IMAGE QUICK DRAWING DEVICE

摘要

PURPOSE:To give a mass with each area as the unit and to quickly draw an image by dividing a three-dimensional object into primitives which can be quickly drawn and gradually changing the lightness and the chromaticity based on them to draw the image. CONSTITUTION:A primitive generating part 1 which divides the three- dimensional object into prescribed graphics to generate primitives and a gradation drawing part 3 which draws the image while gradually changing the lightness and the chromaticity based on these generated primitives are provided, and the primitive generating part 1 divides the three-dimensional object into prescribed graphics to generate respective primitives in response to the drawing request, and the gradation drawing part 3 draws the image while gradually changing the lightness and the chromaticity based on these primitives.
