Abstract
A graphics path display has fixed wireframes representing key positions of an image being manipulated. Inbetween wireframes, dots or dashes are generated according to a defined display rate between sequential key positions. The inbetween wireframes are generated by an algorithm selected by an operator, and are adjusted in realtime as the operator changes variable parameters for the algorithm to present a realtime display of the graphics path defined by the algorithm and parameters.
