Sorry, my question is about how to compile VTK with OSPRay,
I have already checked Module_vtkRenderingOSPRay in cmake-gui and recompile VTK, but my program got error as:
Warning VTK is not linked to OSPRay so can not VolumeRender with it
What did I miss?
The error is fixed after I add below two lines:
vtkOSPRayPass* osprayPass = vtkOSPRayPass::New();
render->SetPass(vtkOSPRayPass);
thanks!
