Detailed Description

Holds a solid representation of a convex body.

Remarks: Administers a convex body. All polygons of the body are convex and planar. Several operations may be applied, ranging from intersection to join where each result it itself a convex body.

Member Function Documentation

◆ _destroyPool()

static void Ogre::ConvexBody::_destroyPool ( )

static

Tear down the internal polygon pool used to minimise allocations.

static void Ogre::ConvexBody::_initialisePool ( )

static

Initialise the internal polygon pool used to minimise allocations.

◆ clip() [1/4]

void Ogre::ConvexBody::clip ( const Frustum & frustum )

Clips the body with a frustum.

The resulting holes are filled with new polygons.

◆ clip() [2/4]

void Ogre::ConvexBody::clip ( const AxisAlignedBox & aab )

Clips the body with an AAB.

The resulting holes are filled with new polygons.

◆ clip() [3/4]

void Ogre::ConvexBody::clip ( const ConvexBody & body )

◆ clip() [4/4]

void Ogre::ConvexBody::clip	(	const Plane &	pl,
		bool	keepNegative = `true`
	)

Clips the object by the positive half space of a plane.

◆ define() [1/3]

void Ogre::ConvexBody::define ( const Frustum & frustum )

Build a new polygon representation from a frustum.

		size_t	vertex
	)		const

Returns a specific vertex of a polygon.

◆ getVertexCount()

size_t Ogre::ConvexBody::getVertexCount ( size_t poly ) const

Returns the number of vertices for a polygon.

◆ hasClosedHull()

bool Ogre::ConvexBody::hasClosedHull ( void ) const

Checks if the body has a closed hull.

◆ logInfo()

void Ogre::ConvexBody::logInfo ( ) const

Log details of this body.

◆ mergePolygons()

void Ogre::ConvexBody::mergePolygons ( void )

Merges all neighboring polygons into one single polygon if they are lay in the same plane.

◆ operator!=()

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

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

◆ reset()

void Ogre::ConvexBody::reset ( void )

Resets the object.
