Member Function Documentation

- (BOOL) doesIntersectPointAt:

(CC3Vector)

location

Returns whether the specified global location intersects (is inside) this frustum.

- (BOOL) doesIntersectSphereAt:		(CC3Vector)	location
withRadius:		(GLfloat)	radius

Returns whether a sphere, centered at the specified global location, and with the specified radius, intersects this frustum.

+ (id) frustum

Allocates and initializes an autorelease instance.

- (void) populateFromProjection:		(CC3GLMatrix *)	aProjectionMatrix
andModelView:		(CC3GLMatrix *)	aModelViewMatrix

Populates this frustum from the specified projectionMatrix and modelviewMatrix by multiplying the two matrices together and extracting the six frustum planes from the resulting model-view-projection matrix.
