[vtkusers] Shadow support on volume rendering

Tue Oct 31 12:05:34 EDT 2017

The data I am using is straightforward 16 bit signed CT data, no unstructured
grids. I believe I saw that support for this had been added recently to
OSPRay. I have put the following code in to add the render pass
(rendererToAddTo is a vtkRenderer):

vtkSmartPointer<vtkOSPRayPass> osprayPass =
vtkSmartPointer<vtkOSPRayPass>::New();
rendererToAddTo->SetPass(osprayPass.GetPointer());

With this commented out, the volume renders fine with the GPU renderer, so I
am fairly sure the rest of the pipeline is ok.

With these lines in place, I get the same exception when the light array is
created. Unfortunately, I am testing this in an existing class hierarchy, so
giving you the pipeline code may be a bit tricky as the code is in various
places. The light is just the default one (follow camera?) that vtk adds
automatically.

I have managed to run the tests as you asked in your previous message and
all seems fine (rendered images appear) until the final two. These look to
'half render' an urn with a grey rectangle below. The output is as follows:
