Member Function Documentation

void Ogre::Polygon::deleteVertex

(

size_t

vertex

)

Deletes a specific vertex.

const Vector3& Ogre::Polygon::getNormal

(

void

)

const

Returns the polygon normal.

const Vector3& Ogre::Polygon::getVertex

(

size_t

vertex

)

const

Returns a vertex.

size_t Ogre::Polygon::getVertexCount

(

void

)

const

Vertex count.

void Ogre::Polygon::insertVertex	(	const Vector3 &	vdata,
		size_t	vertexIndex
	)

Inserts a vertex at a specific position.

Note:

Vertices must be coplanar.

void Ogre::Polygon::insertVertex

(

const Vector3 &

vdata

)

Inserts a vertex at the end of the polygon.

Note:

Vertices must be coplanar.

bool Ogre::Polygon::isPointInside

(

const Vector3 &

point

)

const

Determines if a point is inside the polygon.

Remarks:

A point is inside a polygon if it is both on the polygon's plane, and within the polygon's bounds. Polygons are assumed to be convex and planar.

bool Ogre::Polygon::operator!=

(

const Polygon &

rhs

)

const

Determines if the current object is not equal to the compared one.

Definition at line 133 of file OgrePolygon.h.

bool Ogre::Polygon::operator==

(

const Polygon &

rhs

)

const

Determines if the current object is equal to the compared one.

void Ogre::Polygon::removeDuplicates

(

void

)

Removes duplicate vertices from a polygon.

void Ogre::Polygon::reset

(

void

)

Resets the object.

void Ogre::Polygon::setVertex	(	const Vector3 &	vdata,
		size_t	vertexIndex
	)

Sets a specific vertex of a polygon.

Note:

Vertices must be coplanar.

void Ogre::Polygon::storeEdges

(

EdgeMap *

edgeMap

)

const

Stores the edges of the polygon in ccw order.

The vertices are copied so the user has to take the deletion into account.

void Ogre::Polygon::updateNormal

(

void

)

const [protected]

Updates the normal.
