I just played with Asymptote outputs viewed on Adobe Reader and noticed the outputs can be zoomed, rotated, filtered which objects to be viewed, etc, etc.
The following screenshot shows the features. The Asymptote output in action is this (click).
My question is how to get the same features for PSTricks (or TikZ) outputs? What packages do we have to load to enable such features? Or is it only possible with Asymptote?
