1. A system for determining a location for a surgical procedure, utilizing:
a 3D spatial mapping device, wherein the 3D spatial mapping device is configured to generate map data representative of a three dimensional map a surface of a bone,
a marker configured to be attached to a distal end portion of the bone;
wherein the 3D spatial mapping device is configured to capture a plurality of images of the marker as the bone is rotated in a non-linear path, wherein the images include marker data that identifies a marker location of the marker relative to the three dimensional map data of the surface of the bone;
a computer system that receives the map data and marker data from the images captured by the 3D spatial mapping device and determines a position and orientation of a mechanical axis of the bone relative to the bone;
a mixed reality display, wherein the computer system is configured to send the position and orientation of the mechanical axis to the mixed reality display and the mixed reality display is configured to provide a virtual image of the mechanical axis of the bone that visually appears to overlay the bone at the position and in the orientation of the mechanical axis when viewed with the mixed reality display.
