Hello-- I'm using vPython to animate some data... I'm adding a feature which allows the user to step forward and back in time frame by frame, and when the user "rewinds," I want to delete part of the trail the object left (I don't want to make the whole trail invisible, just part of it). To add to the trail, it's just trailName.append(whatever)... does anyone know if there is a trailName.pop() or trailName.remove() or something like that would allow me to unappend data points from a curve object? Thank you! Jennifer Anttonen Harvard University je...@gm... |
