  self collision
Collision and self collision handling in cloth model dedicated to design garments.
      
Cloth self collision detection was not included to reduce overheads at runtime.
      
For the latter case we can use existing techniques since this corresponds to the usual self collision problem.
      
Improving the quality of the physics simulation and also avoiding self collision detection among vertices of the cloth.
      
  self-collision
But these may well be too general, showing physical anomalies like ?self-collision?, infinite impulsive forces or others.
      
To simulate the behavior of the cloth and its final static appearance on the model, we propose a new collision and self-collision avoidance method to prevent penetration between the cloth and rigid objects and between parts of the cloth.
      
Moreover, the underlying uniform grid makes self-collision detection very efficient.
      
A marginally acceptable animation with self-collision enabled was obtained with t = 0.2s.
      
A self-collision algorithm is also necessary for avoiding fabric to fabric penetration.

This paper presents an experimental procedure to study state-to-state collisional dynamics by using tunable and pulsed laser techniques and timeresolved and dispersed fluorescence method. The decay processes of electronically and vibrationally excited iodine, B3Π0u+(v' = 19), to the adjacent vibrational states in self-collisional events have been directly observed in experiments. The rate constants for the state-to-state vibrational transfer obtained are, kv(19 →18) = (2.21±0.33)×10-11cm3s-1mol-1 and kv(19→...

This paper presents an experimental procedure to study state-to-state collisional dynamics by using tunable and pulsed laser techniques and timeresolved and dispersed fluorescence method. The decay processes of electronically and vibrationally excited iodine, B3Π0u+(v' = 19), to the adjacent vibrational states in self-collisional events have been directly observed in experiments. The rate constants for the state-to-state vibrational transfer obtained are, kv(19 →18) = (2.21±0.33)×10-11cm3s-1mol-1 and kv(19→ 20) = (1.44 ± 0.20) × 10-11cm3s-1mol-l. These results are in satisfactory agreement with the principle of detailed balance. In addition, the collision-free lifetimes and the radiationless quenching rate constants in B(v' = 19) were also obtained in the experiments.
