Rendering method and device, game device, and computer-readable recording medium for storing program to render stereo model

Abstract

To make it possible to draw a contour of a stereo model arranged in a virtual space, by a simple processing, a contour drawing model is acquired during initialization (at Step S). This contour drawing model contains a stereo model and has its individual planes reversed from the corresponding planes of the stereo model. In the setting of the state in a virtual space, the contour drawing model is arranged (at Step S). If the contour is to be drawn for the stereo model (at Step S), the contour drawing model is drawn (at Step S). The contour drawing model is perspectively transformed, and only the face with respect to a viewpoint is drawn by erasing a hidden plane. As a result of this hidden plane erasure, the contour drawing model is partially drawn as a contour outside of the stereo model because it is larger than the stereo model. Finally, the stereo model is drawn as usual (at Step S).
