We cannot reproduce the slow playback you’re getting with the per-frame cones. Our guess is that it’s something else with the trajectory that’s problematic. Does it have a large nucleic acid in it (with abstracted “Nucleotides” depiction?). Do you have a molecular surface present (even if hidden [check the Model Panel])?

Hi,

I'm running MD simulation and I would like to display forces vectors "live". My strategy is to run:

MD Movie -> PerFrame Script -> In this script create a shape (cone), and update it every frame. I transformed my vectors into ration axis and angle, and run it. However it works extreamly slow, and even lowering quality of cone didn't help. Do you have any clues?

Here is how my script looks like:

#1: close #1; shape cone radius 0.2 height 3.051701874476991 center :47 divisions 10 color red rotation 1.003198923120698,-0.8433298543660601,-0.5373867542336597,180
#2: close #1; shape cone radius 0.2 height 3.054021942152826 center :47 divisions 10 color red rotation 1.0022878678774028,-0.8433406134841704,-0.5373745205242975,180
