 # Amida: 2D Lighting using Radiance Cascades
 
-This program implements 2d lighting using the [radiance cascades](https://radiance-cascades.com/) algorithm by Alexander Sannikov, using the bilinear fix to prevent ringing. It also supports multiple bounces using subsurface scattering and volumetrics.

 ## Usage
 
+Note: This program requires a NVIDIA graphics card due to using CUDA.
