Hi, I am using the voronoi split/fracture node on the default test pig head and finding that whatever settings I use I get a poor quality resulting surface. It has holes all over the place where the split faces don't properly sit together. How to I stop this happening? Here's what I am seeing:
Bonus question - is it possible to do a voronoi split without actually separating the pieces? ie the result I would get if I used a fuse after running voronoi split (without internal surfaces). I don't want to rely on fuse because I might fuse points that shouldn't be fused.
Looks to me like the voronoi split node can't handle non-planner faces. Pre-triangulating would be a workaround in some cases but it will mess up others and it would be great if it worked robustly for all good faces.
yes you are right this is not a clean solution. But you could use the divide sop before voronoi fracture - turn off or set Maximum Edges to 4 - turn on triangulate non planar, so the planar quads will not be divided. this would result in what i would expect. It keeps the good planar faces…
PS the pighead has almost no planar faces setting the Non-planar polygons value to a small value will not leave many faces untriangulated. So voronoi fracture actually does quite a good job… for the pighead i get almost 100% non planar at 0.001 for a torus i get 0% at 0.000001
Yes the pig head is a great test model as it's so lacking in planner faces! The workaround splitting the faces first does seem to work fairly well but it would be nice to have a more robust solution out of the box. Thanks, Philip
