Here are the data structures with brief descriptions:

[detail level 123]

▼Noctomap	Tables used by the Marching Cubes Algorithm The tables are from Paul Bourke's web page http://paulbourke.net/geometry/polygonise/ Used with permission here under BSD license
CAbstractOccupancyOcTree	Interface class for all octree types that store occupancy
CAbstractOcTree	This abstract class is an interface to all octrees and provides a factory design pattern for readin and writing all kinds of OcTrees to files (see read())
CAbstractOcTreeNode
▼CColorOcTree
CStaticMemberInitializer	Static member object which ensures that this OcTree's prototype ends up in the classIDMapping only once
▼CColorOcTreeNode
CColor
▼CCountingOcTree	An AbstractOcTree which stores an internal counter per node / volume
CStaticMemberInitializer	Static member object which ensures that this OcTree's prototype ends up in the classIDMapping only once
CCountingOcTreeNode	An Octree-node which stores an internal counter per node / volume
CKeyRay
CMapCollection
CMapNode
COccupancyOcTreeBase	Base implementation for Occupancy Octrees (e.g
▼COcTree	Octomap main map data structure, stores 3D occupancy grid map in an OcTree
CStaticMemberInitializer	Static member object which ensures that this OcTree's prototype ends up in the classIDMapping only once
COcTreeBase
COcTreeBaseImpl	OcTree base class, to be used with with any kind of OcTreeDataNode
COcTreeDataNode	Basic node in the OcTree that can hold arbitrary data of type T in value
▼COcTreeKey	OcTreeKey is a container class for internal key addressing
CKeyHash	Provides a hash function on Keys
COcTreeNode	Nodes to be used in OcTree
COcTreeNodeStamped
▼COcTreeStamped
CStaticMemberInitializer	Static member object which ensures that this OcTree's prototype ends up in the classIDMapping only once
CPointcloud	A collection of 3D coordinates (point3d), which are regarded as endpoints of a 3D laser scan
CScanEdge	A connection between two ScanNodes
CScanGraph	A ScanGraph is a collection of ScanNodes, connected by ScanEdges
CScanNode	A 3D scan as Pointcloud, performed from a Pose6D
▼Noctomath
CPose6D	This class represents a tree-dimensional pose of an object
CQuaternion	This class represents a Quaternion
CVector3	This class represents a three-dimensional vector
▼Citerator_base	Base class for OcTree iterators
CStackElement	Element on the internal recursion stack of the iterator
Cleaf_bbx_iterator	Bounding-box leaf iterator
Cleaf_iterator	Iterator to iterate over all leafs of the tree
Ctree_iterator	Iterator over the complete tree (inner nodes and leafs)
