Dear Edge Team; I'm trying to build a simple volume rendering application on top of Cocoa in order to evaluate the GPU Ray Casting support, but when I run the application I've got the following error:
--- ERROR: In /Users/fauze/Development/toolkits/vtkedge/source/VolumeRendering/vtkKWEOpenGLGPUVolumeRayCastMapper.cxx, line 4139 vtkKWEOpenGLGPUVolumeRayCastMapper (0x768d600): Rendering failed because the following OpenGL extensions are required but not supported: Program received signal: “EXC_BAD_ACCESS”. --- I'm sure the program is ok since it works with the ordinary mappers of VTK and also if I let VTKEdge to load itself the mapper (vtkKWEVolumeMapper). The error occurs when I opt by vtkKWEGPUVolumeRayCastMapper which leads to the deployment of the vtkKWEOpenGLGPUVolumeRayCastMapper. The point is that the "following OpenGL extensions" are not listed and thus I can't figure out what is happening. Please, can someone give me so help? Some framework I'm missing? I'm running on top of Mac Pro Core i7 - NVidia GTX 285 - Snow Leopard / Leopard. Thanks in advance Fauze Ps.: The VTKEdgeVolumeRenderingCxxTests have printed out: Required extensions not supported.
