Distribution of spines on a curvature comb

A computer-implemented graphics program that determines the distribution of spines on a curvature comb. The graphics program generates a curvature comb to visualize the smoothness of a curve, wherein the curvature comb is comprised of a plurality of spines drawn perpendicular to the curve. The spines are distributed along the curvature comb according to a spine density function (SDF) that represents a desired density of the spines. A cumulative density function (CDF) is used as a computational tool for distributing spines according the distribution given by the SDF.
