		type(t_ray), intent(in)	ray,
		logical, intent(in)	has_normal )

Apply transformation and compute the distance.

Parameters

[in,out]	intersection	Intersection.
[in]	transformation	transformation.
[in]	ray	ray in the original frame.
[in]	has_normal	Apply transformation to the normal.

rt_intersection_partial_initialization()
