1. A method of performing augmented reality assisted surgery, the method comprising:
generating a virtual scene comprising one or more virtual elements comprising one or more anatomical elements corresponding to one or more anatomy parts of a patient;
acquiring one or more images of an actual physical scene comprising the one or more anatomy parts;
automatically determining, based on the one or more images or another input, a step of a plurality of steps of a surgery the one or more images correspond to;
limiting access to a library of augmentation element options during the step of the surgery to only show a subset of augmentation element options of the library of augmentation element options during the step of the surgery, the subset of augmentation element options corresponding to the step of the plurality of steps of the surgery;
automatically identifying one or more references in the actual physical scene during the surgery;
registering, during the step of the surgery, the virtual scene to the one or more references to generate an augmented scene comprising one or more augmentation elements configured based on one or more augmentation element options selected from the subset of augmentation element options; and
displaying, during the surgery, the augmented scene as an overlay on an anatomy of the patient via a display device.
