Abstract
The description relates to surgical computer systems, including computer program products, and methods for cumulative buffering for surface imaging. A display image is buffered that has been saved from a previous update. A model representing a tool is subtracted from the buffered display image. The subtracted display image is displayed using a CSG technique at a fixed angle. The subtracted display image is saved. This process is repeated so that the displayed image is cumulatively changed with each change in location of the model representing the tool.
