Detailed Description

A class for boundaries of a trapzoid.

The trapezoid is assumed to be in the u,v plane (u,v being local coordinates). So w should be relatively small to lie within the boundary. The center of the coordinate system is assumed to be in the center of the trapezoid. Also the trapezoid is supposed to be symmetric around its height. A basic trapezoid would have its bases parallel with v and its height parallel with u. The trapezoid might be rotated around its center.

Constructor & Destructor Documentation

gear::BoundaryTrapezoid::BoundaryTrapezoid ( double  baseBottom, double  baseTop, double  height, double  deltaW, double  alpha  )

inline

Parameters

baseBottom	the length of the bottom base
baseTop	the length of the rectange: v must lie between +- length/2
height	the height of the trapezoid
deltaW	the maximum value of |w| to be within boundary
alpha	how much the trapezoid is rotated around the w axis. (counterclockwise as usual)
