I’m trying to view an image file (.vti) in wich each areas are identified by a unsigned int value (between 1 and 500 for instance). Unidentified areas have 0 as value.
When I use a volume representation of the data, i can’t clearly see areas identified by number 1 or 2 since I put opacity of 0 to 0.
At the contrary, if I put opacities of areas from 1 to 500 at 1, and interpolation is done between void area (0) and others → almost everything look the same :
I’m afraid this is a limitation of the Volume rendering representation.
Your dataset is perfectly adapted to the DigitalRocksPhysics plugin tools though. Using ExplodeMaterialCluster filter with a factor of 0 you can get this rendering:
Thanks a lot for your quick answer.
I didn’t know this plugin and it work very well for this kind of vizualisation.
Playing with ambient occlusion and tone mapping gave me something great !
