Re: [osg-users] ODE Trimesh with OSG ?
Hello Carlos! We use a TriangleRecorder (it's a NodeVisitor) and applies that to our terrain nodetree. It records vertices and triangles on all drawables. We then memcpy those into ode::dVector3[numVertices] (vertices) and int[3*numTriangles] (triangles). Then run dGeomTriMeshDataBuildSimple( and dCreateTriMesh unfortunately a cannot publish any code. I once had a plan to implement this better in my spare time but haven't got around to it yet. Yuo might watn to look at Delta3d since I know that they integrate ode with osg. I haven't looked at ode code in Delta3d myself but I'm sure it fine. Also: * the above simple description doesn't mention dynamic(paged) terrain so you may need to think about that. * Some of the terrains we have tried have been simplified, i.e. some trianles are very large, and ode seems to have problems with that. hope this helps Mattias On 8/18/08, Carlos Sanches [EMAIL PROTECTED] wrote: Hi!

Re: [osg-users] Confused about Uniforms and StateSets.
Hi again,
i tried using vertex attributes like this:
void PartialTreesDrawable::drawImplementation(osg::RenderInfo
renderInfo) const {
const osg::Drawable::Extensions* extensions =
osg::Geometry::getExtensions(renderInfo.getContextID(),true);
if ( extensions _drawable.valid() _speedTrees.valid()
!_speedTrees-_trees.empty() ) {
Speedtrees::Trees trees = _speedTrees-_trees;
Speedtrees::Trees::iterator it;
for ( it = trees.begin(); it != trees.end(); ++it ) {
extensions-glMultiTexCoord3fv(GL_TEXTURE0+4,
it-_position.ptr() );
extensions-glMultiTexCoord4fv(GL_TEXTURE0+5,
it-_rotation.ptr() );
extensions-glMultiTexCoord1f(GL_TEXTURE0+6, it-_scale );
extensions-glMultiTexCoord1f(GL_TEXTURE0+7, it-_windOffset );
// draw the tree
_drawable-drawImplementation( renderInfo );
}
}
}
However it seems to run slower than the implementation using uniforms.
Any ideas? Is this the recommend way for uploading variables to the
shader?

Well perhaps you need to do some reading up on uniforms and GLSL and

In particular Speedtree uploads the

known as a fast tree rendering api.
This suggests that that uniforms they are varying aren't ones that can

For commonly varying values you should always use vertex attributes,
the graphics hardware and drivers are all optimized for handling
varying vertex attributes. Uniforms are very different from vertex
attributes, uniforms are akin to the parameters you set in glLight,
glTexGen etc, they are a state change.
It would be nice if uniforms do not affect stateset sorting or require
statestets at all. I don't know if that fits into the current
architecture, however osg should provide a mechanism for updating a
single uniform many times in the same frame.
The mechanism is via osg::StateSet, it fits with the granularity of
state that OpenGL and the hardware suits, so it's the right place for
them. However, the CPU cost is higher than I'd like, the loose
coupling between uniforms and programs makes the OSG pretty flexible,
but wiring up uniforms to they current active program is relatively
expensive - perhaps this could be improved, but it won't change the
fact that uniforms aren't meant to be treated like vertex attributes

Re: [osg-users] Confused about Uniforms and StateSets.
Hi Richard,
This is roughly the way I tackled the task with PrecipitationEffect,
although I don't go via extension structure, refactoring things to
avoid the extension function looks ups would help speed.
Another possible speed up would be to look into implementing the
instancing extension as for your particular task it is probably ideal.

2008-08-18 11:21 + [r8770] robert:
* From Sergey Leontyev, 1. In StyleManager when applying styles to
a Label element the code below runs in a infinite loop. The
reason for this is that nothing increments the Reader r in the
case when applying a style to label, so I advance the reader when
no match was found. ( To replicate the error apply style to any
label) replaced this: while(!r.eof())
if(_styles[style]-applyStyle(t, r)) inc = true; with this:
while(!r.eof()) { if(_styles[style]-applyStyle(t, r)) inc =
true; else r.advanceOverCurrentFieldOrBlock(); } I tested it and
it works well for me, I did not find any problems with it. 2.
Added style support for Canvas element, event though there is no
styles to apply yet. It is usefull for someone who inherits from
Canvas class to develop another element. If applyStyle(Canvas)
does not exist there is no way to apply style to the element that
inherited from Canvas element. Added virtual bool
applyStyle(Canvas). and in added call to apply style if the
Object is of type Canvas:
StyleManager::_applyStyleToObject(osg::Object* obj, const
std::string style) { ... else
if(!std::string(Canvas).compare(c)) return
_coerceAndApplyCanvas(obj,style,c);

