Tool to help visualize trajectory arcs and animation. Used as a quick reference to help animators with projecting or falling objects & characters.
Will have to post a vid tutorial for this one.
to use
source script,
type trajectoryVis; in command line
Move the controls around to see the resulting trajectory arc.
With the "finger" control selected you'll notice 2 key frames in the time slider, these mark the start and end of the animated trajectory marker. Moving the keys changes the when and how long the marker takes to travel across the trajectory.
