ABSTRACT:
To produce a simulated airbrush spray pattern comprising a random pattern of pixels in a video image, multiple source arrays defining random variations of one or more video image parameters are created. Each time that an airbrush spray pattern is to be generated on a video display, the source arrays are individually retrieved and used to control the characteristics of corresponding pixels in the video image. The arrays are varied on a regular basis to create a random pattern in the image that simulates the effects of an airbrush spray. Various modifications can be used to create particular effects and position dependent textures, such as the short, random streaks that are produced by chalk.
