Thanks, will be very helpful.

ppMath.c seems to be useless?

Ah, yes. Thanks for the hint. Will be removed with the next shader.

That even is a feature that AAA-Engines still advertise currently, it looks really good!

great to have a pp effect to transform colours colder or warmer, this way my levels have a more integrated appearance, many thanks, I really need it, and merry Xmas!

I added a Film Grain effect. It supports different approaches used in digital photography, films and games. Except simple noise, almost all modes base upon actual film grain samples, as a texture or a video stream. Following is a screenshot, which hardly captures the effect - you have to run the demo in order to recognize the differences; the download is in the first post of this thread.

Film Grain effect:


The first mode is procedural and calculates for each pixel random noise. The other modes tile or scale a grain-texture onto the screen in each different manners. A stream-mode takes a video file from actual film grain footage and streams it on the screen which is done pretty often in the film industry. You can buy footage at Pond5, iStockphoto or Cinegrain.com. Included in the download is a free grain sample.

It's nice to see this progress with always high quality features.

You've done a great job (and I think this will stay the same in the future)

Thanks Kartoffel you were lately into HDR, are you willing to share code so that I can implement it?

Yea, but the code is complex, dirty and needs some optimization

That won't be a problem, I guess

You, Sir, are awesome. I love it. I especially think that your code is beautiful. I can't reason about it, but I'm stunned everytime I have a look at your code about its clarity.
