alpha
nice link :) I suppose it acts as a compatiblity layer as Qt or wxWidgets but for browsers, doesn't it? Hi Alberto, I think the sandboxing is the main difference here, so you are not allowed to use all system calls and write nasty applications. From the first link that Andreas has given (http://www.codeproject.com/KB/openGL/FirefoxOpenGL.aspx), I think that the biggest effort to port the plugin to other platforms would be to be able to create a valid OpenGL context. Maybe Firefox's Canvas 3D would do? It seems to be active again. https://labs.mozilla.com/forum/?CategoryID=9 Has anyone noticed that Google has published a quite interesting application called Native Client. http://code.google.com/p/nativeclient/ Thanks for the link. I've just looked through the NativeClient docs and mailing lists traffic and it looks like OpenGL isn't supported right now, and looking at the list traffic it might not be right around the corner in terms of supported features. Hi Roger, I'm a little puzzled here. I thought that Native Client would offer canvas that native application could draw on with OpenGL also? Doesn't that Quake-demo run on OpenGL? But your are right, this is very fresh project. Still somewhat interesting stuff.

Such a system gives you (Robert) the choice of maintaining this code or not, as you see fit, but ultimately it is up to the community that is using it and has the necessary dependencies. Another benefit is it allows OSG to continue to grow and develop new support functionality, while not burdening people using the traditional core OSG with having to find a bunch of dependencies for code that they ultimately will not use. The only conceivable downside (that I can think of) is that new users might attempt to use some code that has fallen into a state of disrepair, giving them a bad out-of-box experience. -Paul ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

If a component of the OSG does full in state of disrepair then such a component should be moved out of the core OSG into the deprecated section of the svn repository. I think the main motivation with integration into the core is to increase the likelihood that components will remain maintained across platforms. It's my motivation for raising this topic, as right now we have components that have a brief flurry of activity and usability but then these fall off the map because the lead developer moves on. With a project like the OSG that lives for a long period then this on/off usability just isn't good for active users of the OSG. Users need a set of sources and associated binary packages that they can pull down and know that they can get them working robustly without lots of build hassles or trawling the Internet for solutions/workarounds. I must add a qualification to whether a component deserves a place in the core OSG - it needs to be shown to be relevant to a good spread of users, and to be maintainable by a range of contributors. The same logic of inclusion needs to be applied to 3rd party plugins as NodeKits, as discussed in the thread on NodeKits and the OSG.

Re: [osg-users] MAC
Hi Robert, Too much time has lapsed to reconstruct my exact problems -- too much cursing instead of note taking back then. I started with Cmake 2.4.7 that we'd been using for Linux OSG builds. It was quickly obvious that version wouldn't do. I don't recall how I ended up with cmake 2.6.1 - it was probably the latest stable version when I grabbed it, but it was giving me problem after problem. Just lucky I guess. I later grabbed version 2.6.2 which I can build without a hitch and is what I ultimately used to build OSG. I guess the big problem for me was that the Dependencies page was and still is way behind the curve on what's required for building on Mac OSX. It says CMake 2.4 or later is prefered. On Mac specific page there's mention of grabbing the SVN version of Cmake for XCode considerations, but nothing more specific about a required cmake version. The Mac (OS X 10.5.2) has libcurl.4.dylib. I also had a problem building the curl plugin on an i386 Linux system with libcurl.2.0.2 . Other Linux systems here have libcurl.3.0.0 although I haven't built on any of these. -Don Robert Osfield wrote: Hi Don, Cmake should only build the curl plugin if it finds libcurl installed.

I don't know why you have to use X11 (Qt?) but that could be the cause of your problems.

