Abstract
A texture mapping apparatus for the real-time display of a figure in which an animated image has been mapped. The apparatus includes a device which generates 2D (2 dimensional) source coordinates data which provide a source for texture mapping data corresponding to 3D (3 dimensional) destination coordinates data which in turn provide destinations for texture mapping data. A first dual port memory stores the 2D source coordinates data, and a second dual port memory stores animated image data. The 2D source coordinates data are read out from the first dual port memory to the second dual port memory as destination addresses. Color data read out from the second dual port memory are supplied to a display unit.
