8. | MATH329 Geometry of Curves and Surfaces at the point (x, y), in the same way that the tangent line {γ(t) + λγ/(t) : λ ∈ R} is the best linear approximation to the regular curve γ at the point t. A proof of this fact requires the two-variable version of Taylor's theorem, so we omit it. Tags:what is surface patch |

9. | principal patches - a new class of surface patch - Semantic Scholar This paper describes a new class of surface patch for use in computational geometry, where fairness is built in at the design stage by using ideas from differential geometry. Principal patches are patches whose sides are lines of cur Tags:what is surface patch |
