Re: [osg-users] gDEBugger and OpenSceneGraph
Hi Paul, I tried gDEBugger releases from beta7 and experienced the same behaviour with OSG based applications in my Ubuntu (Linux - i386 libstdc++ 4.X) Breakpoints don't stop in the graphics context (I have to manually switch it every break) and what is worse, there is no information about OpenGL states at all.

[osg-users] Dummy Camera for taking a Screenshot
Hi all , I know this question has been asked again and again . But i am sorry i wasnt able to find the previous mails in the archive :( . What i want to do is when a user presses some key he should see some 3-4 screenshots of some specific nodes . So basically i am thinking of doing the following :- - Set up some dummy cameras - Bring them near the node ( at some distance ) - Take screenshots and write them in some directory - Load the images and use it as a texture to a plane - Display it to the user So what i did was i took a seperate viewer , and put the scene-data of the viewer to be the node .And then attached a slave camera to the viewer and took a screenshot . But it gave a black image as output .I tried doing frame() too , but that changed the window on which i was working on and also gave a black output. Can somebody help me out ?? And is there a way by which i can just use dummy cameras instead of dummy viewers to take a screenshot ? And how should i place the camera near the node ?

I have a large set of IVE models in my application and everytime when a model is going to be rendered the app freezes for a few sec to resize all textures to the power of 2. Is there anyway to get around it? The osgViewer::Viewer automatically runs a compile traversal on the first frame when an app is run, but this will only help if you set the scene data before the viewer is realized (as done in the osgviewer example.) If you are loaded your data after the window is realized you'll need to do a compile traversal after loading the data - the include/osgUtil/GLObjectsVisitor can be used for this purpose - but it must be called by the graphics thread for each window open, using an osg::Camera pre draw callback would probably be the easiest way to do this.

Re: [osg-users] running OSG in SLI mode
Hi, On Nov 28, 2007 1:44 AM, Loong Hin [EMAIL PROTECTED] wrote: I am running OSG in dual Nvidia 8800 GTS 320 MB graphics cards in SLI mode. But I notice there is not any improvement in update rate whether I am running in SLI or not. I wonder will OSG able to take advantages of SLI? Thanks. SLI is all down to the OpenGL driver doing stuff being the OSG's back, it doesn't have any control over it, its all driver settings controlled. Whether SLI is possible to enable depends upon the type of OpenGL features the application is using, you'll need to read up on NVidia docs for the limitations. As for potential performance benefits, its all depends upon what you bottleneck is, if its CPU then no amount of extra GPU power will help, its is a bandwidth/memory limitation then SLI could well make it worse, if its vertex process throughput then its again unlikely to make any difference, if you a fill limited/fragment shader limited then you might just see an improvement with using SLI. Frustratingly the OSG is well conditioned for multi-thread/multi-context usage, so can use multiple CPU cores and multiple GPU efficiently - more efficiently than SLI can in fact, but unfortunately NVidia haven't published APIs for controlling the compositing backend used by their SLI implementation, if they did we could tweak osgViewer to use the dual cards to output to one display, and we'd see much better scaling of performance than SLI typically offers. Alas Nvidia is too used to trying to make games appear a couple of fps faster by any hacks possible, rather than actually wanting to work with the developer community to solve the scalability problem properly...

[osg-users] OpenGL errors after applying attribute.
Apologies if this is a bit vague, but there may be a simple answer. I am running a class which uses a CompositeViewer and a setup with 2 monitors. If I run my scene with one window on one screen (either 0 or 1, it doesn't matter which) it works fine. However, if I add a second view (so there is a window on screen 0 and a window on screen 1) I get an error: Warning: detected OpenGL error 'invalid enumerant' after RenderBin::draw(,) If I then call camera-getGraphicsContext()-getState()-checkForGLErrors(osg::State::ONCE_PER_ATTRIBUTE) for both cameras this produces the errors Warning: detected OpenGL error 'invalid enumerant' after applying MyTex 0x8582ef1 repeated a few times MyTex is a class which inherits from Texture2D.

This works fine but now I need to render to a floating point texture and I have tried GL_FLOAT_R32_NV(which is the one I want), and some of the ARB-variants but I guess im missing something because it does not work. The shader im using is simply trying to output pixels as red gl_FragColor.r = 1; but nothing seems to get rendered, the texture just stays black . For the first frame that is rendered i get the following detected OpenGL error: invalid enumeration after RenderBin::Draw and subsequent rendering calls gives the message: invalid operation after RenderBin::Draw I set the following texture 'attributes' texture-setWrap(osg::Texture::WRAP_S, osg::Texture::CLAMP); texture-setWrap(osg::Texture::WRAP_T, osg::Texture::CLAMP); texture-setFilter(osg::Texture::MIN_FILTER, osg::Texture::NEAREST); texture-setFilter(osg::Texture::MAG_FILTER, osg::Texture::NEAREST); texture-setInternalFormat(GL_FLOAT_R32_NV); texture-setShadowComparison(false); The texture is attached to the camera as osg::Camera::COLOR_BUFFER RenderTargetImplementation is set to FRAME_BUFFER_OBJECT Im using a Quadro fx 700 with support for the GL_NV_float_buffer.

Re: [osg-users] Curved line
Do I get nice curved lines when filling a Geometry with Vertices? It depends on how many vertices you use to approximate your curve. Use enough so that the individual line segment lengths approach a pixel width, and you'll have the illusion of a smooth curve, just like with GLU or OpenGL evaluators. As you use fewer vertices and longer segments, the illusion becomes increasingly less convincing (again, just like with GLU or OpenGL evaluators). It's a sampling problem. Does OSG support Bezier curves or something like that? As Robert said, no. You'll need to implement this yourself by adding the vertices to approximate your curve. The bottom line is that GLU isn't doing anything secret under the hood that you can't do in your own code. -Paul ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

It's also possible that the resizing is not the real bottleneck and it's just the apparent problem because it prints a message to the console... You'll then have to find the real bottleneck.

You're on the right track, but the matrix elements

These 3 rows are 3D unit vectors that
define the 3 orthogonal axises.

No, the last row is the origin of the matrix

Changing them results in translation, not rotation.

Re: [osg-users] CompositeViewer and MatrixManipulators
Hi Till Did you try to pass the window size to the manipulators? Depending on your window setup (the way you create your graphics context and your views) and the underlying windowing toolkit (native, Qt, wxWidgets, ...) there may be instances where the manipulators do not know the actual window size and simply do not compute the correct mouse movements. Use _view-getEventQueue()-windowResize(0, 0, width, height); to inform all interested parties of your resize. Of course, your parameters should account for the specific view position and size in your graphics context.
