IMAGE DRAWING DEVICE FOR DRAWING STEREOSCOPIC IMAGE, IMAGE DRAWING METHOD, AND IMAGE DRAWING PROGRAM

摘要

Provided is an image drawing device which realizes a stereoscopic view of a synthesized image in which a background stereoscopic model in three-dimensional modelling space and a foreground stereoscopic model are synthesized. A texture mapping unit transforms a background image to two or more viewpoint textures and maps the viewpoint textures to a background stereoscopic model in three-dimensional modelling space. A viewport transformation unit executes, for each of the two or more viewpoint textures, processing for drawing a viewport image from the background stereoscopic model to which the viewpoint textures are mapped and from a foreground stereoscopic model. The front-back relationship of the foreground stereoscopic model and an object within the textures is determined by comparison of the parallax of the foreground stereoscopic model during stereoscopic reproduction and the parallax of the object within the textures, and the position of the object within the textures and the position of the foreground stereoscopic model are aligned based on the determination result.