* From Erik van Dekker, I made several modifications: * The cause
of my errors was that my OSG source directory path contains
spaces. To fix this issue I wrapped all paths with quotes, as
stated in doxygen documentation. * I also received some warning
messages about deprecated doxygen settings, which I fixed by
updating the doxygen file, i.e. running \u2018doxygen \u2013u
doxygen.cmake\u2018. By running this command deprecated doxygen
options are removed, some option comments have changed and quite
some options have been added (I kept their default settings
unless mentioned). * I was surprised to find that the doxygen
OUTPUT_DIRECTORY was set to
\u201c${OpenSceneGraph_SOURCE_DIR}/doc\u201d, which does not seem
appropriate for out of source builds; I changed this to
\u201c${OpenSceneGraph_BINARY_DIR}/doc\u201d. (On the other hand,
maybe a cmake selectable option should be given to the user?) *
Fixed two warnings I received about unexpected
end-of-list-markers in \u2018osg\AnimationPath and
\u2018osgUtil\CullVisitor due to excess trailing points in
comments. * Fixed a warning in osgWidget\StyleInterface due to an
#include directive (strangely) placed inside a namespace. * Fixed
a warning in osg\Camera due to the META_Object macro that
confused doxygen. Adding a semi-colon fixed this. * Removed
auto_Mainpage from the INCLUDE option, because I am positive that
this file does not belong there; It never generated useful
documentation anyway. * I added the OSG version number
environment variable to the PROJECT_NUMBER option so that the
version number is now shown on the main page of generated
documentation (e.g. index.html). * Changed option FULL_PATH_NAMES
to YES, but made sure STRIP_FROM_PATH stripped the absolute path
until the include dir. This fixed an issue that created mangled
names for identical filenames in different directories. E.g.
osg/Export and osgDB/Export are now correctly named. * Changed
option SHOW_DIRECTORIES to yes, which is a case of preference I
guess.

Re: [osg-users] osgviewerQT shows garbage when viewer is destroyed and re-created
Qt 4.4 includes a QGraphicsView class, this class can be used to perform
OpenGL drawing,
instead of using the QGLWidget. This might open up some new possibilities
for
embedding osg in the QGraphicsView. I will take a look at the possibilities.

(i use qt 4.4.1 and osg 2.6, and adapted vierwerqt example sources)
The QOSGWidget works for me on linux.
On windows I got the pixelformat error but,
I got the QOSGWidget to work, and the --CompositeViewer version, by adding
the traits-setInheritedWindowPixelFormat = true; line.
I don't see any problems running a second time or multiple times.
I don't have any windows decorations by default, but these can also be set
on.
(it helps to set
viewerWindow-setGeometry(50,50,640,480); instead of
viewerWindow-setGeometry(0,0,640,480);)
to prevent the decorations from being outside the screen.
)
I did have problems when making the window heigth 0, but this was solved by
making the resize always a minumum of one pixel.
But i do get some errors in the console:
QWidget::repaint: Recursive repaint detected
and after closing:
Windows Error #6: [Screen #0]
GraphicsWindowWin32::makeCurrentImplementation() - Unable to set current
OpenGL rendering context. Reason: De ingang is ongeldig.
Windows Error #1400: [Screen #0]
GraphicsWindowWin32::unregisterWindowProcedure() - Unable to unregister
window procedure. Reason: Ongeldige vensteringang.
I am still not sure what solution to use, as the ViewerQT version does its
job, never had window problems with the AdapterWidget, but the performance
of the QOSGWidget seems better.
I also use a qtimer that triggers the update, but I want to start a new
(singleshot) timer only after the frame is drawn, to make sure every frame
is drawn before the timer issues a new frame. Large models seemed to have a
problem with the original code. would there be a better solution for the
update?

