Re: [osg-users] please give your opinion on plugins reading from a virtual file system

I am already able to read any type of data from SQL databases with this system. But now I better understand what you want, it's true that the http protocol support is a sort of workaround specially made for it, it would be nice to make this system more general to be able to register any protocols (like FTP, SQL...). But currently you'll still be limited with the plugins implementing reading from a stream, to make it work for everyone, you'll need to make changes to the API and defer the file opening part into the core and only work with streams into the plugins. -- Serge Lages http://www.tharsis-software.com ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] shader or effect to show selected model
Color overlays are fairly simple. A one-line fragment shader: gl_FragColor = gl_Color * color_uniform; Where color_uniform is a vec4 uniform specifying RGBA color. This is the simplest of cases, of course. If you have other lighting or texturing going on, you would also need to account for that. Matthew W. Fuesz Software Engineer Asc.

I was in the same position this summer. Previously I'd used SDL for a
gamepad, but now needed to resurrect that code and redo it for a
wheel+pedals.
I looked at vrpn but failed to really grok it. In the same time it took
me to bash my head against the vrpn examples, I wrote the sdl code. The
following should be enough for you to do a quick test. SDL also supports
hats, and force-feedback was part of the Google Summer of Code, but I
haven't seen any results of that yet.

Re: [osg-users] DAE to OSG/IVE conversion problem when vertex are shared (OSG 2.4)
Hi Fabien, I suspect there is a couple of issues here. First up .ive doesn't support sharing of vertex arrays, it's not a particular common need which is probably why no one else has highlighted this requirement or step forward to implement. Adding won't be particularly difficult as sharing of Nodes, Drawables and State is already supported, but it'll require a increment of the ive version internal number/and careful handling of backwards compatibility. Same applies to .osg. Feel free to dive in and help implement it. The other issue is that your .dae model is just 3Mb while the output .ive is 250Mb, this screams to me that you have shared arrays in separate geometry, whereas your model really should be setup as a small number of geometry without shared arrays. I haven't had a chance to look at your model - I have a full inbox so am just skimming right now, but I'd suggest you have a look at how many primitives are in each geometry. Robert.

It seems the problem appear when vertex arrays are shared in the DAE model (in a mesh entity) between several geomerties using distinct materials. When the DAE file is loaded in OSG, it seems ok, it looks like everything remains shared. But when we write the node (to IVE or OSG for instance, but it seems it appears in other formats too), the shared vertex array seems duplicated for each geometry, including useless vertex : it dramatically increase the object size (from 3 Mb to 250 Mb in my example). Using osgconv --simplify 1, we remove useless vertex and the problem is almost solved. Regarding this problem, I'm wondering if there is something to improve in OGS : - To support shared vertex arrays (and normals/textures arrays..) between geodes in OSG or IVE format - To remove any useless array element when writing nodes See this example, http://spaceyes.nerim.net/sample/sample_dae.zip Thanks in advance for your answers, Fabien ___ 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-openscenegraph.org

Re: [osg-users] LineSegmentIntersector does not work with Billboards
Hi Judd,
I've just tried
osgpick lz.osg
And zooming into the trees and attempting picking is showing no
intersections results where I'd expect. Reviewing the relevent code
in IntersectionVisitor.cpp suggests that there is no special code for
handling the local model transforms that are required for billboards,
the so the answer is looks to be that even 2.6 hasn't had this problem
addressed. The relevant code is:
void IntersectionVisitor::apply(osg::Billboard billboard)
{
if (!enter(billboard)) return;
for(unsigned int i=0; ibillboard.getNumDrawables(); ++i)
{
intersect( billboard.getDrawable(i) );
}
leave();
}
Looking at the old IntersectVisitor.cpp code shows that it does have
some proper matrix code in there, which could probably copied across
into the IntersectionVisitor:
Robert.
void IntersectVisitor::apply(Billboard node)
{
if (!enterNode(node)) return;
// IntersectVisitor doesn't have getEyeLocal(), can we use
NodeVisitor::getEyePoint()?
const Vec3 eye_local = getEyePoint();
for(unsigned int i = 0; i node.getNumDrawables(); i++ )
{
const Vec3 pos = node.getPosition(i);
osg::ref_ptrRefMatrix billboard_matrix = new RefMatrix;
node.computeMatrix(*billboard_matrix,eye_local,pos);
pushMatrix(billboard_matrix.get(), osg::Transform::RELATIVE_RF);
intersect(*node.getDrawable(i));
popMatrix();
}
leaveNode();
}
Try merging this code in. If it works out just post the changes to
osg-submissions. Although it won't be in 2.6.0, this fix could
probably make it into later 2.6.x maintenance releases.
Robert.

