<p><P>PROBLEM TO BE SOLVED: To provide a deformation simulation method by a boundary element method without causing a waiting time. <P>SOLUTION: This deformation simulation method uses a boundary element method which deforms a virtual object drawn by an operator. The deformation simulation method of a virtual object is provided with: a virtual object drawing stage at which an operator draws a virtual object; a matrix forming stage at which the matrix formation of a boundary element method is carried out during the virtual object drawing stage; an initial boundary condition determination stage at which the initial boundary condition of the virtual object is determined after the virtual object drawing stage has been finished; a boundary condition setting stage at which the boundary condition of a virtual object is set when the operator carries out the operation of deforming the virtual object; a simultaneous equation calculation stage at which the solution of a matrix formed at the matrix forming stage is obtained as a simultaneous equation according to the boundary condition set at the boundary condition setting stage; and a virtual object deformation state drawing stage at which the deformation state of the virtual object is drawn by reflecting the solution obtained at the simultaneous equation calculation stage. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
