Cubic Lens Distortion + Chromatic Aberration Custom IPP

Hey guys,
I've been studying the possibility to make a chromatic aberration effect by using native wz4 tools. The best solution I found was to use ModMaterial channel masking + slight amount of Crashzoom effect + Rendertarget Layer2d compositing. Eventually that approach didn't prove feasible: to split RGB channels properly I had to copy each material 3 times and use a separate rendertarget for each one. It's too complicated...

Instead I used a CustomIPP effect based on this shader: http://www.francois-tarlier.com/blog/cu ... on-shader/
I slightly modified it so that individual RGB channels are available for tweaking. Many thanks to the author for a wonderful and simple solution. Credits also go to ikam for the awesome custom IPP effect (how are things with ye, bro? :)).
Enjoy :)

Cool! Maybe we can get stereo 3d?... :lol: In wz3 was stereo 3d, but it was terrible imho.

Anaglyph Shader? Do we actually need it? FB made only one demo using it. Was it called Candytron? ;)

All we do in wz is 3d. So, what strange if it will be more 3dreal? In FR demo was terrible implementation of 3d anaglyph in their demo, imho...

Yes, but who brings 3d glasses to demo parties? ;)

Maybe it is a future of demoscene? Why not?)))

Technologically wz4 is growing antique. Let's just hope ikam reinvents it in his new tool! :)
