CUDA and OpenCL

Dear All,

Does VTK uses CUDA or OpenCL (with CPU or GPU) for processing? Or can be enabled?

May I suppose that all massive processing is done in OpenGL?

VTK-m has some filters algorithms which use CUDA if enabled. Some raytracing may use CUDA as well, but I’m not sure which exactly. I don’t think there’s any OpenCL usage at all.

You can also implement image processing filters using GLSL using vtkOpenGLShaderComputation (in vtkAddon). See some more information in this topic.
