Plugin Details

A Function plug-in for Messiah (ODist.mp), which provides one means to animate tank tracks, wheels, critters, etc., which have to respond to forward and backward motions.

The output from ODist is the forwards (increasing values) and backwards (decreasing values) movement of the control null (positioned at the outside edge of the track), and this number is divided by the length of one tread (0.3865), which is then floor()'ed to remove all but the fractional amount (producing values from 0 to 1.0) and used to control the morph via the SuperBlender slider.
