1. Motivation and related work Most physically-based rendering engines solve the rendering equation through Monte Carlo integration. This process produces noisy images that can only be removed by computing more samples, or by using denoisers (e.g., [SFA*24]) or more efficient importance sampling algorithms. Even though denoisers are nowadays efficient, the final image depends on the quality of the input image, which is why the development of low variance sampling algorithms is still required.
