An Extension fo Seam Pucker Simulation to Manage Collisions

抄録

The seam pucker simulation was extended to be able to treat collisions. In case of seam pucker simulation, an element of one virtual fabric might not collide with the remote portion of another virtual fabric. The local search of collisions is enough for the purpose of seam pucker simulation. For the detection of collisions, “selection” which is one of the functions of a graphic library was utilized. Collisions were settled that the colliding elements were made to contact with each other. Two ways of collision management were proposed. One was the iterated use of “selection” and the other was the geometrical calculation. To utilize for the calculation of deformation, the force from one fabric to another through the contact point was calculated. A test simulation of seam pucker was executed. Another test simulation of an elastic cube wrapped with a fabric was also executed and the proposed collision management was verified.
