Great shader, gives an amazing effect. Do you mind if I use this shader in my commercial game project? It’s not a huge production and I will provide credit.
Hello…I’m new in GLSL. I tried to place your code in my fragment shader, but I don’t know what I have to write in the main opengl file. Can you help me?
Hi ! Nice ! and thanks for this piece of code. I’m a beginner and have a question.
Could you confirm that we need to render the scene to a textured quad in front of screen and using this shader for only for this “scene quad” ?
Also, I only see a fragment shader code but no vertex shader. Is it possible to only bind a fragment shader without vertex shader ?
Thanks in advance for your answer.

I’m glad you like it :). Of course you can use it for whatever you want to.
YESSS! Thanks a bundle! I had everything in my HDR pipeline working (hi-pass and such) except blooming of highlight values! This did the trick!
This is the best think, I’ve ever seen today 🙂 No, seriously, it’s great.
Very nice shader
i use this code to understand the power of glsl code and test it with DELTA3D OSG (prerender test)
good job
best regards
Perfection!
Very nice, this is exactly the effect I’ve been looking for. Cheers!
is this a vertex or a fragment shader?

I would suggest you read a tutorial on OpenGL. Google “NeHe OpenGL Tutorial”.

Wow! What a great effect! I love it 🙂
It,s great! 🙂 good job! I modified this, and get better results, and faster computing 🙂 thanks for shader! 🙂 sorry for bad english 😀
