Detailed Description

Description: Lightweight right circular cone. Use ON_ConeSurface if you need ON_Cone geometry as a virtual ON_Surface.

Constructor & Destructor Documentation

◆ ON_Cone() [1/2]

ON_Cone::ON_Cone ( )

Creates a cone with world XY plane as the base plane, center = (0,0,0), radius = 0.0, height = 0.0.

◆ ON_Cone() [2/2]

ON_Cone::ON_Cone	(	const ON_Plane &	plane,
		double	height,
		double	radius
	)

See ON_Cone::Create.

Member Function Documentation

◆ AngleInDegrees()

double ON_Cone::AngleInDegrees ( ) const

Returns: The angle Iin degrees) between the axis and the side. The angle and the height have the same sign.

◆ AngleInRadians()

double ON_Cone::AngleInRadians ( ) const

Returns: The angle (in radians) between the axis and the side of the cone. The angle and the height have the same sign.

◆ ApexPoint()

const ON_3dPoint& ON_Cone::ApexPoint ( ) const

Returns: Point at the tip of the cone. Remarks: The apex point is plane.origin.

◆ Axis()

const ON_3dVector& ON_Cone::Axis ( ) const

Returns: Unit vector axis of cone.

◆ BasePoint()

ON_3dPoint ON_Cone::BasePoint ( ) const

Returns: Center of base circle. Remarks: The base point is plane.origin + height*plane.zaxis.

◆ CircleAt()

ON_Circle ON_Cone::CircleAt ( double height_parameter ) const

Description: Get iso curve circle at a specified height. Parameters: height_parameter - [in] 0 = apex, height = base

◆ ClosestPointTo() [1/2]

bool ON_Cone::ClosestPointTo	(	ON_3dPoint	point,
		double *	radial_parameter,
		double *	height_parameter
	)		const

returns parameters of point on cone that is closest to given point

◆ ClosestPointTo() [2/2]

ON_3dPoint ON_Cone::ClosestPointTo ( ON_3dPoint ) const

returns point on cone that is closest to given point

◆ Create()

bool ON_Cone::Create	(	const ON_Plane &	plane,
		double	height,
		double	radius
	)

Description: Creates a right circular cone from a plane, height, and radius. plane - [in] The apex of cone is at plane.origin and the axis of the cone is plane.zaxis. height - [in] The center of the base is height*plane.zaxis. radius - [in] tan(cone angle) = radius/height

◆ GetNurbForm()

int ON_Cone::GetNurbForm ( ON_NurbsSurface & ) const

returns: 0 = failure 2 = success

◆ IsValid()

bool ON_Cone::IsValid ( ) const

Returns true if plane is valid, height is not zero, and radius is not zero.

◆ LineAt()

ON_Line ON_Cone::LineAt ( double radial_parameter ) const

Description: Get iso curve line segment at a specified angle. Parameters: radial_parameter - [in] (in radians) 0.0 to 2.0*ON_PI

◆ NormalAt()

ON_3dVector ON_Cone::NormalAt	(	double	radial_parameter,
		double	height_parameter
	)		const

Parameters: radial_parameter - [in] (in radians) 0.0 to 2.0*ON_PI height_parameter - [in] 0 = apex, height = base Remarks: If radius>0 and height>0, then the normal points "out" when height_parameter >= 0.

◆ PointAt()

ON_3dPoint ON_Cone::PointAt	(	double	radial_parameter,
		double	height_parameter
	)		const

evaluate parameters and return point Parameters: radial_parameter - [in] 0.0 to 2.0*ON_PI height_parameter - [in] 0 = apex, height = base

◆ RevSurfaceForm()

ON_RevSurface* ON_Cone::RevSurfaceForm ( ON_RevSurface * srf = nullptr ) const

Description: Creates a surface of revolution definition of the cylinder. Parameters: srf - [in] if not nullptr, then this srf is used. Result: A surface of revolution or nullptr if the cylinder is not valid or is infinite.

bool ON_Cone::Rotate	(	double	angle_in_radians,
		const ON_3dVector &	axis_of_rotation
	)

◆ Rotate() [2/4]

bool ON_Cone::Rotate	(	double	angle_in_radians,
		const ON_3dVector &	axis_of_rotation,
