Variance, Noise, and Artifacts in Real-Time Path Tracing
Published:
(work in progress…) Noise is also referred as error, visual artifacts. In ray tracing-based rendering, it is referred to as variance. High variance represents more noise as the number of samples has not converged enough to the actual right result of the integral (Light Transport Equation).
