I don't know what type of rendering engine cycles is. is it path tracing ray tracing Raydiosidi ray casting photon maping? I would like to know

Cycles is a ray tracing renderer. Can use different tracing strategies (under integrator option):

  • Path tracing: pure path tracer.
  • Branched path tracing: path tracer with branching on the first bounce.

It uses Monte-Carlo for sampling, that means repeated random sampling.

Soon Metropolis Light Transport should be also available which is a variant to Monte-Carlo, it uses Bidirectional path tracing and Metropolis sampling.
