Detailed Description

template<class MeshT>
class MeshObject< MeshT >

This class provides the functionality for all kind of meshes for the framework

Definition at line 95 of file MeshObjectT.hh.

Constructor & Destructor Documentation

template<class MeshT >
MeshObject< MeshT >::MeshObject ( const MeshObject< MeshT > &  _object  ) 

copy constructor

Create a copy of this object

Definition at line 68 of file MeshObjectT.cc.

References BaseObjectData::init(), BaseObject::name(), and MeshObject< MeshT >::setName().

template<class MeshT >
MeshObject< MeshT >::MeshObject ( DataType  _typeId  ) 

Constructor.

This is the standard constructor for MeshObjects. As triangle and Poly Meshes are handled by this class, the typeId is passed to the MeshObject to specify it.

Parameters:
_typeId This is the type Id the Object will use. Should be typeId("TriangleMesh") or typeId("PolyMesh")

Constructor for Mesh Objects. This object class gets a Separator Node giving the root node to which it should be connected. The mesh is generated internally and all nodes for visualization will be added below the scenegraph node.
You dont need to create an object of this type manually. Use PluginFunctions::addTriMesh or PluginFunctions::addPolyMesh instead. The objectDataType has to match the one of MeshT ( see Types.hh::DataType )
