Detailed Description

template<class Kernel>
class OpenMesh::TriMeshT< Kernel >

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.

Parameters:
Kernel,:template argument for the mesh kernel
Note:
You should use the predefined mesh-kernel combinations in Predefined Mesh Types
