WebGaussian Blur Shader. I'm attempting to do a 3-pass gaussian blur shader on a texture. The first pass is a horizontal blur, the second pass is a vertical blur, and the third pass is to draw the original image back on top of the two blurred versions. The result I am looking for is what I would describe as a yellow outer glow effect. http://www.sunsetlakesoftware.com/2013/10/21/optimizing-gaussian-blurs-mobile-gpu/index.html WebOct 4, 2015 · Install instructions for Gaussian Blur / Bloom / Unsharpmask for use with SweetFX or MasterEffect. 1.

WebStep 1 is the key here. In the pixel shader version, the source image is sampled multiple times per pixel. In the compute shader version, each source texel is read only once inside a work group. Texture reads usually use a tile-based cache, but this cache is still much slower than shared memory. The gaussian filter is one of the simpler examples.
