apply_scale_factor(scale_factor)[source]
update_following_reflection()[source]

Notification that incident light is following reflection.

from_first_order(nu_before, nu_after, y)[source]
normal(p)[source]

Returns the unit normal of the interface at point p.

intersect(p0, d, **kwargs)[source]

Intersect an Interface, starting from an arbitrary point.

Parameters:
  • p0 – start point of the ray in the interface’s coordinate system

  • d – direction cosine of the ray in the interface’s coordinate system

  • z_dir – +1 if propagation positive direction, -1 if otherwise

  • eps – numeric tolerance for convergence of any iterative procedure

Returns:

distance to intersection point s1, intersection point p

Return type:

tuple

Raises:

TraceMissedSurfaceError
