ABSTRACT:
A high-speed automatic image drawing apparatus divides a three-dimensional object to draw into primitives that can be drawn at a high speed, and draws an image of the object according to the primitives by gradually changing lightness and chromaticity. The image thus provided has a material-like impression. The apparatus comprises a primitive forming unit for dividing the three-dimensional object to draw into predetermined shapes and forming primitives according to the shapes, and a grading unit for drawing the object according to the primitives by gradually changing lightness and chromaticity. In response to a request of drawing a three-dimensional object, the primitive forming unit divides the object into predetermined shapes, and forms primitives for the shapes. Thereafter, the grading unit draws an image of the object according to the primitives by gradually changing lightness and chromaticity.
