1. A method comprising:
receiving a plurality of location signals, each received location signal indicative of a respective location of a medical device in an anatomic structure of a patient;
forming a three-dimensional data structure representing locations, within the anatomic structure, visited by the medical device at the locations corresponding to the plurality of location signals;
receiving one or more anchor portions representing locations relative to the anatomic structure;
generating a three-dimensional surface representation of the anatomic structure of the patient based only on the plurality of locations signals and the one or more anchor portions, wherein the three-dimensional surface representation of the anatomic structure of the patient is constrained to contain at least a portion of the three-dimensional data structure, and wherein generating the three-dimensional surface representation of the anatomic structure of the patient includes a volumetric smoothing, and further wherein the volumetric smoothing varies relative to the one or more anchor portions; and
displaying, on a graphical user interface, at least one of a two-dimensional projection of the three-dimensional data structure, the one or more anchor portions, and a two-dimensional projection of the three-dimensional surface representation.
