Abstract

A single-pass, order-independent method in support of rendering transparency effects into a computer generated image is provided. A geometric primitive of a scene is rasterized so as to convert the geometric primitive into a set of pixels. For at least each pixel or subpixel, a stipple pattern is selected from a set of unique stipple patterns. The set of unique stipple patterns is characterized by a select opacity value with the stipple pattern delimiting a unique set of pixels in the computer generated image which contributes to a visible surface determination.
