HACD/GImpact Determinism

Post by KKlouzal »

I have a couple questions about HACD, GImpact, and determinism.

I understand HACD allows you to take a concave polygonal mesh and reduce it down to many convex objects. How deterministic is this process?

I'm not very familiar with GImpact can it be used for the same reason stated above? If so how deterministic is that process?

Lastly what are the key differences/main use cases for the two?


Thank you for your time.

From my experience, Gimpact decomposition is very deterministic, while HACD may not have been as much. HACD has a chance of creating better shapes for you, however. Don't take my word for 100% truth as I haven't played with HACD in about 4 months, where rotations of objects could have been affecting my input vertices, causing non-deterministic effects.

I'm having a hard time imagining why either algorithm would yield non-deterministic results, but I'll have to get back to you about that once I look deeper into HACD's code again.
