In this article, a method of generating a pixel in a computer system consisting of the steps of: accessing a first point on a first polygon, determining a first line segment having less than a predetermined error and determining whether a next line segment causes less than the predetermined error.
Abstract
A method of generating a pixel in a computer system. The computer system includes a processor and a memory. The memory includes a first polygon and a texture map. The method comprises the steps of: accessing a first point on a first polygon. A step of determining a first line segment having less than a predetermined error and determining whether a next line segment causes less than the predetermined error. The next line segment is longer than the first line segment in one direction. If the next line segment causes less than the predetermined error, then determine whether a new next line segment causes less than the predetermined error. Otherwise, access a texel in the texture map at a position corresponding to the first point and the first line segment, and generate the pixel from the texel.

Method and apparatus for drawing lines, curves, and points coincident with a surface

TL;DR: In this paper, the authors present a method for rendering objects for display to a viewer upon a display having a plurality of display pixels, which includes the steps of, for a surface to be displayed having a surface marking coincident therewith, (a) moving the surface marking towards the viewer or, alternatively, moving the surfaces away from the viewer, by an amount that is function of a parameter (S) and also a scale factor (K) that expresses a relationship between viewer eye coordinate units and display pixel units.
