Hi, This library is a great work for combing CUDA with OSG. I think osgCompute is just what I'm looking for. I'm trying to use osgCompute in a manner very similar to the example of osgComputeDemoApp which can be found in the forum. However, my project needs to bind DEPTH_BUFFER instead of COLOR_BUFFER to the render texture, and then use the rendered depth information in the CUDA kernel. Here comes a problem. As the formats related to the depth buffer (GL_DEPTH_COMPONENT, GL_DEPTH_COMPONENT24, GL_DEPTH_COMPONENT32, etc.) are not supported by CUDA, such error occurs: [osgCuda::TextureMemory::alloc()]: unable to register image object (cudaGraphicsGLRegisterImage()). Not all GL formats are supported. This problem troubles me a lot. So, how can I deliver the rendered depth information of the scene to the CUDA kernel by using osgCompute?
Thank you! Cheers, Jack ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=60769#60769 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
