We depart from earlier work on soap bubbles and foams by noting that their dynamics are naturally described by a Lagrangian vortex sheet model in which circulation is the primary variable. This leads us to derive a novel circulation-preserving surface-only discretization of foam dynamics driven by surface tension on a non-manifold triangle mesh. We represent the surface using a mesh-based multimaterial surface tracker which supports complex bubble topology changes, and evolve the surface according to the ambient air flow induced by a scalar circulation field stored on the mesh. Surface tension forces give rise to a simple update rule for circulation, even at non-manifold Plateau borders, based on a discrete measure of signed scalar mean curvature. We further incorporate vertex constraints to enable the interaction of soap films with wires. The result is a method that is at once simple, robust, and efficient, yet able to capture an array of soap films behaviors including foam rearrangement, catenoid collapse, blowing bubbles, and double bubbles being pulled apart.","lang":"eng"}],"scopus_import":1,"quality_controlled":"1","oa":1,"language":[{"iso":"eng"}],"day":"27","year":"2015","volume":34,"publisher":"ACM","pubrep_id":"608","publication_status":"published","file":[{"file_id":"4867","relation":"main_file","creator":"system","access_level":"open_access","file_name":"IST-2016-608-v1+1_doublebubbles.pdf","checksum":"57b07d78d2d612a8052744b37d4a71fa","date_updated":"2020-07-14T12:45:07Z","content_type":"application/pdf","file_size":8973215,"date_created":"2018-12-12T10:11:14Z"}],"publist_id":"5521","doi":"10.1145/2767003","issue":"4","_id":"1634","article_number":"149","conference":{"start_date":"2015-08-09","location":"Los Angeles, CA, United States","name":"SIGGRAPH: Special Interest Group on Computer Graphics and Interactive Techniques","end_date":"2015-08-13"},"date_updated":"2023-02-23T10:07:42Z"}