2008/5/7 Mathieu Champlon [EMAIL PROTECTED]
Hi Robert,
I quickly hacked the --QOSGWidget mode in order to work around the
invalid pixel format error (forcing traits-setInheritedWindowPixelFormat
= true;) and the result is the same : trashed scene on the second run.
I tried adding the piece of code you suggested but it does not change
anything.
By the way the crash you were experiencing running with --QOSGWidget is
actually due to osg::ArgumentParser modifying argv, thus on the second run
argc remains unchanged but all arguments have actually been eaten up from
argv.
I am now using this code to run the application twice :
int main( int argc, char **argv )
{
char** tmp = (char**)malloc( argc * sizeof( char*) );
memcpy( tmp, argv, argc * sizeof( char* ) );
run( argc, argv );
run( argc, tmp );
}

Hi Mathieu,
The error with -QOSGWidget looks to be a bug in this code, but its a
totally different path that the default path which uses
GraphicsWindowEmbedded to adapt the Viewer. QOSGWidget is the most
flexible path for integration and long term I'd like this to be the
default route under Qt. My own time is rather stretched out so I
can't address all these things at once.
The issues you are seeing with the default path is very unlikely to be
related to transparency, most likely is issues with display lists or
texture objects being reused inappropriately. In theory the viewer
should be release OpenGL objects when the context is destroyed, but
with GraphicsWindowEmbedded not all the standard functionality for
managing OpenGL objects is available, so perhaps this step is not
being executed appropriately.
One thing you could try is a
viewer-getSceneData()-releaseGLObjects();
osg::GLObjects::discardAllDeletedGLObjects(0);
In between the viewer allocations.

Re: [osg-users] FYI: OpenGL 3.0 Final Spec released
Hi Robert, Thanks for the putting up the notes, this is really useful - certainly far more concise and usable than the actual OGL spec! My pleasure. Might this be possible? I guess it's all down to the nesting of the conditional renderer tests... Thoughts? I admit most of what you said is a bit over my head, I haven't really looked into this from that point of view yet... I think with Larrabee on the horizon too (albeit still a ways off, as anyone who was at the article session will tell you it's all still a bit up in the air...) it opens up a lot of new horizons for optimizing cull/draw in new ways. We'll have to look at the specs in more detail, and I suspect we'll need a few prototypes before we can utilize these new resources to their full potential. In particular I think Larrabee, while not a total paradigm shift, opens up some interesting new avenues in rendering, which as opposed to a lot of other Siggraph ideas, can be used by the general audience / mainstream rendering. We're probably a little while off still though. P.S. If anyone is wondering to what I'm referring to when I say Larrabee seems up in the air: in the paper talk and in the Beyond Programmable Shading course, they were talking about it as if it were available now, but if anyone asked if it's an add-on board, or a co-processor on the motherboard, or how much it will cost, or when it will be available, or what are the details of such and such specific feature, they got the standard line of it's just a bunch of x86 processors or we can't comment on that, stay tuned. So to me, it looks like some specs on paper and not much more at this point. Looks interesting, but how far off is it? Who knows...

[osg-users] NVIDIA /ATI OpenGL support and tools
Hi all, I was at Siggraph last week, and I figured since I had access to all these NVIDIA and ATI people on the show floor, I should take the opportunity to talk to them about their OpenGL drivers and tools. Most of the high visibility people are the game developers who mostly use DirectX, so I wanted to make sure it was clear to them that OpenGL was also widely used. So I put on my best frequent poster on the OSG mailing list face, starting by saying that OSG is used by a large number of big companies in the simulation biz, some game engines, has over 2000 people on the mailing list which means over 2000 companies use it, etc. On the ATI side, they had a machine running a flight sim (I think it was FlightGear) on Linux with 4 monitors. I spoke briefly to one of the Linux driver devs who assured me they are making great strides towards getting better Linux drivers out there. (of course they're going to say that, but at least he knew what OSG was, which is reassuring) On the NVIDIA side, I spoke to one of the Developer Relations guys, as well as two tools developers. I was primarily trying to see if they would have interest in porting NVPerfHUD to OpenGL, as it's pretty much the coolest tool I've seen to diagnose graphics pipeline bottlenecks, and it's free, but only supports DirectX right now. I don't know if I actually got through, though, but at least they listened and seemed to agree with my opinions. The other thing I wanted to discuss was related to driver bugs. Both sides told me they get all bug reports but obviously can't reply to all of them. On the NVIDIA side, they told me the best address to mail is [EMAIL PROTECTED], which is a mail list and goes to many people, but beware of the spam filter which can be aggressive. In both cases, though, they stated that gDebugger is an excellent tool on the OpenGL side. I'll probably evaluate it to see if it would be useful for us, but one thing I can see it being useful for is in showing us how to use most of the performance counters in both NVIDIA and ATI hardware. I think the StatsHandler could be improved to help a lot more in diagnosing bottlenecks, and in particular the counters for ATI hardware should be added... One thing that's reassuring (at least to me) is that both NVIDIA and ATI are on the OpenGL ARB, and both made strong commitments to OpenGL 3.0 support. I guess that's still PR, but I hope it will lead to better support for the near future. Anyways, I just wanted to report my endeavor and results, even though they're not very conclusive... I think if we're vocal and try to explain our way of thinking we'll eventually be heard. Unfortunately it seems to me that OpenGL support is still just a checkbox requirement on a list of requirements, and that the actual *quality* of the support doesn't matter that much, so I hope that will change by talking to these people when we have the chance to.

