Equirectangular smooth filter

Description

../../../_images/sphereresolutionfix.jpg

Spherical render without (above) and with (below) the filter

Filter This filter fixes the high noise level caused by the equirectangular projection at the upper and lower parts of spherical renders. The image is filtered anisotropically following the pixel/solid angle projection differential. This ensure uniform resolution and noise levels when projected back on a sphere.

Note

Before Ocean 2016, this filter was named sphere resolution fix
