Abstract
An example method of transforming polygonal meshes by sub-polychord collapse may include identifying, among a plurality of sub-polychords of a given size, a seed sub-polychord having an optimal value of a metric associated with collapsing the respective sub-polychord. The example method may further include identifying a first test value of the metric for a first test sub-polychord comprising the seed sub-polychord and a first adjacent edge, and further identifying a second test value of the metric for a second test sub-polychord comprising the seed sub-polychord and a second adjacent edge. The example method may further include, responsive to determining a minimum of the first test value of the metric and the second test value of the metrics is less than a base value of the metric for the seed sub-polychord, transforming the seed sub-polychord by adding an adjacent edge that produces a test sub-polychord having the minimum test value.
