Abstract:
1. An image-based protruded displacement mapping method in a system for representing a shape of an object protruding from a polygonal surface using a three-dimensional object, texture information and displacement information, comprising: an intersection point search step of searching for an intersection point of a surface of a protruding object, defined by the displacement information, and an observer's sight line, and displaying the shape of the protruding object on the polygonal surface; an overflow representation step of adding a separate polygonal surface and representing a shape of the protruding object, corresponding to overflow deviating from a boundary of the polygonal surface, on the added polygonal surface; a steeply inclined surface step of detecting a steeply inclined surface in the shape of the protruding object; and a steeply inclined surface correction step of representing an additional texture on the steeply inclined surface.
