WebGLSL gives us two interesting input variables called gl_FragCoord and gl_FrontFacing. gl_FragCoord. We've seen the gl_FragCoord a couple of times before during the discussion of depth testing, because the z component of the gl_FragCoord vector is equal to the depth value of that particular fragment. However, we can also use the x and y ... WebMay 5, 2015 · 2. To apply blur to transparent texture you need use alpha to correct. There is simplified formula for one pixel: resultColor = (sum of pixels of input image) * 1 / K; Commonly K is kernel size. If you blur transparent texture you need accumulate alpha and use it as K. resultAlpha = (sum of alpha pixels of input image); resultColor = (sum of ...