Re: [osg-users] Creating a black object (strip everything, light, color)
Hi Sam, The OSG just passes data along to OpenGL so its usual to get a ground in how the OpenGL pipeline computes vertex colours using the lighting model/vertex colours, once you get your head around it you'll probably be able to pinpoint what is happening i..e why you are getting grey. You haven't really said enough about the setup of your scene graph for me to guess why myself though... What I can say though, is for a completely black object I'd just switch off lighting completely for these objects, and set there the geometries colour array to contain a black colour i.e. (0,0,0,1); Robert.

Re: [osg-users] FPS Motion Model
The problem is that through osg there is no way to get the raw mouse values. In normal mouse mode you can get the x, y and the delta values but once you move the mouse to the extent of the window we no longer get deltas even though we move the mouse. The quick and dirty solution is to recenter the mouse at 0,0 every time so that you can get the delta values. If there was a way to access the raw mouse values so that even though the extent of the window was hit and you would still get delta updates then there would not be an issue. If you have any ideas of how to build this type of motion model without having to warp the mouse pointer I would like to hear about them.

Re: [osg-users] Mouse motion models across multiple viewports
Hi Bob, osgViewer does try to cope with multiple camera/window configurations by projecting the local window coordinates into view coordinates - normally this is enough to ensure consistent mouse values on mulitpipe systems. For a dome it could get a bit more tricky, and it wouldn't certainly be easier if you did you use a joystick as it'd avoid any of the coordinate reprojection issues. I presume you have distortion correction in the mix as well. Robert.

Re: [osg-users] Render capability checking, is this a good way?
HI Viggo,
I'd suggest rather than have a high level loop, you just place the
tests for all levels right in side your myTestSupportOperationClass,
and then just query this after the realize to see what capabilities
you have.

Hi,
I need to automatically check the rendering capabilities of the current
hardware and chose rendering techniques from that. I want to find the best
practical way to do this.
I have looked into the OSGShaderTerrain example.
It uses a osg::GraphicsOperation class to do actual capability checking.
My application creates a osgViewer::CompositeViewer instance.
Basically this is the initialization in pseudocode:
viewer = new osgViewer::CompositeViewer();
view = new osgViewer::View;
viewer-addView( view );
view-setSceneData( myRootNode );
view-setUpViewInWindow( 100, 100, 1024, 768 );
viewer-run();
Now say that I have 3 different levels of rendering techniques:
2 = Complex
1 = Normal
0 = Simple
If I shall use the same method as done in the OSGShaderTerrain example, then
I would write the code like this:
level = 3
while( level-- )
{
viewer = new osgViewer::CompositeViewer();
capabilityChecker = new myTestSupportOperationClass( level ); //
myTestSupportOperationClass is a specialized version of
osg::GraphicsOperation.
viewer-setRealizeOperation( capabilityChecker );
view = new osgViewer::View;
viewer-addView( view );
view-setSceneData( myRootNode );
view-setUpViewInWindow( 100, 100, 1024, 768 );
viewer-realize();
if( !capabilityChecker-_supported )
{
..cleanup so we are ready to initialize again...
continue; // Check one lower level...
}
viewer-run();
break; // We did manage to run, so break the loop
}
I wonder if this is a good way to organize the capability testing?
Is there other ways I should explore?
QITODMWTAM-section (Questions I think OSG developers may want to ask me):
--
Q: What capabilities are you trying to check?
A:
I want to check if the current hardware can run shaders.
I would also check basic stuff like how many texture units I can use.
I would also check if I can render to an offscreen surface.
I plan to give each special-effect that I write a capability checking
function which I should be able to call from my specialization of the
osg::GraphicsOperation class. Each piece of code I have that require
checking will then be able to stop the system from using them if the
capability needs are not met.

