A mesh is a connected or disconnected collection of vertices and polygon faces that approximates the surface of a 3D object.
- Elements
- Vertices, edges, faces
- Render primitive
- Usually triangles
- Surface direction
- Normals
- Texture coordinates
- UVs
Quality is contextual
A high triangle count can preserve scan detail but hurt web delivery. A low count can be efficient but lose silhouette detail. Judge density where it affects the intended view.
Generated meshes need a hidden-side review
Inspect the back and underside, then check normals, disconnected shells, thin structures, and intersections before rigging, printing, or simulation.
