View source for Monte Carlo Integration

In the context of [[Render Engine#Ray Tracing|ray tracing]], Monte Carlo Integration is used to randomly sample an image, in order to accurately compute effects such as soft shadows, glossy reflections, depth of field, motion blur, etc. efficiently.<ref>https://cs184.eecs.berkeley.edu/sp25/assets/lectures/12-integration.pdf</ref><ref>https://graphicscompendium.com/raytracing/19-monte-carlo</ref><ref>https://www.cs.cornell.edu/courses/cs4620/2013fa/lectures/22mcrt.pdf</ref> One side effect of Monte Carlo Integration is the addition of noise, which can be cleared up with either further sampling, or with a [[Denoiser|denoiser]].
