mapPixel() is very slow
Hi I tried to implement a shader with the mapPixel() function. Each time before drawing a picture, I apply a function which change the brightness of a pixel acording to the mouse position. That worked out so far. But crux about this, this simple function drops my FPS to 2!! Does anyone know a way ho...
