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.
