Methods and systems for performing trackerless image guided soft tissue surgery. For a patient in need of brain surgery, pre-operative preparation for a patient is performed by generating a three-dimensional textured point cloud (TPC) for the patient's scalp surface, and registering the first three-dimensional TPC to a magnetic resonance (MR) model of the brain. During the surgery, an intra-operative cortical surface registration to the MR model is performed for the MR-to-cortical surface alignment.
