Base type for a triangle mesh.
|
|
|
|
Base type for a triangle mesh, parameterized by a mesh kernel. The
|
|
mesh inherits all methods from the kernel class and the
|
|
more general polygonal mesh PolyMeshT. Therefore it provides
|
|
the same types for items, handles, iterators and so on.
|
|
|
|
\param Kernel: template argument for the mesh kernel
|
|
\note You should use the predefined mesh-kernel combinations in
|
|
\ref mesh_types_group
|
|
\see \ref mesh_type

\see OpenMesh::PolyMeshT
