Title: OBJECT-SURFACE CORRECTING METHOD, AND PROCESSING METHOD AND PROCESSING SYSTEM FOR WORKPIECE
Abstract:
In the present invention: a plurality of meshes are defined on an object surface; the luminance of the object surface when the object surface is viewed from a viewpoint position is calculated for each of the plurality of meshes on the basis of data concerning a processed shape, a surface roughness curve, the viewpoint position, the direction, angle distribution, and intensity of incident light onto the object surface, and a reflectance and scattering characteristics for each wavelength on the object surface; the shape of the object surface is displayed on the basis of the luminances; and data concerning at least the object shape or the surface roughness curve is corrected so as to obtain a desired appearance of the object surface.
