/** \class TriMeshT TriMeshT.hh <OpenMesh/Mesh/TriMeshT.hh>

|

|
|
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
