Web26 dic 2014 · It is non-trivial to get things to blur correctly at the edges of the thread-groups, but as long as you are careful to synchronize the reading and writing of the data then you should be able to make it work with just one texture. WebGaussian blur is an image space effect that is used to create a softly blurred version of the original image. This image then can be used by more sophisticated algorithms to produce effects like bloom, depth-of-field, heat haze or fuzzy glass.

WebThis means the line: blur.x = TextureCoordinate.x + Pixels [i] * pixelWidth; will be equivalent to: blur.x = TextureCoordinate.x; and you will end up with a weighted sum of the same pixel.
