Class IntersectionTester

java.lang.Object

ca.blarg.gdx.math.IntersectionTester

public final class IntersectionTester
extends Object

Various intersection tests between 3D geometric shapes. Note that libgdx's own Intersector does implement some of these tests already, but not all of them. I've just included all of these here for consistency's sake and to make porting some of my other projects easier.
