19. Curve Engineering & Class-A Surfacing

Precision curve engineering bridges mathematical rigor and sensual aesthetic quality. This chapter covers porcupine curvature comb diagnostics, the geometric continuity ladder from G0 to G3, Euler clothoid transition spirals, and variational energy-minimizing curve fairing.

1. Curvature Combs & Continuity — Interactive geometrical visualization of porcupine curvature combs and G0 to G3 continuity.
2. Clothoids & Fairing — Interactive geometrical visualization of Euler spirals and variational curve fairing.
