OBJECT MANIPULATION METHOD, OBJECT MANIPULATION PROGRAM, AND INFORMATION PROCESSING DEVICE

摘要

An object (OB) manipulation method for manipulating, to deform, an object (OB) displayed on a display device executes: a step in which a control device for controlling the display device sets a polyhedron (POL) centering on a discretionary point (P0) inside the object (OB); a step of dividing a space inside the polyhedron (POL) by vectors heading from the center (P0) of the polyhedron (POL) toward peaks (P1-P12) of the polyhedron (POL); a step of determining which one of the divided spaces the peak of the object (OB) is included in; a step of preserving the coefficient of decomposition of a peak (POB) of the object (OB) by three vectors constituting a space that includes the peak (POB) of the object (OB); and a step of deforming the object (OB) in accordance with a deformation manipulation acted on the polyhedron (POL) and displaying the deformed object (OB).
