PROBLEM TO BE SOLVED: To provide a fuzzy object rendering circuit for continuously and smoothly plotting the image of an object when a view point enters a fuzzy object concerning technique to plot the fuzzy object such as fog, clouds, smoke or flame in computer graphics. SOLUTION: A system for plotting the fuzzy object with a space lattice calculation method includes: a means for distributing a three-dimensional coordinate value by a random number in a grid, performing visual field transformation processing, perspective transformation processing, and view port clip processing at the random number point, and mapping a primitive pattern including a density value to the processed random number point; and a means having a magnification table with a perspective ratio in the visual field transformation as the address of a RAM, storing a primitive pattern size, the number of the random numbers, a plotting size, and the density scale value of the fuzzy object in the RAM, and performing optimization to plot the scaling of the object generated when the view point passes the fuzzy object as the image without an alias.
