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.

void Ogre::ConvexBody::clip

(

const ConvexBody &

body

)

Clips the body with another body.

clip() [3/4]

void Ogre::ConvexBody::clip

(

const Frustum &

frustum

)

Clips the body with a frustum.

The resulting holes are filled with new polygons.

clip() [4/4]

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

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

inline

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

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

(

)

Resets the object.
