      Grima, C.I.; Márquez, A.; Ortega, L. (Eurographics Association, 2003)
      Motion planning and visibility problems are some of the most important topics studied in Computer Graphics, Computational Geometry and Robotics. There exits several and important results to these problems. We propose a new ...
    • Extending the Immediate Buckling Model to Triangular Meshes for Simulating Complex Clothes 

      Choi, Kwang-Jin; Ko, Hyeong-Seok (Eurographics Association, 2003)
      The immediate buckling model is an essential element for simulating realistic cloth animations without introducing buckling instability. The original model is restricted to structured regular quad meshes, by which its use ...
