Detailed Description

Temporal shadow denoiser for ray traced shadow masks based on the Qualcomm Shadow Denoiser algorithm.

ShadowDenoiser reduces noise in a ray traced shadow mask by accumulating and filtering samples across multiple frames. It uses depth-based reprojection to carry history from the previous frame, rejects disocclusions via depth min-max comparison, and applies a spatiotemporal filter to reconstruct a clean shadow signal from a one-sample-per-pixel input.

Since: Kanzi 4.1.0

Attention: This feature is experimental and is likely to change in future releases.
