art3mis Posted July 8, 2017 Share Posted July 8, 2017 (edited) Hi Discovered this Blender add-on on github. In order to fix a collision problem with non convex geometry I need something similar for Houdini. Is anyone aware of an asset or OTL that does this? https://github.com/kmammou/v-hacd http://kmamou.blogspot.ca/2011/10/hacd-hierarchical-approximate-convex.html Edited July 8, 2017 by art3mis Quote Link to comment Share on other sites More sharing options...
vtrvtr Posted July 8, 2017 Share Posted July 8, 2017 Sorry if I'm missing something, but you can do this with the simple voronoi. Just break the pieces and glue then together or something of the sort Or you can use the vdb to spheres sop to fix the problem with concave geometry. On 16 it's even in the shelf called "RBD Sphere Objects" Quote Link to comment Share on other sites More sharing options...

mestela Posted July 9, 2017 Share Posted July 9, 2017 From what I remember, the main advantage of the other algorithm was the 'approximate' in the title. The algorithm gives you a margin of error for shape fitting, so it'll be maybe 95% accurate and made up of 4 clean large shapes, vs 100% accurate and made up of 50 smaller shapes. But as you say, the vdb sphere pack trick works pretty well! Quote Link to comment Share on other sites More sharing options...
