Hi, 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…

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: [image]

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 ! [image]

Woow nice visualization @schupin ! Love the way occlusion makes the data almost real

Looks really cool! Still, I would love to see “values as categories” being supported for volume data.
