“…Studying surfaces and manifolds is critical for many applications in computer graphics [34,38,41], protein interaction [19,39] and biomedical analysis including cardiac [37,55], brain [14,18,21,22,44,45] imaging, with applications in biophysical and shape modelling [8,20,54], and mapping of cortical organisation [14,22,53]. While the shapes of meshes may vary greatly, ultimately, all problems may be reduced to analysis of functions over tessellated, deformable meshes.…”
