Hello, world! I am a Ph.D. student at KAIST Visual MediaLab, advised by Prof. . My research interests lie in computer graphics and character animation, including generation, editing, in-betweening, retargeting, rigging, and all the fun stuff that makes characters move.

Projects

A python library for motion data processing with nice-looking visualization using OpenGL. It provides several functionalities not only motion-related functions (e.g. forward kinematics) but also auxiliary functions such as rotation conversion, file I/O, visualization with skinned mesh, and more. Most of my research projects have utilized this library for data processing and visualization.
