16.2.1 - collision-shape splitting

• Bugfix: assertion failure in VHACDHull after a failed decomposition

• Added the pairTest() method to the CollisionSpace class.

• Implemented collision-shape splitting:

  • Added split() methods to 7 classes:
    • ChildCollisionShape
    • CompoundCollisionShape
    • CompoundMesh
    • GImpactCollisionShape
    • HullCollisionShape
    • IndexedMesh
    • MeshCollisionShape
  • Added the canSplit() and toSplittableShape() methods to the CollisionShape class.
  • Added some constructors to 5 classes:
    • CompoundMesh
    • GImpactCollisionShape
    • HullCollisionShape
    • IndexedMesh
    • MeshCollisionShape
  • Added the toHullShape() method to the ConvexShape class.

• Implemented center/volume estimation for collision shapes:

  • Added the aabbCenter() and scaledVolume() methods to the CollisionShape class.
  • Added the maxMin() method to the CompoundMesh class.
  • Added volumeConvex() methods to the DebugMeshCallback and DebugShapeFactory classes.
  • Added the copyTriangle() and maxMin() methods to the IndexedMesh class.

• Added math classes:

  • DistinctVectorValues
  • MyVolume
  • RectangularSolid
  • Triangle
  • VectorSetUsingBuffer

• Added math methods:

  • MyBuffer.covariance()
  • MyBuffer.maxMin()
  • MyBuffer.mean()
  • MyMath.cube()
  • MyMath.mid(float, float, float)
  • MyMath.min(float...)
  • MyMath.modulo(int, int)
  • MyMath.transformInverse() for a Triangle
  • the normal-and-displacement constructor for a Plane
  • Plane.pseudoDistance()
  • Vector3f.crossLocal()
  • Vector3f.distance()
  • Vector3f.mult(float, Vector3f)
  • Vector3f.mult(Vector3f)

• Added the FastMath.QUARTER_PI constant.

• Added the VectorSet interface.

• Added supplemental V-HACD methods:

  • VHACDParameters.toMap()
  • Vhacd4Parameters.nextFillMode()
  • Vhacd4Parameters.toMap()

• Updated the Bullet sourcecode to match SHA1 ID=dad061fc1 of the bullet3 project.
