1. A method for supporting medical interventions using an augmented reality system, comprising:
determining, using a position marker and an electronic tracking system of the augmented reality system, positions of a set of points, wherein at least one point of the set of points is an attachment point of a pedicle screw;
calculating a template of a shape of a rod for stabilizing bones of a vertebrae using the determined positions of the set of points wherein the template of a shape of a rod comprises the determined positions of the set of points; and
displaying, on an optical head mounted display of the augmented reality system, the calculated template of a shape of a rod in the field of view of a bearer of the optical head mounted display,
wherein the calculated template is displayed in a size that corresponds to a size of the rod at a distance between 1 cm and 100 cm from the optical head mounted display.
