Abstract
PURPOSE:To quickly perform the painting-out processing by obtaining variations of the coordinate value in the depth direction and the color intensity when the coordinate value in the horizontal direction is changed on a maximum length scan line by the extent corresponding to one picture element and using them as the variation on an object scan line. CONSTITUTION:When respect to a triangle in a three-dimensional space, variations of the color intensity and the coordinate value in the depth direction when the coordinate value in the horizontal direction is changed on any scan line by the extent corresponding to one picture element are fixed. These variations are obtained in the painting-out object triangle with respect to the maximum length scan line, and these obtained variations are used as variations on the object scan line at the time of painting out respective scan lines. Thus, it is unnecessary to obtain variations of the color intensity and the coordinate value in the depth direction with respect to each scan line, and the painting-out processing speed is increased.
