Feedback in Processing 1.0

Proof of concept version in processing 1.0 to reproduce feedback effect.
It takes the screen image as texture for the feedback plane.

PROCESSING SOURCE CODE: feedback_2.zip
Demo video on youtube: Feedback demo



I am also coding on a more clean optimized version in Qt and OpenGL. I will upload first source code during next week (depends on time I will have ;) ).



Keys:
o switch between objects (either feedback plane or input plane)
s render grid lines of object
+ increase object size
- decrease object size

r enables/disables relief on feedback plane
3 decrease grid res of feedback plane
4 increase grid res of feedback plane

p enables/disables input plane
a enables/disables input plane rotation

t Texture Mode on/off

Randomness of texture coordinates on feedback plane
g switch random mode (1=random,2=noise,3=deterministic function)
1 decrease influence (default influence=0)
2 increase influence