Re: [osg-users] Is it time that we have a OpenSceneGraph/src/3rdPartyPlugins directory?
Robert Osfield ha scritto: Hi All, Following on from my earlier topic of discussion on OSG packaging granularity and naming, and picking up on Andreas experiments with a Firefox plugin, and Cedric's further dev of the Blender Python scripts for exporting to .osg, and the other community activity on various plugins for others tools, I feel it's worth discussing how we go about coordinating and making it more accessible to end users. Completely agree, integration with other sw like browser,scripting,modelling is important and one of the weakest point of OSG compared with other projects ( ie OGRE ) is the lack of coordinantion in add-ons and the sparceness of source. Right now we have various projects that use the developed out in the community that fit the role of plugins to other tools, like modelling applications to provide OSG exporters, and plugins to browsers. Most of the these projects will be maintained out in the community, may have their own project websites, may have a single contributors, or several, and may be dropped, then picked up by others further down the line, or just sit annexed out on the wiki. This situation isn't too much work for me as It means I don't need to spend time coordinating or maintaining these works, but... often it looks like such projects come and go in terms of support for latest versions of OSG, or latest versions of the 3rd party applications, so I'd guess for many OSG users/developers that aren't straight forward to pick up and use. Are you thinking of a sort of 'battery included' OSG, with dependency and addons? One possible solution might be to bring maintenance and distribution of these 3rd party plugins directly into the core OpenSceneGraph distribution in the form of a collection of src/3rdPartyPlugins projects. Some of these might be compilable C++ code such as a Firefox plugin, while others might be just a collection of scripts that just need to be installed in a place that a modeller such as Blender can pick up on. Custom Cmake installer might work well for taking these built libs/scripts into the appropriate places, as well as detecting dependencies and only building/installing what you have supported on your platform. Another other solution would be see if we can coordinate the management and software/build and distribution so that a similar pattern is used by all the various 3rd party plugin projects - to make it easier to OSG users to navigate to, use and contribute to them. The two could not be mutual exclusive: a project could first be mantained externally but adapted to the common layout and then, eventually integrated. I think providing tools and structure to help people to work on the same code would help, expcially during internediate state of development. As far as the repositories share a common layout and there is a simple script to grab the needed components and build, the user could not even perceive there are different repos behind. I have looked at distributed CVS like Bazaar or Mercurial and it seems to me they are more flexible in allowing different management patterns. Regarding CMake build, each project could have his own CMakefile, but could share with other all the macros nedeeded (custom Find etc..) For example the FindOSG and the macros used to detect build options, could be shared among all the projects using OSG. If we were to got the direct integration route, we'll have to be careful about how we manage the integration of the sources, testing and on-going development in such a way as not to increase my own workload. Strategies to mitigate this workload would be to prepare the bodies of work so that they fit seamlessly into the OSG build system/directories structure, so it's just a straight forward task of my pulling in the software, then once they are ready then integrate into core OSG, but not before this. One needn't have a perfected software before integration, but it would at least need to fit comfortably and non-intrusively into the OSG build. A way of doing this prep work would be for us to use the branches section of the OSG svn repository in similar way to how Jeremy and Cedric have been prepping osgWidget and osgAnimation. If you do have software that you feel is a candidate for being part of 3rdPartyPlugins collection then please outline what it is, what files go into it, how it's built, how it might fit into a CMake build system, what its portability and dependencies are.

You're welcome to start a new thread on this topic to so what others might recommend to helping cut your compile times. Robert. True enough, but I am only building the core of osg and the default plugins. None of the other components build as I don't configure them and I'm unlikely to ever use them. I'm not going to be using any of osgParticle/osgTerrain/osgWidget in the foreseeable future either (worse luck) If there are another bunch of core libs, eg. osgWidget I have to remember to disable them in cmake or they build as well. It's not too bad at the moment, but if we wind up with lots of 3rd party libs the cmake interface is a pain. But it also seems silly to have a core library which doesn't build by default, or you wonder why it's there. Unfortunately we 'doze uses have to build the debug and release builds so it all adds up. Perhaps the cmake could be split in 2, so there's one for the core (and a couple of examples) and another for the extras? That would work with visual studio projects but I don't know if that would work with linux build systems...

