Abstract
A 3D object graphics display device for storing information about 3D objects such as works of art or buildings, and for displaying them on a 2D display. The "3D shape data" and "texture data" of a 3D object is stored in a memory in advance. When an operator operates a manipulator, a 2D image is generated, which would be acquired when the 3D object is seen from a viewpoint indicated by the manipulator, by using the 3D shape data and the texture data in every 1/60 sec or less interval (that is, a minimum display interval of the display device). The 2D image is shown on the display, giving the operator a virtual-reality-like feeling as if he was actually holding the 3D object.
