Subject: raytracing - chess board algorithm

---

Hello,

I currently program a ray tracer using the ray casting algorithm.

I have added the plane primitive and want to improve it in order to get
a chess board.

I wonder how works this algorithm used to get the color switching in
each case.

Can someone explain me how to get this chess board ? (I’m not asking
for source code...)

Thanks for your help.

Psr.
