A couple of comments, not really answering your question... perhaps others will have more direct suggestions about what is easy to program:
(A) in version 1.6 the shape command includes "cone," so you can make 3D arrows from a cylinder and a cone:
(B) more generally, with the 2dlabels command you can make 2D arrows and then change their locations without recreating them... however, that doesn't solve your problem because you need 3D arrows

Right now, the script creates a .bild file to draw the arrows, but it is not a very good approach since it is creating a new file for every frame of the trajectory. I was wondering if there's a way to do the same thing without having to create the .bild file.
