1. A computer-implemented method for subject-specific two-dimensional modeling of a subject's vasculature, comprising:
receiving a subject-specific three-dimensional model of the subject's vasculature, wherein the subject-specific three-dimensional model includes one or more centerlines;
determining a two-dimensional viewing plane;
determining a projection of the one or more centerlines of the subject-specific three-dimensional model onto the two-dimensional viewing plane, wherein each of the one or more centerlines of the subject-specific three-dimensional model includes a plurality of discrete points, and wherein determining the projection of the one or more centerlines includes maintaining distances between the plurality of discrete points of respective centerlines of the subject-specific three-dimensional model;
generating one or more meshes around the one or more centerlines; and
generating a two-dimensional image depicting the one or more meshes.
