What Is a Mesh Model? Point Cloud vs. Mesh

A mesh turns a point cloud into a continuous surface — here is the difference and when you need each.

Point cloud vs. mesh

A point cloud is discrete measured points. A mesh connects them into a continuous triangulated surface — useful for visualization, 3D printing, and complex organic geometry.

When to use a mesh

Meshes suit sculptural or freeform surfaces; point clouds and BIM suit measured building documentation.
