RuralPit demo with v4?

[masaki]

R3 required the animpath.dlm plugin to run exported animations. In R4 you need to use the undocumented plugin scenegraphtools.dle.
The following code determines what version (R3 or R4) of Vizard you're running, and loads either the animpath module (for R3) or a wrapper class I've written that runs the scenegraphtools.dle (for R4). With the wrapper class you won't need to change any of your existing code that controls the animation. If you upgrade to R5, animation control is now part of the viz.VizNode object, so you'll have to change your code.

Best,
Masaki

# CHG: animation control depends on R3 or R4!!