Re: [osg-users] Has something changed regarding some of the plugin builds (the net plugin in particular) that might affect a Cygwin/Windows build
HI Brian, Good to hear things moving forward with Cygwin stability. As JS mentioned the net plugin has been deprecated, and just before 2.6 was moved out into the deprecated section of the OSG svn repository, alongside the original OpenFlight plugin, this means that the .net plugin isn't part of 2.6 nor svn trunk. Could you try OSG-2.6 out and see how you get on. Robert. On Fri, Aug 8, 2008 at 8:38 PM, Brian Keener [EMAIL PROTECTED] wrote: I have good news as far as Cygwin and OSG. Cygwin has been doing a lot of work on max file name lengths and the like and with a recent cvs update of Cygwin and a recent svn of OSG it appears the hangs at the termination of some of the examples has gone away. They appear to be closing normally now. I am not sure what else has changed but I had read some on Cygwin and socket use and found an article on their forums about mixing Windows winsock libs with Cygwin sockets which attempt to emulate unix sockets I believe and I will say right here I do not understand a lot about sockets but was beginning to wonder from what I read if this might be an issue. Actually I do believe that whether it be sockets or something else I do believe it may be that the hangs were related to something being mixed from the Windows world vs the Unix world since Cygwin sort of lives in both. That said I had commented the line in CMakeLists.txt that set OSG_SOCKET_LIB (wsock32) and that was when I realized that the examples were terminating normally and I realized that libs like the net plugin had not been built and the line I commented is even mentioned in CMakeLists.txt in relation to the net plugin so I assumed they were related. So to test a theory it was socket problem I put the line back and rebuilt - still no hang - examples terminate normal and still no net plugin - plus others. So now I wonder if something else change in OSG that would keep these from building or what setting(s) might have something to do with why they would not build. Sometimes I can't leave well enough alone - can't be glad it is fixed now I have to know how to break it again or what might have fixed it permanent. bk ___ 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-openscenegraph.org
[osg-users] Outlines using Stencil Buffer
Hello, This is my first post, so please forgive any breech of etiquette. I'm trying to use stencil buffers to achieve outlines around my objects, as described in the following article: http://www.codeproject.com/KB/openGL/Outline_Mode.aspx I want to be able to display the outlines of objects regardless of whether they are behind another object or not. For example, say I have two objects: A and B. If Object A is partially occluded by Object B, I want to display the entire outline of Object A, even the occluded part. The problem I'm running into is that when Object B is rendered first, the silhouette for Object B is in the stencil buffer, which prevents the outline surrounding the occluded parts of Object A from being drawn. Similarly, if Object A is rendered first, a part of the outline for Object B will not be drawn because the silhouette of Object A is in the stencil buffer. This is a long way of saying: How do I clear the stencil buffer in the middle of rendering? I took a look at osg::ClearNode, but when I set its clear mask to GL_STENCIL_BUFFER_BIT, it had an effect as if I had cleared the GL_COLOR_BUFFER_BIT instead. I am aware of the polygon offset method of outlining objects, but have found the stencil buffer method to be much more accurate in my application.

Re: [osg-users] VPB for osg 2.4
Hi again Yea, i just went over the latest release branch on delta3d, and it seams like they have indeed made the change to osg 2.6 ... Im so sry i didnt bother to do this first. My only apology is that there was a series of postings on the delta3d forum a while back surgesting that making the switch to 2.6 was not trivial. Sry Fortunatly it will allow me to stay with VPB head once i make the switch to newest delta. Btw i succesfully build a 640 Gig dataset using vpb -r914 on windows XP so its not impossible on windows :) Brgs. Ralf 2008/8/12 Robert Osfield [EMAIL PROTECTED] Hi Ralf, It should be straight forward to recompile Delta3D against OSG 2.6, while it's isn't binary compatible with OSG 2.4 the API is very close and shouldn't introduce any porting issues.

I could try building using the latest tagged VPB 0.9.7 with OSG 2.3.6 would a dataset created with this combination work with osg 2.4? Brgs.

I didn't tag a specific version of VPB for use with OSG. VPB is still in beta. I have to recommend using VPB svn trunk against OSG 2.6 for best stability. Im building on windowsXP using vpbmaster and it seams to start out fine but then stops loading the processors and uses a huge amount of memmory. It dosent really seam to stop again. This isn't really enough info to be able to guess what might be up.

Re: [osg-users] Has something changed regarding some of the plugin builds (the net plugin in particular) that might affect a Cygwin/Windows build
Robert Osfield wrote: As JS mentioned the net plugin has been deprecated, and just before 2.6 was moved out into the deprecated section of the OSG svn repository, alongside the original OpenFlight plugin, this means that the .net plugin isn't part of 2.6 nor svn trunk. Could you try OSG-2.6 out and see how you get on. I have been working from the current svn's and did not have curl installed on Cygwin but do now. Haven't had a chance to compare what plugins should be building vs what is but program that were hanging are now completing normal. Just have to work out a few debug vs release issues (at least in my mind issues) as far as when it uses the DEBUG_POSTFIX and when it shouldn't. bk ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] FPS Motion Model
Robert Osfield wrote: Hi Judd, The OSG just adapts the windowing systems provided mouse xy values, and as such is limited to the clapping that happens due to the windowing systems. Getting the delta moyse xy isn't supported, and personaly I don't know how one would go about getting this extra info from the various window systems, I'm open to suggestsions. The way we handled this is to provide wrapping of the mouse to the other side of the screen/window when the pointer gets within a few pixels of the edge. The pointer values are returned as normal (and reflect the change in position), but the delta values stay consistent (the pointer position is tracking internally and the extra movement from the warp is subtracted out). For us this provided nice, smooth delta values that we used to create an FPS motion model (among others). We just had to add a couple of extra functions to enable/disable the wrapping behavior (not everyone will want it), and we also had to implement grabbing of the pointer (restricting it to the window) for windowed applications, otherwise it was possible for the pointer to leave the window if you moved it fast enough. Unfortunately, none of this code was implemented in OSG, so I can't contribute it (and I'm not in a position where I can port it right now). Maybe the idea will work for someone, though. --J ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
