I have tried to display two volume rendered data sets simultaneously
with the image module. I coloured one using a red the other using a
green colour table and would like to overlay those to test for protein
colocalization. Each data set individually displays fine when wired into
the image module. However, when collecting both data sets into image
simultaneously, the resulting image is just black. This happens in
software rendering mode.
Hardware rendering mode doesn't seem to work properly anyway for volume
rendering on my box.
The documentation clearly (though obscurely) states that this is the
case. You cannot render coincident volumes in DX, never have been
able to on any platform. I think it's in the discussion of
"components", specifically, colors and opacities in the User's Guide.
Try Lloyd's links for other ideas, or use Isosurfaces which usually
make a more comprehensible object and support Perspective rendering
which helps enormously in my opinion for depth relationship
perception.
