Mesh optimization

Definition

Mesh optimization is the process of improving the quality and efficiency of a 3D model's mesh, ensuring that it has the appropriate level of detail for various applications like 3D printing and simulations. By refining mesh density and topology, mesh optimization helps in reducing file size, improving rendering speed, and enhancing the overall performance of computer-aided design software. This process is crucial for achieving high-quality outputs while minimizing potential issues during manufacturing.
