OBB::ClosestPoint
Syntax
float3 OBB::ClosestPoint(const float3 &point) const; [9 lines of code]Computes the closest point inside this OBB to the given point.
The implementation of this function is from Christer Ericson's Real-Time Collision Detection, p.133.
If the target point lies inside this OBB, then that point is returned.
Performance
28.737nsecs/call ≈ 34.8M calls/second ≈ 579.98k calls/frame (@ 60fps).
This function does not perform dynamic memory allocation.

Work in progress:
Todo: in float3 OBB::ClosestPoint(const float3 &point) const:
Add ClosestPoint(Line/Ray/LineSegment/Plane/Triangle/Polygon/Circle/Disc/AABB/OBB/Sphere/Capsule/Frustum/Polyhedron).
