Detailed Description

Describes an infinite cylindrical surface. A cylinder is defined by its radius and positioned in space with a coordinate system (a gp_Ax3 object), the "main Axis" of which is the axis of the cylinder. This coordinate system is the "local coordinate system" of the cylinder. Note: when a gp_Cylinder cylinder is converted into a Geom_CylindricalSurface cylinder, some implicit properties of its local coordinate system are used explicitly: - its origin, "X Direction", "Y Direction" and "main Direction" are used directly to define the parametric directions on the cylinder and the origin of the parameters, - its implicit orientation (right-handed or left-handed) gives an orientation (direct or indirect) to the Geom_CylindricalSurface cylinder. See Also gce_MakeCylinder which provides functions for more complex cylinder constructions Geom_CylindricalSurface which provides additional functions for constructing cylinders and works, in particular, with the parametric equations of cylinders gp_Ax3

Constructor & Destructor Documentation

GCylinder.GCylinder

(

)

Creates a indefinite cylinder.

GCylinder.GCylinder	(	GAx3	A3,
		double	Radius
	)

Creates a cylinder of radius Radius, whose axis is the "main Axis" of A3. A3 is the local coordinate system of the cylinder. Raises ConstructionErrord if R < 0.0

Member Function Documentation

GAx1 GCylinder.Axis

(

)

Returns the symmetry axis of the cylinder.

void GCylinder.Coefficients	(	double[]	A1,

		double[]	B3,
		double[]	C1,
		double[]	C2,
		double[]	C3,
		double[]	D
	)

Computes the coefficients of the implicit equation of the quadric in the absolute cartesian coordinate system : A1.X**2 + A2.Y**2 + A3.Z**2 + 2.(B1.X.Y + B2.X.Z + B3.Y.Z) + 2.(C1.X + C2.Y + C3.Z) + D = 0.0

boolean GCylinder.Direct

(

)

Returns true if the local coordinate system of this cylinder is right-handed.

GPnt GCylinder.Location

(

)

Returns the "Location" point of the cylinder.

GCylinder GCylinder.Mirrored

(

GPnt

P

)

Performs the symmetrical transformation of a cylinder with respect to the point P which is the center of the symmetry.

GCylinder GCylinder.Mirrored

(

GAx1

A1

)

Performs the symmetrical transformation of a cylinder with respect to an axis placement which is the axis of the symmetry.

GCylinder GCylinder.Mirrored

(

GAx2

A2

)

Performs the symmetrical transformation of a cylinder with respect to a plane. The axis placement A2 locates the plane of the of the symmetry : (Location, XDirection, YDirection).

GAx3 GCylinder.Position

(

)

Returns the local coordinate system of the cylinder.

double GCylinder.Radius

(

)

Returns the radius of the cylinder.

GCylinder GCylinder.Rotated	(	GAx1	A1,

Rotates a cylinder. A1 is the axis of the rotation. Ang is the angular value of the rotation in radians.

GCylinder GCylinder.Scaled	(	GPnt	P,
		double	S
	)

Scales a cylinder. S is the scaling value. The absolute value of S is used to scale the cylinder

void GCylinder.SetAxis

(
