Abstract

A system for surgical navigation includes a surgical tool, a tracking device configured to track poses of the surgical tool relative to an anatomical object, and a computer. The computer is programmed to perform a constructive sold geometry (CSG) operation using a model of the anatomical object and an accumulation of the tracked poses of the surgical tool relative to the anatomical object and generate a 2D image based on a result of the CSG operation and a viewpoint of a virtual camera by shading fragments of the 2D image based on the result of the CSG operation and the viewpoint of the virtual camera. The CSG operation is independent of the viewpoint of the virtual camera.
