j00ey Posted September 1, 2015 Share Posted September 1, 2015 I'm sure I've read about this before but I can't find any information about it at the moment. Can anyone tell me if it's possible to render a volume as if it were polygonal geometry? What I'd like to be able to do is use a density threshold and somehow ray march through the volume until hitting the threshold and at that point is the hard surface - much like converting an SDF or VDB to polys but at rendertime. Maybe I imagined that you could do it... Quote Link to comment Share on other sites More sharing options...
anim Posted September 1, 2015 Share Posted September 1, 2015 have a look at Examples/VolumeNoiseIso but essentially you are looking for vm_volumeiso property, which you need to add to your object or shader then vm_volumedensity will act like threshold value for iso surface Quote Link to comment Share on other sites More sharing options...
j00ey Posted September 1, 2015 Author Share Posted September 1, 2015 Brilliant, thanks for the pointer Tomas, I will investigate. Quote Link to comment Share on other sites More sharing options...
