Detailed Description

A Cone.

Warning: Surfaces are reference counted, so only ReferenceCountingPointer should be used to point to them. For this reason, they should be using the static build() method. (The normal constructors will become private in the future).

◆ Cone() [2/2]

Cone::Cone	(	const PositionType &	pos,
		const RotationType &	rot,
		const PositionType &	vert,

Do not use this constructor directly; use the static build method, which returns a ReferenceCountingPointer. This constructor will soon become private

◆ build()

static ConePointer Cone::build	(	const PositionType &	pos,
		const RotationType &	rot,
		const PositionType &	vert,

inlinestatic

Construct a cone with the specified vertex and opening angle. The reference frame is defined by pos and rot; the cone axis is parallel to the local Z axis.

◆ side() [2/2]

Side Cone::side	(	const LocalPoint &	p,
		Scalar	tolerance
	)		const

inlineoverridevirtual

Returns the side of the surface on which the point is. Not defined for 1-sided surfaces (Moebius leaf etc.) For normal 2-sided surfaces the meaning of side is surface type dependent.

Implements Surface.

◆ tangentPlane() [1/2]

ConstReferenceCountingPointer< TangentPlane > Cone::tangentPlane ( const GlobalPoint & ) const

overridevirtual

Tangent plane to surface from global point. Returns a plane, tangent to the Surface at a point. The point must be on the surface. The return type is a ReferenceCountingPointer, so the plane will be deleted automatically when no longer needed.

Implements Surface.
