ABSTRACT:
If object identity is written into pixel locations of the refresh buffer portion of a raster-driven display as objects are drawn or amended, and if such object identity is used to index color maps and tree-linked lists of multiple object displays, then editing functions, such as correlation and echoing, color mixing, and selective erasure, at the display level can be invoked and executed with a minimum of reprocessing of the display list at the host level.
