We describe a method for free form surface design that uses a mesh formed by networks of curves of minimum energy to define surfaces satisfying position, normal, and curvature constraints. The work addresses difficult problems arising in solid modeling, specifically at difficult blending problems, e.g. a blend at a high order vertex with simultaneous convex and concave blends incident to it. The techniques that we describe here may also be applied to general free form surface design. Previous…

Minimum curvature variation curves, networks, and surfaces for fair free-form shape design
TLDR
This work presents a new technique for curve and surface design that combines a geometrically based specification with constrained optimization (minimization) of a fairness functional, and demonstrates the superiority of curvature variation as a fairness metric and efficacy of optimization as a tool in shape design, albeit at significant computational cost.
Functional optimization for fair surface design
TLDR
A simple-to-use mechanism for the creation of complex smoothly shaped surfaces of any genus or topology that allows the specification of a desired surface in the most natural way and produces very high quality surfaces with predictable, intuitive behavior.
Geometric modeling using high-order derivatives
TLDR
This work presents a novel discretization for both problems based on the mixed finite element framework and a regularization technique for solving the resulting, highly ill-conditioned systems.
Transfinite surface interpolation with interior control
Ribbon-based transfinite surfaces
Blending Polyhedra with NURBS
TLDR
An approach of blending edges and vertices of a polyhedron using NURBS surfaces with C1 continuity along their common boundaries is presented and can unify the transaction of these two cases.

Scale-Invariant Functionals for Smooth Curves and Surfaces
TLDR
The use of a functional that minimizes curvature variation rather than bending energy leads to shapes of superior fairness and, when compatible with any external interpolation constraints, forms important geometric modeling primitives: circles, helices, and cyclides (spheres, cylinders, cones, and tori).
Möbius-invariant curve and surface energies and their applications
TLDR
A simple modification of the minimum variation energy is suggested and it is demonstrated that the resulting modified MVS enjoy Möbius invariance (so it is called conformal-invariant MVS or, shortly, CI-MVS).

TLDR
The simple equation ± w = Vcos (ip — y) is found and solved to find the equation of the curve of least energy in Whewell form, and a differential equation for the curve in Cartesian coordinates aligned with the axis of symmetry is developed.
