public class btConvexHullShape
extends btPolyhedralConvexAabbCachingShape

The btConvexHullShape implements an implicit convex hull of an array of vertices. Bullet provides a general and fast collision detector for convex shapes based on GJK and EPA using localGetSupportingVertex.

Constructor Detail

btConvexHullShape

public btConvexHullShape(Pointer p)

Pointer cast constructor. Invokes Pointer(Pointer).

btConvexHullShape

public btConvexHullShape(long size)

Native array allocator. Access with Pointer.position(long).

btConvexHullShape

public btConvexHullShape(@Cast(value="const btScalar*")
                         DoublePointer points,
                         int numPoints,
                         int stride)

this constructor optionally takes in a pointer to points. Each point is assumed to be 3 consecutive btScalar (x,y,z), the striding defines the number of bytes between each point, in memory. It is easier to not pass any points in the constructor, and just add one point at a time, using addPoint. btConvexHullShape make an internal copy of the points.
