Re: [osg-users] Highlighting with OSG
Hi Daniel Ulrich presented a nice outlining technique on his homepage: http://www.sandbox.de/osg/ Richard -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Daniel Moos Sent: Sunday, October 07, 2007 1:52 PM To: osg-users@lists.openscenegraph.org Subject: [osg-users] Highlighting with OSG Hi @all I'm new here and I try to make a simple hightlighting effect with OpenSceneGraph. I want to highlight triangles, vertexes and lines from a loaded model by picking it with the mouse. The picking isn't the problem. But how can I make a highlighting effect? For example change the color of the object... A second Question... If I loaded a model into my scene. Where can I get a list with all the triangles and its vertexes? Thank you!

[osg-users] VPB with tiled raw data
Hi @ all, Is it possible to build a paged database with VirtualPlanetBuilder from heightfield and texture data that is tiled ?? More precise, can VPB process multiple import data files to build a whole representation of the area. What happens, if heightfiled or texture data tiles: - overlap - do not fit exactly (space between tiles with no data) - have not the same resolution What happens if the heightfield data and the texture overlap not perfectly (e.g. larger extend of texture than of heightfield or vice versa) ?? Is it possible to have more accurate heightfield data embedded into more general one (e.g. a precise representation of an area of interest on a whole globe) ?? Does the more general height data then cut through the precise data and it ends up with very ugly artifacts?? Thank you for consideration Christoph ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] frame rate locking, gpu stalling problem
Hmmm, while this does stop it from locking, the underlying problem seems to be the gpu taking up a ton of time. I've tested 2.2 and 1.2 glsl_mandelbrot.osg (1.2 was fine last I used it), now they both take up alot of gpu time (80ms per frame), so I'm not sure what could be causing this. Installed the latest drivers for my card, but it didn't help, not sure what else could've changed that would cause this. May just reinstall the OS and start fresh if I can't figure out whats going on, any ideas would be appreciated though. --- Alberto Luaces [EMAIL PROTECTED] wrote: El Sunday 07 October 2007 03:09:55 idontgot aname escribió: It seems that as I zoom in/out, the framerate stays locked at a certain range until it can't handle it anymore. 60fps zoomed out, down to 30fps, down to 20/15/10 etc. and the gpu time goes up because of this. Does anyone know why the framerate would stay fixed at those ranges? Hi, this is a matter of synchronization with the screen refresh. Note that 20/15/10 fps are divisors of 60. If you are rendering at 60 fps and you draw the frame too late, you have to wait for the next refresh, so your framerate will go down to 30 fps. If you draw slower, the frame have to wait until the next refresh signal, so the framerate will drop to 20, then 10, then 6... until 1/0 fps. For experimental purposes only, you can deactivate the vertical synchronization in your driver options and see how these ranges disappear. Note that this is not recommended because it lessens the image quality (tearing artifacts may appear).

[osg-users] Problems when rendering to a FBO texture and using that as a texture.
Hi!, We have migrated all the code to the new osgViewer and everything is working marvelously, but: In OSG-2.2, with an Nvidia 7800 GT, I create an FBO to render the scene to a texture, this works correctly, but later if I want to use that texture as an input I get the following error: PixelBufferWin32::wglBindTexImageARB(), failed This used to work while working with osgProducer, but right now I dont know what can be wrong. Here is some code: //Render the current scene to a texture. camera-setRenderOrder(osg::CameraNode::PRE_RENDER); camera-setRenderTargetImplementation(osg::CameraNode::FRAME_BUFFER_OBJECT); camera-attach(osg::CameraNode::COLOR_BUFFER, _texture_fbo); camera-addChild(*_total_root*); _root_camera_fbo-addChild(camera); _root_camera_fbo-addChild(nested_quad_from_camera); viewer.setSceneData(_root_camera_fbo); //Then in another part of the code I do: osg::Texture2D* _imagen_fbo = getTextureFbo(); *_total_root*-addChild(group); group-getOrCreateStateset()-setTextureAttributeAndModes(0, _imagen_fbo,osg::StateAttribute::ON); //This last line provokes the warning. I belive I am doing something really really wrong like accesing the texture inside the same camera that renders it each frame... Please any comment would be very helpful.

Re: [osg-users] Problems when rendering to a FBO texture and using that as a texture.
Hi Alberto, The strange thing is OpenGL FrameBufferObject extension don't use the windowing-api so the wglBindTextureImageARB have not to be called. your code seem to be good. take a look to osgprerender example. osgprerender --fbo use frame buffer object.
