Abstract
A three-dimensional graphic processing apparatus includes n arithmetic ICs (Integrated Circuits) for performing linear interpolation calculations for each scan line of a triangle polygon to obtain intensity values and depth coordinate values of pixels, and two types of n memories for storing the calculation results. The n arithmetic ICs parallelly execute linear interpolation calculations of n different pixels successive on a single scan line of a single triangle polygon in one processing cycle. Each arithmetic IC calculates for each of every n pixels in one processing cycle, and a corresponding one of the memories stores the calculation result.
