Intrinsic Mollification Schemes to Enhance Cotangent Weights Robustness

The project aims to tackle the challenge of low-quality triangles in triangle meshes by mollifying each triangle, effectively simulating improved edge lengths to eradicate intrinsically thin triangles. The overarching objective is to establish a unified preprocessing step capable of managing such cases, thereby streamlining CGAL's cotangent weight calculation through intrinsic mollification. This endeavor encompasses multiple facets: firstly, the exposure of intrinsic mollification as an independent option for heat method computation; secondly, the implementation and comparison of advanced schemes delineated in recent research to refine intrinsic mollification. Furthermore, the project ultimate goal is to use intrinsic mollification to enhance the outcomes of other CGAL packages such as curvature flow, parameterization, skeletonization, and mesh fairing that use cotangent weights.
