Patent ID: 10080963

Abstract:
In an object (OB) manipulation method of manipulating an object (OB) displayed on a display apparatus for deformation, a control apparatus configured to control the display apparatus executes a step of setting a polyhedron (POL) with a given point (P0) in the object (OB) being a center; a step of dividing a space inside the polyhedron (POL) by a vector going from the center (P0) of the polyhedron (POL) to apexes (P1 through P12) of the polyhedron (POL); a step of discriminating in which of the divided spaces an apex of the object (OB) is included; a step of storing a decomposition coefficient of the apex (POB) of the object (OB) by three vectors making up the space including the apex (POB) of the object (OB); and a step of deforming the object (OB) in accordance with the deformation manipulation acted on the polyhedron (POL) and displaying the deformed object (OB).
