The simulation of elastic human body deformation and the garment pressure distribution
when wearing tight-fitting clothing is critical for the biomechanical design of functional
apparel products. In this paper, we propose a new geometric interpolatory volumetric
subdivision scheme over the hexahedron lattice to simulate the deformation of an elastic
human body and the distribution of garment pressures. The displacement of the initial
coarsest lattice of the deformed elastic human body is calculated by the iterative integration
of the Lagrangian dynamic equation, which reflects the interactive reactions between the
fabric and the elastic human body. The subsequent refined lattices after the deformation of
initial and coarsest lattice of the human body are computed using the volumetric
interpolatory subdivision scheme and eventually generate a continuous solid human body in
the limit. The distribution of garment pressures is also calculated after the deformation of the
elastic human body in this paper. In addition to the geometrical characteristics, we assign
material and physical properties to the control vertices of the volume lattices; for example,
the displacement of initial lattices of the deformed human body in this paper, and apply the
same subdivision rules on the control lattices to acquire smoothly interpolated properties.
This scheme is a potential method for both the dynamic and static volume modeling, and it
can also be utilized in a wide range of applications.
