PATTERN EMBEDDING PROGRAM, PATTERN EMBEDDING DEVICE, AND PATTERN EMBEDDING METHOD

摘要

A polygon mesh setting unit sets a polygon mesh representing a surface shape of an object in a virtual 3-dimensional space. A polygon specification unit specifies a region where a concealed pattern is to be embedded in the polygon constituting the polygon mesh and specifies the polygon positioned in the specified region as a specific polygon. A direction modification unit modifies the direction of the specific polygon so that the direct reflection direction of the light from the light ray direction is directed to the direction of the visual line.
