Research Summary

My research has focused primarily on the field of computer graphics in general and geometric modeling and processing in particular. Geometric modeling is one of the principal tasks involved in creating and rendering three-dimensional scenes. With an ever-increasing demand for realism, detailed 3D geometric models are becoming commonplace, particularly in computer aided design, manufacturing and many graphics-applied fields such as movie and video game industries. Despite the ubiquity of 3D scanners, most 3D geometric shapes are created through user input, either by modeling from scratch or by editing existing models. However, most commercial modeling systems are still very cumbersome to use and thus often limited to a small group of professional digital artists. Instead, one of my research goals is to make 3D shape modeling and editing simple and intuitive to use, making it accessible for non-expert users. To achieve this, I try to strike a a balance between the control intuitiveness of tools and the geometric complexity of modeling output, thus making the modeling process significantly less labor-intensive.

Below I give an overview of my recent research activities. Please check out further details at my publication page.
