Copy sequence of dataset images where indices move on a parametric curve.
misc/extract_parametric parameters.json out_dirname/ frames
Copies frames images from the dataset into files in out_dirname/ with sequentially numbered names, where the view indices evolve according to a parametric equation (x,y) = f(t).
The equation can be set in the script (function f(t)). t evolves from 0 to 1 (in count) steps, and it must return two values x, y from 0 to 1. The program converts this into valid view indices.
Preset are a figure 8, a spiral, a circle.
