3. NON-PARAMETRIC REPRESENTAION. In general a surface or surface patch
is represented analytically by an equation of the form. Where P is the position
vector. The natural choice for f(x,y) is a polynomial. Thus for analytical

Polynomial Surface Patches. • S(s,t) is typically polynomial in both s and t. –
Bilinear: – Bicubic: x(s,t) = ast + bs + ct + d x(s,t) = (at + b)s + (ct + d) -- hold t
constant ⇒ linear in s x(s,t) = (as + c)t + (bs + d) -- hold s constan

surface is thus viewed as a collection of homeomorphisms σ : U → S ∩ W, which
are called surface patches. The collection is called the atla

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.

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

Full Screen. Close. Quit. We will also quote Bonnet's theorem about the existence
of a surface patch with prescribed first and second fundamental form. This will

Theorem. Given a patch σ : U → S ⊂ R3 for the smooth surface S and a point p
∈ U. Composition with projection There exists an open subset U/ ⊂ U containing
p and a projection π : R3 → R2 to one of the coordinate planes such that th
