About the Lab
Professor In Kwon Lee's research lab specializes in computational geometry, animation synthesis, and motion modeling, with a focus on creating realistic and stylized digital characters and surfaces from real-world data. The lab develops innovative algorithms for reconstructing pipe and canal surfaces from point clouds, enabling applications in 3D modeling and medical imaging. It also pioneers techniques for transforming motion capture data into cartoon-like, exaggerated animations using trajectory-based exaggeration and mass-spring simulations, achieving real-time performance. Additionally, the lab explores facial caricature generation through 3D face modeling and 2D exaggeration, blending computer graphics with artistic expression.

15We present a method to reconstruct a pipe or a canal surface from a point cloud (a set of unorganized points). A pipe surface is defined by a spine curve and a constant radius of a swept sphere, while a variable radius may be used to define a canal surface. In this paper, by using the shrinking and moving least-squares methods, we reduce a point cloud to a thin curve-like point set which will be approximated to the spine curve of a pipe or canal surface. The distance between a point in the thin
Abstract Motion capture cannot generate cartoon‐style animation directly. We emulate the rubber‐like exaggerations common in traditional character animation as a means of converting motion capture data into cartoon‐like movement. We achieve this using trajectory‐based motion exaggeration while allowing the violation of link‐length constraints. We extend this technique to obtain smooth, rubber‐like motion by dividing the original links into shorter sub‐links and computing the positions of joints
