Mesh Processing refers to the techniques used to manipulate and analyze 3D models represented as a collection of vertices, edges, and faces. This process is essential in fields like computer graphics, computer-aided design (CAD), and 3D printing, where accurate and efficient representation of shapes is crucial. Common operations in Mesh Processing include simplification, where complex meshes are reduced in detail while preserving their overall shape, and smoothing, which helps eliminate noise and irregularities. Other tasks involve mesh generation, where new meshes are created from point clouds or other data, and mesh segmentation, which divides a mesh into meaningful parts for easier analysis.
