Introducing the novel 3D modeling tool PushPull++. which enables rapid modeling and adjustment of arbitrary meshes with slanted surfaces. PushPull++ reduces the required clicks for common modeling tasks up to an order of magnitude compared to leading commercial tools.

Flow-Complex-Based Shape Reconstruction From 3D Curve Sketches

Introducing an algorithm for shape reconstruction from a sparse collection of 3D curves, based on the flow complex. The algorithm produces intersection-free 3D-triangulated shapes that interpolate input curves.

True2Form: 3D Curve Networks From 2D Sketches via Selective Regularization

True2Form is a sketch-based modeling system that reconstructs 3D curves from single-view design sketches. The method infers 3D form from drawings using a novel mathematical framework of insights derived from perception and design literature. Results are demonstrated on numerous inputs and validated via a user-study.

Interactive Shape Modeling Using a Skeleton-Mesh Co-Representation

A polar-annular mesh (PAM) is a polygonal mesh with a structural constraint that imbues a PAM with both a parts segmentation and a skeleton. In the proposed multi-touch shape-modeling system this co-representation makes coarse changes efficient as well as interoperable with surface sculpting and refinement.

Vector Graphics Complexes

Introducing the vector graphics complex, a simple data structure that supports non-manifold topological modeling for vector-graphics illustrations. The representation faithfully captures the intended semantics of a wide variety of illustrations and is a proper superset of scalable vector graphics and planar map representations.
