Initializes the given Frustum using the
provided clipping planes.
- public unowned Frustum? init_from_frustum (Frustum src)
Initializes the given Frustum using the
clipping planes of another Frustum.
- public unowned Frustum? init_from_matrix (Matrix matrix)
Initializes a Frustum using the given
matrix.
- public bool intersects_box (Box box)
