Abstract
Provided is image processing technology capable of displaying lines on a field clearly on a screen regardless of the distance to the viewpoint or the visual direction. This image processing method has a step for disposing a linear model formed from multiple polygons in a coordinate system of a three dimensional space based on an image processing program stored in a memory, a step for setting a viewpoint in the coordinate system, a step for performing perspective transformation to the model viewed from the viewpoint, and a step for drawing a linear texture having a prescribed dot width in a frame buffer at a coordinate position after the perspective transformation of the model. The linear texture is drawn on the model in a width of minimum dots regardless of the width occupying the coordinates after the perspective transformation of the model.
