Web18 de nov. de 2015 · 1 Answer. Sorted by: 1. The kind of artefacts you're seeing - the squares - are often caused by not sampling some pixels within the blur range. Since you're only using 9 samples, and your blur is quite soft, this is likely the case here. You're effectively blurring a lower-resolution image, but the next fragment over is blurring a … Web17 de jul. de 2012 · Below is the OpenCL code for the Gaussian blur kernel.
