A method of edge loop selection includes accessing a polygon mesh; receiving a selection of a first edge connected to a first non-four-way intersection vertex; receiving, after receiving the selection of the first edge, a selection of a second edge connected to the first non-four-way intersection vertex; in response to receiving a command invoking an edge loop selection process: evaluating a topological relationship between the first edge and the second edge; determining a rule for processing a non-four-way intersection vertex based on the topological relationship between the first edge and the second edge; and completing an edge loop by, from the second edge, processing each respective four-way intersection vertex by choosing a middle edge as a next edge at the respective four-way intersection vertex, and processing each respective non-four-way intersection vertex based on the rule.
