Convert the (x,y) curves to surfaces in the (x,y,time) domain and you should get a representation that is very fast to evaluate. With fast forward differencing

Convert the (x,y) curves to surfaces in the (x,y,time) domain and you should get a representation that is very fast to evaluate. With fast forward differencing, animating the curves would only need 6 adds per control point. If you are fine with "A Scanner Darkly"-style video it would work great! BTW: Vector videos have been used to squeeze full-screen cinematics into a Super Nintendo: http://fabiensanglard.net/anotherWorld_code_review/index.php http://fabiensanglard.net/anotherWorld_code_review/index.php