Re: [osg-users] Virtual Terrain Generation on Which Tool ?
Hi Ümit as I said OpenFlight(tm) in itself does not inherently support PagedLOD's, the format only directly supports LOD's That does not mean a PagedLOD system such as OSG or Train cannot use an OpenFlight(tm) file directly for a geometry leaf, OSG and VPB by default use IVE and OSG/IVE have direct support in them for PagedLODing With OpenFlight(tm) The pagedLODing/loading has to be handled by the Scenegraph and or Application and not by OpenFlight(tm) ( this is how Vega and Vega Prime work/ed ) Apart from OpenFlight(tm) not directly supporting PagedLOD's you typically don't want to use OpenFlight(tm) directly because of the load time, in the case of VegaPrime most users would convert the OpenFlight(tm) to VSB which would typically load between a factor 10 to 100 times faster, and thats why OSG has IVE files they load in a similar very fast time to VSB files as compared to OpenFlight(tm) files which load slowly due to the inhernat 3d model content Gordon __ Gordon Tomlinson Email : gtomlinson @ overwatch.textron.com From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ümit Uzun Sent: Monday, August 18, 2008 3:41 PM To: OpenSceneGraph Users Subject: Re: [osg-users] Virtual Terrain Generation on Which Tool ?

Then they collect the related terrain database and models database, so they show you whole cith of terrain :) If I understood wrong in this method, please look at the (http://www.triangraphics.de/index.php?1=Downloadl=eng) simple database in flt and osg and show me the right way. And I think Jean has a amazing instinct on this topic :) Thanks so much everyone. Ümit Uzun 2008/8/18 Jean-Sébastien Guay [EMAIL PROTECTED] Hi Gordon, Robert, Umit, FYI OpenFlight(tm) does not directly support PagedLOD OK, that's what I thought. So my suggestion to convert to both a Blender-readable format *and* .ive (with PagedLODs), use the former to add features to the terrain, then save only the added features and load them in the final app with the .ive PagedLOD terrain would make sense. Thanks for confirming what I instinctively thought. :-) J-S -- __ Jean-Sebastien Guay[EMAIL PROTECTED] http://www.cm-labs.com/ http://whitestar02.webhop.org/ ___ 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] Fog and desired usage
Hi, I just had a couple of questions about the desired usage of the fog state attribute. 1) What does it mean to have different fog states on different branches of the scene graph? Would this have any effect? 2) Is the desired usage to set the fog attribute on the root node? Thanks, Brett ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] RTT RenderBuffers
When rendering to a texture, what determines the RenderBuffer (internal)
format? I would have thought it should use the texture's internal format to
define the RenderBuffer format, but I don't see this in the code. However, I do
see this in FrameBufferAttachment::FrameBufferAttachment(Camera::Attachment
attachment) when given an image pointer attachment:
osg::Image* image = attachment._image.get();
if (image)
{
if (image-s()0 image-t()0)
{
GLenum format = attachment._image-getInternalTextureFormat();
if (format == 0)
format = attachment._internalFormat;
_ximpl = new Pimpl(Pimpl::RENDERBUFFER);
_ximpl-renderbufferTarget = new osg::RenderBuffer(image-s(),
image-t(), format);
}
else
{
osg::notify(osg::WARN)Error:
FrameBufferAttachment::FrameBufferAttachment(Camera::Attachment) passed an
empty osg::Image, image must be allocated first.std::endl;
}
return;
}
Do I have to set the internal format manually by calling the Camera-attach
twice:
camera-attach(osg::Camera::COLOR_BUFFER, texture, 0, 0, false, samples,
colorSamples);
camera-attach(osg::Camera::COLOR_BUFFER, GL_LUMINANCE32F_ARB);
I don't see in the code where the camera ::Attachment._internalFormat is being
initialized when given a texture.
Am I missing something? Is there a better example of this than the
osgprerender.cpp example?

