Circular Rainbow

Postby mttorley » 27 Sep 2013, 02:58

This brush is more of a calculation then a brush....
This calculation monitors the angle away from the center of the canvas, and selects a point along the gradient according to the angle at which the brush is currently located.

The controller setup can be applied to any other brush parameter, giving rise to many creative options in size, angle, opacity.

The brush is, basically:

(sin((X-.5) / (Y-.5)))/4

It still needs work in the central area close to where X=.5, but, its pretty cool none the less...
