Hi sholmes, Thanking you for your answers. Previously, I used osgCompute-1.1 and osgComputeDemoApp for my project. Now, taking your advice, I've check out the latest osgCompute from svn and I'm using the osgRTTDemo code as an example. However, I still can't map the depth texture to CUDA successfully. Such error still occurs: osgCompute::Memory::Object: "": allocation of memory failed My codes related to the depth texture are shown as follows:
Code: ...... rttTexture->setInternalFormat( GL_DEPTH_COMPONENT ); rttTexture->setSourceFormat( GL_DEPTH_COMPONENT ); rttTexture->setSourceType( GL_FLOAT ); ...... targetTexture->setInternalFormat( GL_DEPTH_COMPONENT ); targetTexture->setSourceFormat( GL_DEPTH_COMPONENT ); targetTexture->setSourceType( GL_FLOAT ); ...... rttCamera->attach(osg::Camera::DEPTH_BUFFER, rttTexture, 0, 0, false, 0, 0 ); ...... I'm successful in rending a depth texture but fails to pass that to a CUDA kernel. Could you send me your depth texture codes that you have run successfully with osgCompute? Thanks again!
