Unity 2D Radiance Cascade Demo

This repository provides a basic implementation of a global illumination technique based on the concept of Radiance Cascades, as described in the paper Radiance Cascades: A Novel Approach to Calculating Global Illumination.

The illumination algorithm is applied as a post-processing effect on the main camera.

The repository includes two versions of the algorithm:
3D Texture Implementation: For easy understanding of the technique.
2D Texture Implementation: For greater portability across different platforms.

I have tested it with different resolutions, and the highest one has put my high-end GPU to work taking 22 ms per frame. Would be interesting to check it in a real project and play around with values to find an optimal compromise.
