NxBounds3 | _bounds |
Represention of a axis aligned bounding box.
The box is stored as minimum and maximum extent corners. Alternate representation would be center and dimensions. May be empty or nonempty. If not empty, min <= max has to hold.

void PhysxBounds3::bounds_of_obb | ( | const LMatrix3f & | orientation, |
const LPoint3f & | translation, | ||
const LVector3f & | half_dims | ||
) |
Sets this to the AABB (axis ligned bounding box) of the OBB (oriented bounding box).
The OBB is described by orientation, translation and half dimensions.
