How to implement GLSL(or WebGL) as a filter in Photoshop?

[mimozemská hůl]

Hello,

I need to know how to implement GLSL(or WebGL) as a filter in Photoshop, i.e. to manipulate pixels like a common c++ plugin filter. If someone is into this field, please point me to some documentation on how to do this because I cannot find anything on the internet on this matter.

Thank you,

Damian
