Abstract
A three-dimensional graphics display system jointly uses three-dimensional image representations and two-dimensional image representations, whereby the data processing amount can be effectively reduced. The data structure of the image data used in this system includes (a) three-dimensional polygon data for a three-dimensional object representing a three-dimensional image and (b) two-dimensional image representation data for a two-dimensional image representation object representing a three-dimensional object as a two-dimensional image arranged in a three-dimensional virtual space having two-dimensional image data and a Z-value. Input data is divided, and an object perspective control part determines a perspective order of objects. A rendering process part overlappingly draws objects according to their perspective order, to correctly represent overlap due to perspective representation. Virtual collisions can be rendered by exclusion control of the space areas of all objects. If the data structure includes relational information of all object portions, the data processing amount can be reduced even further.
