ABSTRACT:
A real time texture mapping method produces an image of an object having a surface that has dynamically changing texture by using image data and moving image texture pattern data. The image data is stored in a drawing area of an image memory, and the moving image texture pattern data is stored frame-by-frame in a texture area of the image memory. The moving image texture pattern data stored in the texture area is mapped a frame per vertical display period onto the surface of the object which is represented in the image data stored in the drawing area. The new two-dimensional image data having the texture pattern data mapped on the surface of the object is used as a current image frame for display. The new image data having the texture pattern data mapped on the surface of the object may be stored in the texture area of the image memory, and used as a new texture pattern to map onto a second object stored in the drawing area for a next image frame to be displayed. A video game apparatus implementing this method includes the image memory having a display area as well as the texture area and drawing area. The display area stores image data of the current image frame for display. The drawing and display areas have interchangeable functions.
