Summary : Decomposes a 3D surface into a set of ���near��� convex parts
Description :
The V-HACD library decomposes a 3D surface into a set of ���near��� convex parts.
Why do we need approximate convex decomposition?
Collision detection is essential for realistic physical interactions in video
games and computer animation. In order to ensure real-time interactivity with
the player/user, video game and 3D modeling software developers usually
approximate the 3D models composing the scene (e.g. animated characters, static
objects���) by a set of simple convex shapes such as ellipsoids, capsules or
convex-hulls. In practice, these simple shapes provide poor approximations for
concave surfaces and generate false collision detection.
Convex-hull vs. ACD
A second approach consists in computing an exact convex decomposition of a
surface S, which consists in partitioning it into a minimal set of convex
sub-surfaces. Exact convex decomposition algorithms are NP-hard and
non-practical since they produce a high number of clusters. To overcome these
limitations, the exact convexity constraint is relaxed and an approximate
convex decomposition of S is instead computed. Here, the goal is to determine a
partition of the mesh triangles with a minimal number of clusters, while
ensuring that each cluster has a concavity lower than a user defined
threshold.
