Claim 28:
29. A method of determining a location for a surgical procedure, utilizing:
providing a 3D spatial mapping device, wherein the 3D spatial mapping device is configured to map a bone,
attaching a marker configured to be attached to a distal end portion of the bone, wherein the marker includes a QR code, and wherein the distal end section of the bone is visually exposed, and wherein a plurality of markers are attached to the bone;
capturing a plurality of images of the marker and the bone as the bone is being moved, wherein the images include bone data representing a surface map of the bone and marker data identifying a position of the marker relative to the bone and 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 about a pivot point, or fulcrum, that is not visual exposed at predetermined time intervals during rotation of the bone;
sending the bone data and marker data from the images captured by the 3D spatial mapping device to a computer system;
determining a location and orientation of a mechanical axis of the bone from the marker data and bone data with the computer system, wherein the computer system that receives the data from the images captured by the 3D spatial mapping device and determines a location of a mechanical center of a head of the bone and determines a location of a mechanical axis of the bone;
generating a virtual mechanical axis of the bone with the computer system;
sending the virtual mechanical axis to a mixed reality headset; and
displaying the virtual mechanical axis that visually appears to overlay the bone at the location and in the orientation of the mechanical axis on the mixed reality display.
