1. A computer implemented method for depicting curves comprising the acts of: receiving a plurality of data structures associated with a first curve; computing a first plurality of line segments to approximate the first curve by using a linear equation, wherein a plurality of the computed first line segments are approximately equal in length to their respective portions of the first curve; providing the computed first line segments to an animation process; receiving a second plurality of line segments from the animation process; computing a second curve to approximate the second plurality of line segments by using the linear equation, wherein a plurality of segments of the computed second curve are approximately equal in length to their respective line segments; and displaying the computed second curve.
