Multipass Shader Example

cansik

So I finally had the time to create my postfx library for processing. It uses texture shaders and a ping-pong buffer to create post effects with multipass rendering. As there are many questions here in the forum about multipass rendering, I think it could be interesting for you.

Currently implemented are following effects:

• bright pass
• blur horizontal
• blur vertical
• sobel edge detection
• toon filter

I will add more in a few days, but I think also the underlaying structure could be interesting for others, to implement their own multipass shader systems.

Here is the link to the github repository:

For all who are interested in how I implemented it, I have written a tutorial on how to create a bloom filter in processing:

It would be great if you could test my library and give feedback or report a bug. I just tested it on my Mac, but it should also work on windows. Examples are in the examples folder.

Best regards

Holy crap. Genius!
