Hi- I coded interpolation between arbitrary pymol views in slerpy using quaternions. You may be able to recycle some of that. See:

The PyMol script receives the coordinates from OpenCV and changes the camera orientation accordingly in a loop so it is not possible to use scenes. The only solution I have found so far is to decompose the movement : ### for i in range(10): cmd.turn('x',x_angle/10) cmd.turn('y',x_angle/10) cmd.refresh() ### Quoting Jason Vertrees <jason.vertr...@schrodinger.com>: > Hi, > > If you're only zooming around scenes with the camera, and not using > object motions, then "scenes" are the best way to go: > > fetch 1oky > scene 001, store > > zoom br. first org > scene 002, store > > ### cut below here and paste into script ### set_view (\ > 0.704781950, 0.201942384, -0.680074394,\ > -0.689321160, 0.421526819, -0.589196265,\ > 0.167686298, 0.884044886, 0.436287463,\ > 0.000000000, 0.000000000, -32.830085754,\ > 82.917518616, 17.755170822, 12.337598801,\ > 28.110042572, 37.550128937, -20.000000000 ) > ### cut above here and paste into script ### scene 003, store > > Now you can recall the scenes via a script: > > scene 001, recall > > or you can use the pg-up and pg-down keys to interactively transition > to the next scene.
