To preserve the geometric features and details of the original mesh during standardization.

Main Methods:

Fitting mesh vertices and their neighbors to a cubic curve surface using the least squares method.
Employing particle swarm optimization (PSO) within a local surface region to optimize vertex positions for improved triangle quality.
Utilizing a normal angle threshold to selectively adjust vertices, preserving mesh details.

Main Results:

The proposed PSO-based method significantly improves the average triangle quality of the mesh.
Experimental results demonstrate effective preservation of geometric features and fine details.
The method shows superior performance compared to existing triangle mesh standardization techniques.

Conclusions:

The novel PSO-based method offers an effective solution for enhancing triangle mesh quality.
The technique successfully balances mesh standardization with the preservation of original geometric details.
This approach provides a valuable tool for applications requiring high-quality triangle meshes.
