Summary0010995: Fixed point LOD tied to geometric LOD
DescriptionAs per ParaView 3.8 and earlier, the fixed point image volume renderer subsamples the number of rays cast into the data during an interactive render. I just noticed in my latest git head build that when I volume render the default wavelet source, the interactive rendering is relatively slow. It is always rendering at full resolution.

If I go to settings and move the LOD Threshold to its lowest setting (0MB), then the subsampled rays LOD works as expected. This is not an appropriate change in behavior. The LOD the count of traced rays is independent of the geometric LOD and should not depend on the size of the data being rendered.

This was done because we had a feature request from a user to interact with volume rendering without subsampled rays.

As a solution, we may want to expose a new setting on the View |Setting dialog to enable/disable subsampled rays for volume rendering when interacting.

Utkarsh believes he fixed this when doing his massive views work.

Verified it works, Mac standalone.
