Abstract
A method of computer visualization of removal of material from an object by a tool during a procedure includes tracking poses of the tool as the tool removes material from the object, performing a constructive solid geometry (CSG) operation using a model of the object, a plan for the removal of the material from the object, and an accumulation of the tracked poses of the tool, generating a two dimensional image of the object based on a result of the CSG operation, and handling movement of the tool by updating the two dimensional image via an update of only a changed sub-volume of the accumulation of the tracked poses.
