Physics based garment simulation systems and methods

A non-transitory computer readable medium having instructions stored thereon for simulating the fitting of a deformable object over one or more time intervals, wherein the instructions, when executed by a processor cause a device to perform operations comprising:

• at each time interval:
• simulating the deformable object's motion based on at least one material property for the deformable object and at least one external parameter, wherein the deformable object is represented as a polygonal mesh;
• detecting at least one collision between the deformable object and at least one environmental object, wherein the at least one environmental object is represented as a polygonal mesh;
• resolving the at least one collision between the deformable object and the at least one environmental object;
• detecting at least one potential collision between the deformable object and at least one kinematic object, and applying a repulsive force to the at least one potential collision, wherein the at least one kinematic object is represented as a polygonal mesh;
• detecting at least one actual collision between the deformable object and the at least one kinematic object and applying a restitution impulse to the at least one actual collision;
• detecting at least one remaining actual collision and resolving the remaining at least one actual collision;
• and
• determining whether the simulation of the deformable object's motion has come to a rest based on a velocity of the deformable object.
