Description

A tool to compute the spherical harmonics of an environment map.

Features:

* Support for HDR images, both for import and export.
* Compute any arbitrary number of harmonics.
* Compute irradiance.
* Store harmonics or irradiance as a 2D map, for fast sampling in a custom shader.
* Import side-cross cubemaps, or individual faces, and export side-cross cubemaps.
* Import equirectangular maps.
* Rotate cubemaps.
* Save project files, containing images and settings per project.
