## Function Documentation

## operator<() [1/2]

bool _OgreVolumeExport Ogre::Volume::operator< | ( | const Vector3 & | a,
|  | const Vector3 & | b )

A less operator.

Note
  This operator is needed so that Vertex can serve as the key in a map structrue

Parameters

  a | The first vector to test.
  b | The second vector to test.

## operator==()

bool _OgreVolumeExport Ogre::Volume::operator== | ( | Vertex const & | a,
|  | Vertex const & | b )

== operator for two vertices.

Parameters

  a | The first vertex to test.
  b | The second vertex to test.

## operator<() [2/2]

bool _OgreVolumeExport Ogre::Volume::operator< | ( | const Vertex & | a,
|  | const Vertex & | b )

A less operator.

Note
  This operator is needed so that Vertex can serve as the key in a map structrue

Parameters

  a | The first vertex to test.
  b | The second vertex to test.
