tank rig problem in maya

[nuternativ]

hi,
Here http://www.youtube.com/watch?v=yA0MtUr2Xbs&playnext=1&list=PLD4BC07467D835E74

The clip demonstrates an easy way to rig a tank track using wire deformer.
By using this method, the track need to be modelled in a perfect circle shape.

hope this helps.

HI,

This is my video to understand the problem (rotation problem)

http://www.youtube.com/watch?v=_JC1Bm7SkL4

and this my expression :
*********************************************
float $radius = 5;

float $Zval = ctrl.translateZ ;
float $Xval = ctrl.translateX;
float $distance = ($Zval * $Zval) + ($Xval * $Xval);
$distance = sqrt($distance);
float $rotation = $distance / (2 * 3.412 * $radius) * 360;

tank.rotateX = $rotation;
*********************************************
i hope to find a solution

thanks
