    • A methodology for virtual human animation 

      FRANCISCO ALEJANDRO MADERA RAMIREZ; CARLOS GASPAR HERRERA ZAPATA; FRANCISCO JOSE MOO MENA
      We propose a method to animate a 3D virtual human generating keyframes of the model and interpolating to achieve a realistic animation. The first two steps refer to the human modeling, the rigging and the skinning. The ...

    • Self-collision detection in tubular objects approximated by spheres 

      ENRIQUE AYALA FRANCO; FRANCISCO ALEJANDRO MADERA RAMIREZ; FRANCISCO JOSE MOO MENA
      We investigate the performance of an algorithm to detect selfcollisions in a tubular object approximated by spheres. The approach utilizes the Bounding Volume Hierarchy (BVH) to arrange the spheres and it was implemented ...

    • Sphere approximation for non-tubular object 

      FRANCISCO ALEJANDRO MADERA RAMIREZ; FRANCISCO JOSE MOO MENA; ENRIQUE AYALA FRANCO
      We study the problem of approximating a 3D object with a union of overlapping spheres. We employ a disk filled with rays that comes from the center of the disk and points outwards. The disk traverses the object to detect ...
