About

Xiao‐Diao Chen is a researcher whose work lies at the intersection of computational geometry and geometric modeling, with a particular focus on distance computation and shape analysis. His most influential contribution is a method for computing the minimum distance between a point and a clamped B-spline surface, a fundamental problem in computer-aided design and robotics that has garnered 21 citations. He extended this work to handle implicit algebraic surfaces, developing algorithms for computing minimum distances between such surfaces, which has been cited 19 times. Chen also introduced a competition flow method for computing the medial axis transform, a key tool for shape representation and analysis, and has recently explored improving ellipse fitting through multi-scale smoothing and key-point searching. His work is notable for its practical impact on geometric processing tasks, providing efficient and robust solutions to core problems. With a career spanning from 2006 to 2024, Chen’s research continues to influence fields such as computer graphics, CAD/CAM, and computational geometry, making him a valuable contributor to the mathematical foundations of shape computation.
