Hi Tobias, Greate would be to get a RayTracer attached to the OSG scene. With option to trace or not. Normally OSG won't trace, but if we like to get high quality screens, we can just turn on the tracing. But i was thinking about this still more then once. What we should get or what i like to integrate as soon as i have some hours to analyse the osg core, we should store the triangles, trianglesfan, ... (GL geometries) in a accelerated spatial data structure, best kd-Tree like data organisation. Even the intersection test could be boosted, also futures animations, collision checks and so on, boosting of depth sorting for transparency pre triangles should become possible. Also haptic-rendering could be an option for future application. This integration would be an essential topic.
I am not yet sure how we should change the osg internal data structure, at the moment we store vertices in simple arrays. I feel like to remap them into an kd-tree. then the whole scenegraph is organised in a spatial data structure. and the once we have a fast internal data representation, we may are really close to render the scene no longer as face rendering also ray casted, ray traced parts would be an futur options. what would be really greate. May we will get small parts raytraced, others not. what are others thinking about this topic. /Adegli 2007/10/2, Tobias Münch <[EMAIL PROTECTED]>: > > Hello to all OSG developers. > > Does anybody has developed a raytracer based on OSG or OpenGL which is > free to use on other applications?
