Denoise filtering
The Patchwork 3D rendering engine supports the new algorithms for intelligent noise reduction by NVIDIA Iray. During progressive refinement it is now possible to obtain a noise-free rendering from a threshold defined in advance.
From the user-defined threshold of the Minimum iterations, intelligent noise reduction algorithms perform a process to make the image look sharper.
The higher the threshold, the more intelligent noise reduction occurs late in rendering.
The lower the threshold, the more intelligent noise reduction occurs early in rendering.
