Abstract: A method generates a three dimensional representation of a garment and comprises: obtaining a three dimensional human body model comprising an outer surface representative of an outermost surface of a human body; obtaining a three dimensional representation of a garment; and simulating a three dimensional physical interaction of the three dimensional body model with a three dimensional representation of the garment. Simulating the three-dimensional physical interaction comprises: deforming both the three-dimensional body model and the three dimensional representation of the garment; and displaying the deformed three-dimensional human body model and the deformed three-dimensional representation of the garment.

Abstract: A method that simulates a response of a target person to one or more simulation inputs comprises: contacting a body of a first test subject with a force-sensing probe; measuring a first force applied by the probe to the body of the first test subject; obtaining a first relative movement comprising a first movement of the probe relative to the body of the first test subject; determining one or more model parameters associated with the body of the first test subject based on the measured first force and the first relative movement; incorporating the one or more model parameters into a target model of at least a portion of a body of a target person; obtaining a simulation input for application to the target model; and simulating a response of the target person in response to the simulation input using the target model.

Abstract: A computer-implemented method simulates a shape of a musculoskeletal system comprising a skeletal subsystem and a soft-tissue subsystem. The method comprises: simulating, by the computer system, an evolution of a skeletal subsystem model over a series of time steps to thereby determine rigid body variables representative of the shapes of the one or more rigid bodies in a physical space at each time step; and simulating, by the computer system, an evolution of a soft-tissue subsystem model over the series of time steps to thereby determine, for each of the one or more soft tissue objects, a soft-tissue object representation in an Eulerian space and an associated Eulerian representation for each vertex in the Eulerian space at each time step, the associated Eulerian representation, for each vertex and for each time step, specifying which one or more material space coordinates for the soft-tissue object correspond to the vertex at the time step.