I see dependencies as an external issue, any 3rdPartyPlugins directory
would just provide source and Cmake files to find/specify the required
dependencies - in much the same way the present plugins do.
Providing links to/instructions for obtaining dependencies is
something we need to populate the wiki with, and if possible provide
binaries/links to binaries for most common of the dependencies.
I have looked at distributed CVS like Bazaar or Mercurial and it seems to me
they are more flexible in allowing different management patterns.
My hope for osgforge was that it would take us some way towards
providing an incubator with standard web interfaces (tracs) and svn
version control. So far it has taken off though. Other version
control system might help facilitate things, but only if we can keep
things consistent across the wider family of OSG add on projects.
Currently I' m working on our VirtualRome osg4web Firefox and IE Plugin.
We can for sure benefit from having more structured firefox example/support
Perhaps it might be possible for us to provide a WebPlugin base class
interface that backends are provide for IE/Firefox/webkit. We'd need
to look at the commonality between an existing IE plugin and similar
Firefox plugin to see how practical this would be. Could you publish
you work in form that it could be reviewed in this light?

I'm also using CMake for build basic dependencies (tiff,jpeg,png,zip,curl)
under windows as I still use VS7.
I understand that under Linux the dependencies are found in the system but
under windows this is not an option.
could this be of some interest?
Dependencies discussion would be best done in another thread.
Another project I wold like to be adopted is OSGSwig pythin wrapper
Again another worthy topic that deserves another thread... :-)
Very interesting, for VirtualRome project I had to use templates in php for
building osg files on the fly on a web-server.
Having something stable in python would had helped a lot
I guess you could write a .osg ascii output from a Python builder
class to a string/memory rather than to file and then re-direct this
be loaded by the browser plugin. I don't know if you are aware but
the .osg plugin has a mode psuedo loader built into that that parses
the .osg file directly from the filename passed into the plugin. You
just add .osgs to the string and then call readNodeFile(Geode{...
}.osgs). This might help with you usage model.

Re: [osg-users] Why does the mailing list remove spaces from the subject line?
This is well know problem, but not with mailman. See https://bugs.launchpad.net/mailman/+bug/265915 which you will notice is rejected as invalid. Mailman folds long subject lines with CRLFTAB replacing the first convenient space character, which is perfectly legal according to RFC2882. The real problem is with mail reading programs (MUAs) that strip these characters out for display thus concatenating the words in the subject line. Even worse some of them use the stripped out version in the subject lines of replies or forwards. As far as keeping threads together, this is not a problem for mailman or properly implemented threading programs that organise threads based on the content of the In-Reply-To: and References: headers not the subject line.

Another off topic It would nice if we could raise the money for a team, but I don't think one could do it out of donations. We are talking about need to raise $USD 50k to 100k a year to bring on dedicated staff, I can't image us pulling in this type of donation each year. For fixed such salary costs you need a regular income to pay it, which points to a subscriptions model. Support contracts would fit the requirement of regular income. I do have a few clients on professional support, but the number is high enough to employ other engineers, as it only a fraction of my yearly income - the bulk of my income is for bespoke development projects, but these don't directly fund general project admin but they effectively enable me volunteering me time on the unpaid aspect to project work. Such funding doesn't stretch to employing others. One could look to converting more commercial OSG users to pay for support, but we'd have to have a ten fold increase in the number of support contracts to pay for one engineer fulltime. Scaling funding is hard. What is more practical is leveraging a bit of time from a number of different osg users. This is effectively what we do right now, although not always as effectively and consistently as is desirable in terms of getting binaries and dependencies out regularly. Any further discussion about funding reallys needs to pulled into a separate thread.

