I am simulating a multiphase fluid, and would like to volume render the concentration of two different fields simultaneously.
I have imported two different concentration fields into paraview and rendered both of them, however I find that the depth integration isn’t correct. One field always obscures the other, regardless of opacity and occlusion. Here are example plots from two different angles. You can see the blue phase is obscuring the red phase despite being behind it.
Is it possible to volume render multiple dataset simultaneously with correct occlusion? Or can paraview only correctly volume render with a single field?
This has been noted before, however I don’t think there were any fixes proposed.
If you want to volume render 2 overlapping volumes, try turning on the Enable Ray Tracing option under the View portion of the Properties panel. This will turn on the OSPRay raycaster. OSPRay seems to behave well when volume rendering overlapping volumes whereas the standard render does not.
