Best parameters for decomposing a gear #59

Open AndreaIncertiDelmonte opened 5 years ago

AndreaIncertiDelmonte commented 5 years ago

I'm trying to decompose this gear:

Using the following parameters:

I obtained the result below:

How should I improve the quality of the decomposition? I would like that the central hole will be as circular as possible.

Try increasing the resolution, the number of points per CH, the number of convex hulls and decrease the minimum volume

For gears I noticed HACD typically seemed getting better result than VHACD, though volume was not preserved. Maybe you can try and compare them.