[osg-users] externally created Framebuffer object.
I have an external library that wants to create a frame buffer object into which I render something using osg, then it will do post-processing on it. I have a specific camera that I want to have render into that buffer, but I can't seem to find any way that I can assign an externally created frame buffer object to a camera. I can hack it by having it create the buffer in a pre-draw callback, but if I try to do any rendering with an nested camera, OSG clearly can't set the state back correctly, plus I get OpenGL errors even if it works when it tries to set the draw and read buffers. I looked at the render stage, on which I can set a frame buffer object, but creating a renderstage for a camera is rather convoluted with the render stage cache on the camera, and it looks like the api doesn't really want me to do that. Even if that problem is solved, I can't give the osg::FrameBufferObject an id to use, it wants to create its own buffer. Is there any way I can solve this? I would like to avoid modifying osg if I can. If I can't, do you have an suggestions on how I should change it?

You need an EventHandler and a osg::Timer. Set the color in EventHandler::handle(osgGA::FRAME). There is probably 10 other ways to do this also.

Re: [osg-users] plugin ttf
Hi all, Enough of these posts already :) I compiled the bulk of the dependencies with msvc90 Express this weekend using Mike Weiblen's build scripts. Could I zip those and put them on the web site? I've asked Mike off list to put them on his site(or even a branch in his svn) but I guess he's out-of-office. The demand for these won't go down until msvc10 I think so we might try to take this load off the list. Suggestions?

[osg-users] osgShadow and Stereo
Hi, I was wondering if there are any known problems with using osgShadow with a stereo setup. I'm using a Quadro with stereo enabled, but the osgShadow example crashes, as does my own code that uses shadows. The other OSG examples run fine, and my code works if I comment out the shadowing. As a quick first attempt at solving this problem I thought I'd check if this is a known issue.

Re: [osg-users] NVIDIA /ATI OpenGL support and tools
Hi Paul, Unfortunately it seems to me that OpenGL support is still just a checkbox requirement on a list of requirements, and that the actual *quality* of the support doesn't matter that much, so I hope that will change by talking to these people when we have the chance to. The hardware vendors on the ARB, not just ATI and NVIDIA, but also Intel and others, have a commitment to OpenGL that goes much further than considering it a 'checkbox requirement. Pertaining to quality specifically, the lack of an up-to-date OpenGL conformance test suite is an issue that is of great concern to the OpenGL ARB. Funding is typically cited as one reason for why the conformance tests aren't brought up to date. I'll preface by saying that I don't want to start a flame war here, just talking from my point of view. What you say above might be the intention, but in ATI's case at least, that's not what I see in reality. They seem to think their driver support is fine (at least the guy I spoke to) but it falls short in many areas. Good point about the conformance tests though. These will be key to getting good quality driver support in the future, and it's a great thing that they're bringing them back up to date and putting more focus on them.

As a quick first attempt at solving this problem I thought I'd check if this is a known issue. I've used osgShadow::ShadowMap with anaglyph stereo without problems in the past. However, not having a Quadro card myself, I've never used it with a quad-buffer setup (which I assume is what you're trying to use? you didn't specify, you just said stereo). I'll have to defer to others as to whether that normally works or not. You might want to specify which version of the OSG you are using though.

Re: [osg-users] update callback versus drawcallback
You could query OpenGL during the draw traversal, note the result, then modify the scene graph during the subsequent update traversal (if you can accept the 1-frame latency). Note that while you have a single update traversal per frame, you could have potentially multiple draw traversals per frame, each with different contexts. Querying each context could, potentially, yield different results. To be robust, your code will need to operate in such heterogeneous environments. You might look at OcclusionQueryNode for an example, though it's somewhat complex.

My question is, how does one add openGL context-sensitive hierarchy to an existing scenegraph at runtime? For example, lets say based on a keypress, I want to query some openGL extentions, create some vertex buffers, build a little scene graph, and add this to the scene root. What is the best practice for doing this? Thanks for any insight!
