WebJun 12, 2016 · This can be further optimized on some devices (notably PowerVR) by using non-dependent texture reads. This can be done by calculating the texture coordinates in the vertex shader, and passing them as varyings to the fragment shader. This is left as an exercise for the reader to keep this module simple. You can read more about it here.

WebEdge Detection Outlines 4minute read Jump to heading#Introduction Imagine we give our shader the image below on the left and we want the shader to generate an outline for us. We could simply detect if there is a sudden color discontinuity, and if … WebEdge detection is an image processing technique that identifies regions where there is a significant change in the brightness of the image. It provides a way to detect the boundaries of objects and changes in the topology of the surface.
WebMay 30, 2016 · This will have the side effect of getting rid of any noise that's smaller than the blur kernel, but it will also thicken the lines you end up drawing, too. Apply a post-process where you thicken the lines by either stamping a shape at every point that's an edge, or using some sort of dilate process.
