  Triangular meshes are a widely used representation in the field of 3D
modeling. In this paper, we present a novel approach for edge length-based
linear subdivision on triangular meshes, along with two auxiliary techniques.
We conduct a comprehensive comparison of different subdivision methods in terms
of computational capabilities and mesh-enhancing abilities. Our proposed
approach demonstrates improved computational efficiency and generates fewer
elements with higher quality compared to existing methods. The improvement in
computational efficiency and mesh augmentation capability of our method is
further enhanced when working with the two auxiliary techniques presented in
this paper. Our novel strategy represents a significant contribution to the
field and has important implications for local mesh refinement, computer-aided
design, and isotropic remeshing.
