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.
:
: The v-hacd-tools package contains command-line tools based on the V-HACD
: library. Currently, this means TestVHACD; despite the name, this tool has
: general utility beyond testing.
