Abstract:
A three-dimensional graphics display system comprising:a data input part receiving input data comprising: (a) three-dimensional polygon data for a three-dimensional object representing a three dimensional image; and (b) two-dimensional image representation data provided for a two-dimensional image representation object, wherein the two-dimensional image representation object represents a corresponding three-dimensional object as a two-dimensional image arranged in a three-dimensional virtual space, wherein the two-dimensional image representation data comprising (i) two-dimensional image data is defined on an x-y coordinate system and (ii) a Z-value representing a depth within the virtual space; an object perspective control part for determining a perspective order of objects based on the input data; a rendering process part for overlappingly rendering objects, including the tree-dimensional object and the two-dimensional image representation object, in order from a rest object to a nearest object, based on the determined perspective order, to correctly represent overlap due to perspective representation; and an output part for displaying a rendering result; wherein three-dimensional objects and two-dimensional image representation objects are rendered simultaneously in the three-dimensional virtual space.
