1. A method for generating a three-dimensional model of a structure based on at least one two-dimensional image of the structure, comprising: obtaining a generic or statistically-based three-dimensional model of the structure; determining at least one image feature from the at least one two-dimensional image; determining an orientation of the generic or statistically-based three-dimensional model of the structure relative to the at least one two-dimensional image of the structure, wherein the determined orientation provides at least one image feature of a two-dimensional projection of the three-dimensional model that matches the at least one two-dimensional image feature; and after determining the orientation of the generic or statistically-based three-dimensional model, morphing a form or shape of the generic or statistically-based three-dimensional model to fit the at least one two-dimensional image.
