Dim distance On – Enables the Dim distance parameter which allows you to stop tracing reflection rays after a certain distance.
WebJump to heading # Naive Path Tracing. After roughly following the raytracing in one weekend book, I ended up with a naive path tracer that just randomly sends out rays and results in a radiance contribution if the ray ends up hitting a light source. Naive path tracing. As you can see in the image above, the result is noisy. WebNov 13, 2024 · As we can easily see from the comparison, subsurface scattering shows a more waxy feeling, it feels more transparent than the Lambert BRDF. In a nutshell, …
