MeshObject< MeshT, objectDataType >::MeshObject ( SeparatorNode *  _rootNode  )  [inline]

constructor

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 )
