Web10 dic 2006 · There are 2 simple ways to increase "depth" of gaussian blur without changing kernel size. One way is to downsample the input texture - kernel size, weights, shader code don't change, you only need to pass a new size of the texture (or precalculated offsets) to the shader. It's described i.e. here (slides 46-53). WebCheck @amilajack/glsl-fast-gaussian-blur 2.0.0 package - Last release 2.0.0 with MIT licence at our NPM packages aggregator and search engine.
