Noise Comparison: Animated Results of the Cabana Dam Break Dataset

An illustration of different volume rendering strategies for the Cabana Dam Break dataset over time. Emission and Absorption is fast but fails to convey depth. Single-Scattering highlights depth through shadows, but requires time to converge. Null Collision methods decorrelate input random numbers from output luminance, causing to significant noise in single sample per pixel configurations. Stochastic Ray Marching preserves this correlation, allowing for blue noise patterns in the final image structure of single-sample-per-pixel images, greatly improving image clarity.
