Three-dimensional graphic processing apparatus.

摘要

A three-dimensional graphic processing apparatus includes n arithmetic ICs (10A to 10D) 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 (11A to 11D, 12A to 12D) for storing the calculation results. The n arithmetic ICs (10A to 10D) 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 (11A to 11D, 12A to 12D) stores the calculation result.
