Ray casting-based method
WebOct 24, 2024 · Path tracing is a type of ray tracing. When using path tracing for rendering, the rays only produce a single ray per bounce. The rays do not follow a defined line per bounce (to a light, for example), but rather shoot off in a random direction. The path tracing algorithm then takes a random sampling of all of the rays to create the final image. WebTo implement the algorithm we will add a contains method to the polygon class. To use the method you create a polygon and pass a point to the polygon's contains method. The …
