## Detailed Description

A structure for holding intermediate values for length calculations of a bezier spline.

This structure has a public alias `hpgs_bezier_length` and holds internals of a bezier spline used during length calculations.

## Field Documentation

double hpgs_bezier_length_st::l[HPGS_BEZIER_NSEGS+1]

The length of the spline from the beginning to the parameter -0.5+i/HPGS_BEZIER_NSEGS.

Referenced by hpgs_bezier_length_init(), and hpgs_bezier_length_param().

double hpgs_bezier_length_st::dl[HPGS_BEZIER_NSEGS+1]

The derivative of the length of the spline at the parameter -0.5+i/HPGS_BEZIER_NSEGS.

Referenced by hpgs_bezier_length_init(), and hpgs_bezier_length_param().
