To provide a method for the construction of a three-dimensional model of a woven fabric to simulate the deformation of a woven fabric in the case of stretching or bending a three-dimensional modeling woven fabric completed by Japanese Patent Application 2005-24609 and provide an apparatus for the construction of a three-dimensional model of a woven fabric.

The three-dimensional model construction method and the three-dimensional model construction apparatus for woven fabric perform recalculation of a fabric structure in the case of deforming a three-dimensionally modeled fabric to a predetermined extension ratio and the recalculated three-dimensional model of the fabric is outputted. The deformation of the fabric can be simulated by the method.
