I want to visualize a cross belt Sorter with x3dom. The cross belt sorter has a form of a loop with 90° degree arcs. For the cross belts I use:

< Rectangle2D size='0.6 0.6'/>

The Sorter has 58 cross belts and for each cross belt, I want dynamically change the color of the material via javascript. The cross belts should move along the sorter as in real. Therefore I use the tag:

< timeSensor DEF='timeKOSorter' cycleInterval='60' loop='true'>< /timeSensor>

and for example for the cross belt 0:

< PositionInterpolator DEF='POSKO01_0' key='0 0.344 0.355 0.366 0.377 0.389 0.4 0.411 0.433 0.444 0.455 0.466 0.478 0.489 0.5 0.844 0.855 0.866 0.877 0.889 0.9 0.911 0.933 0.944 0.955 0.966 0.978 0.989 1.0 ' keyValue='8.0 0 0.0 -8.0 0 0.0 -8.518 0 0.068 -9.0 0 0.268 -9.414 0 0.586 -9.732 0 1.0 -9.932 0 1.482 -10.0 0 2.0 -10.0 0 3.0 -9.932 0 3.518 -9.732 0 4.0 -9.414 0 4.414 -9.0 0 4.732 -8.518 0 4.932 -8.0 0 5.0 8.0 0 5.0 8.518 0 4.932 9.0 0 4.732 9.414 0 4.414 9.732 0 4.0 9.932 0 3.518 10.0 0 3.0 10.0 0 2.0 9.932 0 1.482 9.732 0 1.0 9.414 0 0.586 9.0 0 0.268 8.518 0 0.068 8.0 0 0.0 '>< /PositionInterpolator>

My problem now is, that if I animate 2 Sorters with each 58 cross belts it costs a lot of CPU time. On my computer it uses more than 40 % CPU power. Have anyone an idea how to achieve a better performance?

If the 58 objects could all move in the same direction, you could just put them all under one transform and make an interpolator for that transform.

If not, maybe try:

http://doc.x3dom.org/author/runtime.html#enterFrame

and change the translation/rotation of the objects via dom manipulation in that function.
