Abstract:
1. A method of rendering an image, comprising the steps of: mapping first semitransparent texture images respectively onto first polygons which make up a first semitransparent object having at least one three-dimensional shape, the first semitransparent texture images being written into a texture rendering area of an image memory and corresponding to the first semitransparent object; mapping second semitransparent texture images respectively onto second polygons which make up a second semitransparent object having at least one three-dimensional shape, the second semitransparent texture images being written into the texture rendering area and corresponding to the second semitransparent object, and the second semitransparent object being rendered to lap over the first semitransparent object; arbitrarily moving the first and second semitransparent texture images to rewrite them into the texture rendering area, thereby causing said first semitransparent texture images to be associated respectively with different polygons from among said first polygons, and causing said second semitransparent texture images to be associated respectively with different polygons from among said second polygons; and repeating the mapping step of the first semitransparent texture images, the mapping step of the second semitransparent texture images and the arbitrary moving step of the first and second semitransparent texture images, wherein, during said arbitrary moving step, said first semitransparent texture images are associated respectively with different adjacent polygons from among said first polygons in a circulating manner, and said second semitransparent texture images are associated respectively with different adjacent polygons from among said second polygons in a circulating manner.
