No, you’re eyes are all right.
This might suprise some of you, but actually I never used or even wrote a single shader program. Why? Well basicly because I haven’t coded so much 3d programs yet. And the shaders of the few that I worked on were written by other people. But to be honest: I always thought of shaders as some black magic voodoo stuff

However this has changed today. I’m currently testing SFML (Simple and Fast Multimedia Library) because I’m planning to write some 2d games in the future.
I already looked at some other 2d multimedia libraries but so far SMFL scores best.

And one cool feature is the shader support of it. So I decided to learn some basic GLSL (SFML uses a slightly modified GLSL for its shaders) and made a simple blur effect in just 10 minutes or so.

I’m so proud of me that I’ll show you the result:

I know nothing special but for a first shader I’m satisfied.

I’ll let you know about this 2d game when there is more to tell.

Happy coding
