1. An image rendering device for realizing stereoscopic viewing of composite images generated by compositing background three-dimensional models and foreground three-dimensional models each defined in three-dimensional modeling space, the image rendering device comprising:

  • a coordinate converter that performs a coordinate conversion on modeling data defining a geometry of a background three-dimensional model and a geometry of a foreground three-dimensional model, so that coordinates describing vertices of the modeling data are converted into three-dimensional coordinates describing corresponding points in the three-dimensional modeling space;

    a texture mapper that converts background image data into two or more viewpoint textures and maps each viewpoint texture to a background three-dimensional model in the three-dimensional modeling space;

    a viewport converter that extracts, for each of the two or more viewpoint textures, a viewport image from the background three-dimensional model mapped with the viewpoint texture and from the foreground three-dimensional model; and

    a manager that manages the foreground three-dimensional model and the background three-dimensional model, whereinthe two or more viewpoint textures include an intra-texture object, andthe manager determines depth relationship between the foreground three-dimensional model and the intra-texture object, by comparing a parallax of the foreground three-dimensional model occurring in stereoscopic playback with a parallax of the intra-texture object occurring in stereoscopic playback and adjusts positional relationship between the foreground three-dimensional model and the intra-texture object based on a result of the determination.
