The dynamic distance modifier allows you to dynamically (once per frame)
|
||
|
|
change the source pixels for each ring of pixels out from the center.
|
||
|
|
In the 'pixel' code section, 'd' represents the distance in pixels
|
||
|
|
the current ring is from the center, and code can modify it to
|
||
|
|
change the distance from the center where the source pixels for
|
||
|
|
that ring would be read. This is a terrible explanation, and if
|
||
|
|
you want to make a better one send it to me.
|
||
|
|
|
||
|
|
Examples:
|
||
|
|
Zoom in: 'd=d*0.9'
|
||
|
|
Zoom out: 'd=d*1.1'
|
||
|
|
Back and forth: pixel='d=d*(1.0+0.1*cos(t));', frame='t=t+0.1'
