Module lyon_geom::cubic_to_quadratic

Functions

• cubic_to_monotonic_quadratics
• cubic_to_quadratics
  Approximates a cubic bézier segment with a sequence of quadratic béziers.
• cubic_to_quadratics_with_t
  Approximates a cubic bézier segment with a sequence of quadratic béziers.
• single_curve_approximation
  This is terrible as a general approximation but works if the cubic curve does not have inflection points and is “flat” enough. Typically usables after subdiving the curve a few times.
• single_curve_approximation_error
  Evaluates an upper bound on the maximum distance between the curve and its quadratic approximation obtained using the single curve approximation.
