GoKawiilDeveloper releases Smol Gaussian blur technique with interactive WebGPU demo
A developer documents a year-long exploration of blur algorithms sparked by performance issues with Blender's Fast Blur mode, ultimately combining existing techniques into an approach called Smol Gaussian. The method uses a downsample-blur-upsample strategy to handle smoothly animated blur radii and independent horizontal/vertical blur amounts, addressing limitations found in the popular Dual Kawase blur technique. An interactive WebGPU playground is provided alongside the writeup for readers to test the technique.
