Member Function Documentation

insertVertex() [1/2]

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

Inserts a vertex at a specific position.

Note

Vertices must be coplanar.

insertVertex() [2/2]

void Ogre::Polygon::insertVertex

(

const Vector3 &

vdata

)

Inserts a vertex at the end of the polygon.

Note

Vertices must be coplanar.

getVertex()

const Vector3& Ogre::Polygon::getVertex

(

size_t

vertex

)

const

Returns a vertex.

setVertex()

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

Sets a specific vertex of a polygon.

Note

Vertices must be coplanar.

removeDuplicates()

void Ogre::Polygon::removeDuplicates

(

void

)

Removes duplicate vertices from a polygon.

getVertexCount()

size_t Ogre::Polygon::getVertexCount

(

void

)

const

Vertex count.

getNormal()

const Vector3& Ogre::Polygon::getNormal

(

void

)

const

Returns the polygon normal.

deleteVertex()

void Ogre::Polygon::deleteVertex

(

size_t

vertex

)

Deletes a specific vertex.

isPointInside()

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.

storeEdges()

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.

reset()

void Ogre::Polygon::reset

(

void

)

Resets the object.

operator==()

bool Ogre::Polygon::operator==

(

const Polygon &

rhs

)

const

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

operator!=()

bool Ogre::Polygon::operator!= ( const Polygon &  rhs ) const

inline

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