A blog post describing Smol Gaussian, a blur algorithm that combines downsampling, Gaussian blur, and upsampling to efficiently handle large animated blur radii while maintaining smooth transitions and supporting independent horizontal and vertical blur amounts.
A blog post describing Smol Gaussian, a blur algorithm that combines downsampling, Gaussian blur, and upsampling to efficiently handle animated blur radii. The approach improves upon Dual Kawase by supporting smoothly varying blur radius and independent horizontal/vertical blur, with implementation details similar to Skia's GPU Gaussian blur but with several refinements for better quality and performance.
