This webpage shows softwares I have made in my research. These softwares are made for experimental purpose. If you have any suggestions or comments about them, or if you want to have the source code of these softwares, please send an email to me: qianyizh@usc.edu. Current available softwares are listed bellow :

• MendIT : A sketch-guiding topology editing software for 3D models. It can be also used as a topology noise removal tool.
• TopoMender : A robust efficienct program for removing small handles in 3D models.
• Tsinghua Statue Model : A goddess statue model stanned in Tsinghua University. It is a by-product of the registration project.

Introduction

MendIT is a software designed for topology repair and editing of mesh models. The algorithm of this software is based on Editing The Topology of 3D Models by Sketching appeared in SIGGRAPH 2007.

Briefly speaking, the software contains two major functions: a sketching system and a back-end algorithm. The sketching system let the user draw the desired topology of the model and the back-end algorithm automatically turn the model into the desired topology while preserving most geometry.

*** This program is strongly recommended to run on a NVDIA graphics card ***

Introduction

TopoMender is a software aiming for volume data topology repair, based on Topology Repair of Solid Models Using Skeletons accepted by Trans. Vis. Comput. Graph.

This program reads a volume data file (stored in SOG format, which could be generated from PolyMender software), break or fill the handles under a given size, and then generate a polygonal mesh stored in PLY format. This program is both robust and efficient, as it never introduce invalid geometry or additional handles, and consumes a small amount of time and memory space.

Introduction

This model is a by-product of the registration project. We scanned 8 pieces of point cloud from the original statue, with 30~80K points in each piece. A registration algorithm is performed to merge all the 8 pieces into one, from which generated a mesh, and finally we use PolyMender software to get a hole-free mesh model.
