【Abstract】 The rendering of Complex scene is important in Virtual Reality System. There are two ways in realizing the virtual scene: 3D graphics and Image based model & rendering. And an image based model & rendering is a novel technique. Based on the theory of perspective projection and three-dimensional transformation, we have gotten a formula which builds the relationship between a reference image and a new image, and releases the demand on a camera, only if the view point is constant, the inner parameter can be restored from the reference images, and the method of estimating parameter is provided. The image in Random direction can be rendered by the formula.更多还原
