Member Function Documentation

distanceToPoint()

double Plane3::distanceToPoint	(	const Coord3 &	,
		bool	wichside = false ) const

Parameters

wichside

if true, the distance along the normal will be returned, wich can be negative.

getProjection()

Coord3 Plane3::getProjection

(

const Coord3 &

pos

)

intersectWith() [1/2]

bool Plane3::intersectWith	(	const Line3 &	,
		Coord3 &	) const

Returns true if the plane intersects with the line. If it returns true, the Coord3 is set

intersectWith() [2/2]

bool Plane3::intersectWith	(	const Plane3 &	,
		Line3 &	) const

Returns true if the planes intersects. If it returns true, the Line3 is set

normal()

Coord3 Plane3::normal ( ) const

inline

onSameSide()

bool Plane3::onSameSide	(	const Coord3 &	p1,
		const Coord3 &	p2 )

Check p1, p2 are on the same side of the plane or not, will return true if one is on the plane.

operator!=()

set() [1/3]

void Plane3::set	(	const Coord3 &	,
		const Coord3 &	,
		const Coord3 &	)

set() [2/3]

void Plane3::set	(	const Coord3 &	vec1,
		const Coord3 &	,
		bool	twovectors )

Parameters

vec1	First vector
twovectors	Specifies if the second argument is a vector or a position

set() [3/3]

float Plane3::set

(

const TypeSet< Coord3 > &

)

Returns

a value between 0-1 that indicates how well the points fit to a plane. 1 = perfect fit 0 = no fit
