I have many OpenGl shaders. We try to use as many different hardware as possible to evaluate the portability of our product. One of our customer recently ran into some rendering issues it seems that t
I am learning to use shaders in OpenGL ES. As an example: Here\'s my playground fragment shader which takes the current video frame and makes it grayscale:
I\'m writing my own shader with OpenGL, and I am stumped why this shader won\'t compile. Could anyone else have a look at it?

I\'ve created a basic orthographic shader that displays sprites from textures.It works great. I\'ve added a \"zoom\" factor to it to allow the sprite to scale to become larger or smaller. Assuming th
