Checks whether a point is inside the volume defined by the given #graphene_frustum_t.
a #graphene_point3d_t
Checks whether the two given #graphene_frustum_t are equal.
a #graphene_frustum_t
Frees the resources allocated by graphene_frustum_alloc().
Retrieves the planes that define the given #graphene_frustum_t.
Checks whether the given sphere intersects a plane of
a #graphene_frustum_t.
a #graphene_sphere_t
Allocates a new #graphene_frustum_t structure.
The contents of the returned structure are undefined.
A 3D volume delimited by 2D clip planes.
The contents of the
graphene_frustum_tare private, and should not be modified directly.
