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.
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().
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.
