Detailed Description

CylindricalSurface CylindricalSurface.hxx cadex/Geom/CylindricalSurface.hxx.

Defines a cylindrical surface.

A cylindrical surface is defined by an axis placement and a radius. The following image depicts a cylindrical surface example:

Cylindrical surface

A cylindrical surface is parametrized as follows: \(\mathbf{S}(u,v) = \mathbf{P} + R\cos(u)\mathbf{X} + R\sin(u)\mathbf{Y} + v\mathbf{Z}\), where

• \(\mathbf{P}\) is an origin point,
• \(\mathbf{X}\), \(\mathbf{Y}\) and \(\mathbf{Z}\) are directions (unit vectors) of X, Y and Z axes respectively,
• \(R\) is a radius,
• \(u\) belongs to \([0, 2\pi]\),
• \(v\) belongs to \((-\infty, +\infty)\).

U-parameter is an angle along the circle at any parameter V and V-parameter is a length along the Dz axis. Thus, U-isolines are lines and V-isoline are circles.

V-isoline at \(v=0\) is a circle of radius \(R\) in the plane defined by an axis placement.

Cylindrical surface is U-periodical with period \(2\pi\).

If a face lying on a cylindrical surface takes full U-period then the boundary wire will contain a seam-edge.
