Re:A reasonably speedy Python ray tracer by CyberDildonics on Saturday October 21, 2017 @04:20PM (#15523423)
The simple answer is no, but unless there is an error the rays will at least be traced from the reflection angle. All light you see bouncing off of hard surfaces is some sort of reflection and even for sharp reflections there are a lot of details.

One is fresnel falloff towards edges, which is simple. Another is depth of field carrying into reflections, which is more difficult and not common (yet).
