Hi,
i am trying to get OpenSG 2.0 running with CUDA 5.0 and Windows 7.
Compilation of the OSGContribCompute project worked fine (after i
uncommented the line
SET(${PROJECT_NAME}_DEP_TEST_INCDIR OSG_GLUT_INC_DIR)
in the CMakeLists.Lib.OSGContribCompute.txt, otherwise the GLUT functions
would not be found).
The testSimpleCudaComputeOSG can be started but as soon as the CUDA
execution branch is triggered, the application crashes at the call to
'cudaGLRegisterBufferObject' within the function
'updateGeoOSGCudaCallback' (Unhandled Access violation exception).
The CUDA programming guide specifies that before any CUDA interop call,
'cudaGLSetGLDevice' has to be called. So i added
cudaGLSetGLDevice(0);
after GLUT was initialized. I also replaced the function with
'cudaGraphicsGLRegisterBuffer' since 'cudaGLRegisterBufferObject' is
deprecated, but to no effect.
I set up a simple stand-alone CUDA application in Visual Studio 2010 that
calls this function without problems.
Any idea? Does anyone use CUDA and OpenSG?
Kind regards,
Alexander Lang
