In ray tracing, each ray is tracked back to one or more light sources by computing its precise path of reflection or refraction.
Path tracing generates several rays for each pixel, but they bounce off in arbitrary directions.
Ray tracing shoots one ray from each pixel. Path tracing doesn’t send one ray but tens, hundreds, or thousands of each pixel rendered.
