Path tracing can generate realistic images based on virtual 3D scene models, but the images are prone to be noisy. To solve this problem, we developed a novel denoising algorithm framework. Firstly, according to the relative mean square error of the noisy pixels, we introduced a progressive adaptive sampling strategy to optimize the distribution of samples.

Path tracing is a probabilistic rendering algorithm. It looks at possible paths that might have been followed by light arriving at the position of the viewer. Each possible path has a certain probability. Path tracing generates a random sample of possible paths, choosing paths in the sample according to their probabilities.

A novel one- pass di erential progressive path tracing algorithm is introduced which quickly calculates two illumination solutions needed for compositing. Our framework operates in two main modes allowing interaction and high-quality convergence: An interactive preview mode and a progressive re nement mode.

However, progressive algorithms create images exhibiting visual artifacts at early stages. A user study investigated these artifacts' effects on user performance in appearance design tasks. Novice and expert subjects performed lighting and material editing tasks with four algorithms: random path tracing, quasirandom path tracing, progressive photon mapping, and virtual-point …
