Is there a reason that a Path Tracer doesn't just start with a quick Ray Trace and then layer the extra paths on top of it? I've seen the effects mentioned where you limit bounces of a Path Tracer and the resulting image looks grainy. Why not start with a Ray Trace and blend a limited Path Trace on top? I would guess that even a full resolution
Ray Trace blended against a quarter resolution Path Tracer with a high bounce limit would give a pretty good image right?
- Asooka 8y agoThat's pretty much how commercial ray tracers work. Path tracing for scattered rays and GI, with ray tracing for evaluating direct light. Look at Cycles's code.
