Simplest and Fatest GLSL Edge Detection using Fwidth

GLSL Edge Detection Yesterday, I read 834144373’s ShaderToy code which did GLSL Edge Detection in 97 chars, it was really simple and fast:

Meanwhile, the rendering result is astonishingly awesome: However, there are some noise from the GLSL edge detection. Thus, I have made a little improvement on this algorithm and produced cleaner edges in this ShaderToy…


Testing GPUs Computational Power

Have you think of how many summation & multiply operations can you do within for-loops in GPU fragment shader? I irrigorously tested the following fragment shader on ShaderToy, which gives me 100,000 operations at 22 FPS on a GTX 1080, for 25, 000 operations, it runs smoothly at 60 FPS. So, what’s the limitation of…


404 Not Found in Two Triangles

Inspred by 104 from ShaderToy, I made a new 404 Not Found page with two triangles in GLSL using calligraphic strokes. Live Demo Please visit: http://duruofei.com/404 or   Code
