Multi block volumes with gaps do not render correctly
When a multiblock image data is rendered with Volume representation, there is a visible glitch that appears to flip the ordering of the volumes every frame. To reproduce:
- Create Wavelet source.
- Apply.
- Create another Wavelet source.
- For the second wavelet, adjust the extent values for the x-axis. Choose values such that the wavelet does not overlap or touch the first wavelet. Ex: 40, 60
- Apply
- Create a Group DataSets filter.
- Select Wavelet1 and Wavelet2 using Ctrl + click and create a new GroupDatasets filter.
- Apply
- Change Representation to Volume and Color by RTData.
- Move mouse in the render view.
- See flicker.
Here's how the bug looks:
