By jnorthrup:

you ported java timers using long's.

since javascript does not provide a native long your timer code is doing double->int[] conversions. i could find no issues with the threejs port except for the timer which is a known failing of js. for this reason you should probably use jsni timing harnasses and animation for apples to apples comparison.
