Tessellation

Mesh approximation of geometry.

Tessellation entities approximate geometry with meshes and can appear in the tessellation base member of any representation item. The base data common to every tessellation entity is retrieved regardless of the entity’s actual type; use A3DEntityGetType() to determine which type it is before parsing the type-specific data. A tessellation for solids and surfaces is built from per-face records; a tessellation for 3D wireframes and a tessellation for markups also exist.
