| void btCompoundShape::calculatePrincipalAxisTransform | ( | const btScalar * | masses, |
| btTransform & | principal, | ||
| btVector3 & | inertia ) const |
computes the exact moment of inertia and the transform from the coordinate system defined by the principal axes of the moment of inertia and the center of mass to the current coordinate system. "masses" points to an array of masses of the children. The resulting transform "principal" has to be applied inversely to all children transforms in order for the local coordinate system of the compound shape to be centered at the center of mass and to coincide with the principal axes. This also necessitates a correction of the world transform of the collision object by the principal transform.

The btCompoundShape allows to store multiple other btCollisionShapes This allows for moving concave collision objects. This is more general then the static concave btBvhTriangleMeshShape. It has an (optional) dynamic aabb tree to accelerate early rejection tests.
