Summary0013070: vtkFixedPointVolumeRayCastMapper and vtkSobelGradientMagnitudePass
DescriptionWe have a renderer with a volume added to it. On this renderer, we're trying to add and remove a Sobel pass (in the real world application, the user toggles a button, and depending on that, we either add or remove a Sobel pass to the renderer).

When we use a vtkFixedPointVolumeRayCastMapper, when applying the Sobel pass and then removing it, a black rectangle is left behind, corresponding to the screen-aligned bounds of the volume. This rectangle never goes away again on applying or removing any other render passes. Other volume mappers don't seem to have this problem. A screenshot, test application and test data are attached (but this happens with any data).

Use 'a' and 'd' in the test application to add or remove the Sobel pass.

There's an unrelated vtk warning display in the application, but I don't think this causes the problem; this happens with all volume mappers.
TagsNo tags attached.