But when the message echoed back to my inbox, a second space was missing, so the subject appears like so: [osg-users] Is it time that we haveaOpenSceneGraph/src/3rdPartyPlugins directory? This all looks fine in your mail client? I've attached both your original post and my reply. It will be interesting to see if the attached message subject lines look correct to you in your client. -Paul ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph. org ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-opensce negraph.org ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.or g ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] Funding
Hi all, hi Robert, As requested (and as expected), I start another thread about funding / hiring employees / an OSG staff. (Reference: http://lists.openscenegraph.org/pipermail/osg-users-openscenegraph.org/2008-December/020389.html ) Before I start answering Robert, I'd like to say building up an OSG team sounds *very* interesting for *all* OSG users since it would increase the quality and the power on various aspects, and increase the visibility, and finaly making OSG the unavoidable reference library for scene graph (and more). (Note: by visibility, I mean working on a marketing / advertisment aspect) I really trust OSG, especially knowing that it's actively developped/supported and that there is a strong community around it. The problem is: how can a team be set up? Thread is opened. It would nice if we could raise the money for a team, but I don't think one could do it out of donations. We are talking about need to raise $USD 50k to 100k a year to bring on dedicated staff, I can't image us pulling in this type of donation each year. That's true. But maybe donations could be a begining? I'm thinking about donations because it can bring the starter point of something bigger. And maybe a part-time job to help you could do it at first? I'll send another mail about donations: I'll make a kind of poll to try to know how much money the community can bring to the project. That would be interesting and give you some clues about the fact that building a team is possible or not from donations. For fixed such salary costs you need a regular income to pay it, which points to a subscriptions model. Support contracts would fit the requirement of regular income [...] Well, I'm not really in favor of a subscriptions model, but it depends on how it is made. A very important point for me is that the community must *not* be weakened: I strongly disagree to kidnap the whole community and say hello folks! It's time to pay!, even if that happens elsewhere. However, there can be subscriptions and support contracts that don't weaken the community. I don't have much ideas at this moment, but that could be things like: - Subscriptions to an IM/voice support. - Consulting/expertise (well, as you already do I suppose). - On-demand tailor-made binaries generation. - On-demand tailor-made OSG extensions/customisations. - [Put your ideas here]. All of these require a team to work. So I guess that it will not be possible before step 2 or 3 of an OSG development plan. Again, that points to step 1: donations. Creating a team surely requires to be done step by step. What is more practical is leveraging a bit of time from a number of different osg users. This is effectively what we do right now, although not always as effectively and consistently as is desirable As I said before, the community is a (the?) great value of OSG. But maybe these generous volunteers have to be managed a bit by another volunteer? I mean a kind of admin that only tries to follow what has to be done, what is done, who does it... and so on. I guess this would not take much time. Maybe I can help on that point if you wish, since I'm not an OSG expert and thus not able to help on other points. To sum up: - Manage volunteers - Get money from donations - Hire someone (even a part-time job) - Do some marketing / advertisment (I have a few ideas on that too!) - Make more contracts and paid supports - Hire another guy - Begin to make systematic binaries builds, tests, 3rdParty maintenance and distribution... - Go ahead... Does that sounds possible/correct/logical to you?

In the most recent version of Xcode tools, the 10.4 version of libcurl is 7.13.1 and the 10.5 version is 7.16.3. I believe that OSG by default builds against the 10.4 SDK. Does that help?

Re: [osg-users] Funding
I few things I can think of: * Google summer of code is one way to get funding for an open source project. You will have to employ someone still studying, but I think that the mentoring project also gets some funds. * I remember reading on the website of damn small linux that they largely make their money from advertising. I don't like it, but they manage to get a consistent income from it. * Selling resource DVDs/blue-rays may also be an option. Maybe even external hard drives with big terrains on them? It's not a matter of making the product propriety, but downloading 20+ gig can be a problem for a lot of people. * Bounties can also be used. A user/developer would put a bounty on a feature that he/she does not have time to implement and whoever completes the feature gets the bounty. * Blender is selling a lot of merchandise. Not only tea shirts and mugs, but also printed books on blender and resource CD. I have also seen other people selling video tutorials, some of them was really impressive! * The linux kernel has an interesting model, there are a lot of developers and my guess is that most of them are paid, but not by a single entity. Funding for open source software is always a bit fuzzy. I think that a single source of income will never be able to employ a whole team.
