Thin-plate form design and exploration
An interactive tool for thin-plate forms design and exploration is invented in this project. Thin-plate forms are designed by specifying target folds. It can also be used to simulate both rigid and nonrigid origami.

Computer aided Mechanical Assembly Modeling
A CAD/CAE integation project on Mechanical Assembly Modeling. We aim to model the mechanical assembly from a prescribed function of the assembly.

Planar Quadrilateral Mesh Design for Freeform Architecture surfaces
A construction-aware geometric modeling project. We design a modeling framework for user to control and desing quad meshes on freeform surfaces.

Improving Subdivision Surfaces' Quality
We propose a shape modeling framework using subdivion. Both the surface quality and modeling flexibility are improved under this modeling framework.

Sudivision Curves Design With High Quality
We propose a class of global subdivion curves, with a higher quality on curvature distribution.

Precision control in discrete surface stitching
We present a discrete surface stitching algorithm for CAD applications, keeping the whole procedural with a high precision.
