Glass Block Effect
Author
Hello!
I want to create a Glass Block effect like in Corel PhotoPaint. What is the algorithm for this filter? I would be pleased to see some code or a detailed description.
Thank you in advance.

I think render-to-texture and then pasting it onto a grid of quads (with "overlap" to create the effect) might work. Presuming you meant in real time, of course.
that''ll work.
or if you''re bored:
Dd what he says, and then have another "window texture", where that''s a normal map representing the window normals. Then look up from the normal map, and use the refract() function to do a lookup into the texture.
Could look cool
