Title:
IMAGE SYNTHESIZER AND APPARATUS FOR PLAYING GAME USING THE IMAGE SYNTHESIZER
Document Type and Number:
WIPO Patent Application WO/1994/029813
Kind Code:
A1
Abstract:
An image synthesizer capable of displaying an image of a three-dimensional object with a small number of polygons in real time with a high resolution. The information about a three-dimensional object is stored in an object data storage (26) as object information for displaying the object using a plurality of shape models of different accuracies. The object information accuracy of shape modles is higher as the distance between the viewpoint of a viewpoint coordinate system and the three-dimensional object is shorter. The texture information attached to the polygons of the shapes is stored in a texture information storage (32) as image information having different resolutions according to the shape models and the polygons constituting the shape models. An image forming part (34) synthesizes an image to be displayed by mapping the texture information of accuracies corresponding to the polygons of a three-dimensional object on the polygons of the object generated by a three-dimensional arithmetic part (22) by transformation of perspective projection, and displays it on the display (40).
