Triangle meshes can be viewed as graphs, and hence graph-based methods can be applied to meshes. Moreover, the discrete operators obtained using other methods, e.g., the cotangent Laplacian (Section 5.2), can be thought as particular versions of the graph Laplacian with local-geometry-aware ...
In older versions of DALI, an object-oriented API was used to define operations instead of a functional API. The use of the object API is discouraged now and its documentation is shown here for reference purposes.The legacy object “operators” are contained in the dali.ops module and their...
