Detailed Description

An implicit surface (usually signed-distance function) with a fast collision detection data structure.

Member Function Documentation

void Geometry::CollisionImplicitSurface::DistanceRangeLocal	(	const AABB3D &	bb,
		Real &	vmin,
		Real &	vmax
	)		const

O(1) call to get a range of minimum and maximum implicit surface values within a bounding box, expressed in local frame

void Geometry::CollisionImplicitSurface::InitCollisions

(

)

Sets up the collision detection data structures. This is automatically called during initialization, and needs to be called any time the implicit surface changes
