Detailed Description

surface constructed by revolving a 3D curve about an arbitrary axis

Constructor & Destructor Documentation

Revolution_surface()

hexed::brep::Revolution_surface::Revolution_surface	(	Parametric< 1 > *	generatrix,
		Line_segment	axis,
		double	start_angle = 0,
		double	end_angle = 2 *constants::pi )

Parameters

generatrix	Curve to be revolved. Acquires ownership of generatrix. Need not be coplanar with axis.
axis	Axis about which to revolve generatrix. The length does not matter, but the direction does, because it determines the direction of rotation by the right hand rule. Thus swapping the endpoints reverses the sense of rotation.
start_angle	Same behavior and requirements as for Circular_arc::Circular_arc()
end_angle	Same behavior and requirements as for Circular_arc::Circular_arc()

Member Function Documentation

orig_param_bounds()

Mat< 2, 2 > hexed::brep::Revolution_surface::orig_param_bounds ( ) const

overridevirtual

returns the parameter bounds in the original IGES definition (low, high)

Implements hexed::brep::Parametric< 2 >.

point()

Mat< 3 > hexed::brep::Revolution_surface::point ( Mat< 2 > params ) const

override

param(0) specifies the point on the generatrix. param(1) specifies the angle of rotation such that param(1) = 0. yields start_angle and param(1) = 1. yields end_angle.

rotate()

Mat< 3 > hexed::brep::Revolution_surface::rotate	(	Mat< 3 >	p,
		double	angle ) const

Rotates p about the axis by angle.
