Today I did some experiments to try to figure out why the animations I’ve created seem to hitch and hiccup slightly from time to time. Again, this work is based on recreating the basic functionality of the Greensock animation product described here<\/a> and especially here<\/a>.<\/p>\n

The first thing I thought of was that the drawing operations themselves might be taking long enough that they don’t complete during every animation step (about 16 ms at 60 frames per second). I therefore set the update loop to only draw the items every other scan. This approach didn’t relieve the hitching and updating at 30 fps left the animation looking slightly choppy.<\/p>\n
