PROBLEM TO BE SOLVED: To provide a plotting device for three-dimensional graphics for quickly realizing three-dimensional graphics without loading any expensive hardware. SOLUTION: A plotting device for three-dimensional graphics is provided with a three-dimensional data inputting part 21 for inputting three-dimensional data, an arithmetic data kind judging part 32 for judging which of an X value, Y value, and Z value and tone is applied to the three-dimensional data inputted by the three-dimensional data inputting part 21, and a 32 bit×32 bit multiplication processing part 33, a 32 bit×31 bit multiplication processing part 34, and a 32 bit×16 bit multiplication processing part 35 for operating multiplication by changing the number of bits according to the judged result obtained by the arithmetic data kind judging part 32. |
