There's not anything built in to reduce the detail during move, but it's quite straightforward to reduce what it displays during a "move vector".

The code that does that bit of drawing is at https://github.com/euphy/polargraphcontroller/blob/master/polargraphcontroller.pde#L1000

Replace that line with:

      int increment = round((pointPaths.length/10.0)+0.5);
      for (int i = 0; i<pointPaths.length; i+=increment)

Where the 10.0 is the proportion of lines to draw. So 10.0 will draw one in every ten lines during "move" time. Changing it to 2.0 will draw every other line. 20.0 will draw one in every twenty lines. Etc.

Is that any good?

Maybe it should only kick in over a certain number of lines ... so only if the artwork is more than 10000 lines or something like that.

I might roll something like this into the next release.

A 'reduce density while moving enormous vector or .g files' function would be lovely in a future release Sandy, especially with mega Death to Sharpie outputs.
