Transforming polygonal mesh by sub-polychord collapse
First Claim
1. A method, comprising:
- identifying, among a plurality of sub-polychords of a given size in a polychord mesh, a seed sub-polychord having a minimal value of a metric associated with collapsing the respective sub-polychord;
identifying, by a processing device, a first test value of the metric for a first test sub-polychord comprising the seed sub-polychord and a first adjacent edge;
identifying a second test value of the metric for a second test sub-polychord comprising the seed sub-polychord and a second adjacent edge;
responsive to determining that 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; and
utilizing the polychord mesh for creating computer-generated imagery.

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.

6. A method, comprising:
-
identifying, by a processing device, a plurality of sub-polychords in a polychord mesh comprising one or more polychords; identifying, among the plurality of sub-polychords, a candidate sub-polychord having an optimal value of a metric associated with collapsing the respective sub-polychord, wherein the optimal value is provided by one of;
a maximal value of the metric among a plurality of values of the metric associated with the plurality of sub-polychords or a minimal value of the metric among the plurality of values of the metric associated with the plurality of sub-polychords;collapsing the candidate sub-polychord by replacing a set of edges comprised by the candidate sub-polychord with a set of vertices, wherein collapsing the candidate sub-polychord further comprises replacing a quadrangle face at an end of the sub-polychord with a triangle; and utilizing the polychord mesh for creating computer-generated imagery. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18)
