Abstract:
1. An apparatus for drawing a stereoscopic image, comprising: a storage unit configured to store coordinate values of an object located in a coordinate space, the coordinate space being represented by a first direction, a second direction and a third direction each different, the coordinate values including first coordinate values along the first direction, second coordinate values along the second direction and third coordinate values along the third direction; a display unit configured to display a stereoscopic image of the object, the stereoscopic image having a parallax along one of the first direction and the second direction; a detection unit configured to detect a direction of the parallax; and a projection operation unit configured to multiply a first projection matrix with the coordinated values of the object when direction of the parallax is the first direction, and multiply a second projection matrix with the coordinate values of the object when the direction of the parallax is the second direction, wherein the first projection matrix subjects the first coordinate values to the parallel projection, and subjects the second coordinate values and the third coordinate values to a perspective projection, the second projection matrix subjects the second coordinate values to the parallel projection and subjects the first coordinate values and the third coordinate values to the prospective projection, the projection operation unit, after multiplying the first projection matrix, subjects the first coordinate values to a perspective multiplication, and the subjects the first coordinate values perspective-multiplied, the second coordinate values and the third coordinate values to the perspective division, and after multiplying the second projection matrix, subjects the second coordinate values to the perspective multiplication, and the subjects the first coordinate values, the second coordinate values perspective-multiplied and the third coordinate values to the perspective division.
