Having been helped to solve some difficult problems with shaders, I can see how useful they are. But for most users, including myself, they are too hard to build.
So a library of useful shaders would be - well, very useful.
I’m happy to help compile it - I know of Andrew Stacey’s demo shaders, and I have a couple spacemonkey wrote for me, but do any of you have any shaders that do really useful or cool stuff? If you do, could you share, including a working demo that shows how to use it as simply as possible?
