Decoupling Noise and Features via Weighted l_1-analysis Compressed Sensing

A two-phase approach that estimates a base mesh from input noisy data and recovers the features from the residual by using l_1-analysis compressed-sensing optimization.

Topology-Varying 3D Shape Creation Via Structural Blending

Introducing an algorithm for generating novel 3D models via topology-varying shape blending. Given two shapes with different topology, the method blends them topologically and geometrically, and produces plausible in-betweens representing new creations.

Continuity Transition With a Single Regular Curved-Knot Spline Surface

This paper proposes a specialized form of the curved-knot B-spline surface. The monotonic blending of the knots allows for constructing smooth transitions between B-spline boundaries with different knot vectors.

l1-Based Construction of Polycube Maps From Complex Shapes

This technique automatically creates polycube maps by minimizing the l1 norm of the boundary normals to align the normal field of an input shape to three orthogonal directions. Regularizing this minimization with surface and volumetric distortion energies allows for a controllable and versatile tool for polycube generation.

Harmonic Parameterization by Electrostatics

By applying ideas from electrostatics to parameterize the open space around an object, this paper presents an object-centric coordinate system called Electric Coordinates. It has several applications in computer graphics, including: texturing, morphing, meshing, path planning relative to a target object, mesh parameterization, designing deformable objects, and computing coverage.
