amination Posted March 19, 2013 Share Posted March 19, 2013 Hey Everyone! I was wondering if there are other ways to mesh point clouds in Houdini. I've tried meshing point cloud with metaballs and the results was very blobby, not as smooth as I was expecting. Although, pointCloudIso was not working at all. I would appreciate your help in advance. Thanks, Quote Link to comment Share on other sites More sharing options...
tjeeds Posted March 19, 2013 Share Posted March 19, 2013 Although, pointCloudIso was not working at all. I'm guessing you don't have a normal then, right? It ought to work if you can get it N. Quote Link to comment Share on other sites More sharing options...

rafaelfs Posted March 19, 2013 Share Posted March 19, 2013 The best solution I've ever seen: http://www.apileofgrains.nl/point-cloud-meshing-part-1/ Although I haven't tested, and the authors says it's not "complete"... maybe you can figure it out...? It's way over my head right now! cheers Quote Link to comment Share on other sites More sharing options...
amination Posted March 20, 2013 Author Share Posted March 20, 2013 Yes, the N were missing for PointCloudIso Sop, but even after normalizing I was still getting a blobby surface. I am actually working with an imported pcould in Houdini, and for some reason the ParticleFluidSurface SOP wasn't meshing the pcould and wasn't even getting an error either. Wow, that script seems to adds up a smooth triangulated skin over the Pcloud, thank you! I am looking deep into it. That actually seem to be the best solution by far.

cubiccube Posted March 21, 2013 Share Posted March 21, 2013 Have you tried meshing with the new VDB SOPs? Smooth SDF and Reshape SDF do a pretty excellent job of reducing blobbiness from pc generated SDFs, not to mention they're super fast.

amination Posted March 22, 2013 Author Share Posted March 22, 2013 I actually haven't tried VDB SOP yet, I read about it a bit and hear it is fast. I'm still using H12.1 though, but I just noticed there is a VDB toolkit out there for 12.1, which is a good news. But so far the particleFluidSurface Sop is doing the trick, slow, but doing the job I couldn't find some documentation based on VDB SOP, by any chance is there any link out there I can look at? and thanks for the tip!
