We present in the paper a hybrid method for motion editing combining motion blending and Jacobian-based inverse kinematics IK. When the original constraints are changed, a blending-based IK solver is first employed to find an adequate joint ...

We propose an octree-based presentation of vortex particles to simulate smoke and gaseous phenomena in a physical way. Vortex particle method prevails over grid-based method in terms of less numerical dissipation and more detail features, but it suffers ...

While collision avoidance has been the most active topic in pedestrian simulation, the modelling of other kinds of behaviours appears to be essential for better realism. Thus higher cognitive levels of perception and behaviour improve simulation ...

Forward and Backward Reaching Inverse Kinematics FABRIK is a recent iterative inverse kinematics solver that became very popular because of its simplicity, convergence speed and control performance, especially in models with multiple end effectors. In ...

The crucial concept of modeling and synthesis/control of human motion including face and body for animation has been widely studied and explored in the literature. In this regard, the audience's perception of generated or recorded animation scenes is of ...

Three-dimensional human model reconstruction has wide applications due to the rapid development of computer vision. The appearance of cheap depth camera, such as Kinect, opens up new horizons for home-oriented 3D human reconstructions. However, the ...
