A computer system that provides situational awareness and feedback during a surgical procedure is described. During operation, the computer system generates stereoscopic images at a first 3-dimensional (3D) location in an individual, where the stereoscopic images include image parallax and are based on data having a discrete spatial resolution and a predefined surgical plan for the individual. Then, the computer system provides the stereoscopic images to a display. When a surgical tool is advanced, location information of the surgical tool is updated in the stereoscopic images displayed are updated. Alternatively or additionally, When location information indicates a deviation from the predefined surgical plan during the surgical procedure, the computer system generates revised stereoscopic images that indicate: the deviation has occurred an update to the predefined surgical plan and/or how to return to the predefined surgical plan.
