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.

A method for editing a display of multicolored objects exhibited by an interactive refresh buffer raster driven display system comprising the steps of: (a) forming a first concordance of display position and object identity and storing said first concordance in the refresh buffer; (b) forming a second concordance of object identity and color attributes and storing said second concordance in auxiliary memory; (c) position selecting at least one display object and specifying an editing function; and (d) executing the editing function by way of dynamic alteration of those attributes in the second concordance accessed through the position selection and object identity of the first concordance.
