GeometricObjects Interface CATSphere

Usage: an implementation of this interface is supplied and you must use it as is. You should not reimplement it.

interface CATSphere

Interface representing a geometric sphere.

The CATSphere is created by the CreateSphere method of the CATGeoFactory interface and deleted with the Remove method. A sphere is defined by an axis and a radius. The third direction of the axis is the rotation axis. A piece of a full sphere is defined by limiting the meridian and parallel angles. The meridian planes pass through the axis third direction, the parallel planes are orthogonal to the axis third direction. A piece of a sphere is defined by:

Meridian start angle: the low angle value of the meridians. Positive angles are defined by the right-hand rule. Meridian start angle < Meridian end angle. If specified angles are too large, the surface is swept around 2*Pi.
Meridian end angle: the high angle value of the meridians. Positive angles are defined by the right-hand rule. iMeridianStart < iMeridianEnd. If specified angles are too large, the surface is swept around 2*Pi.
Parallel start angle: the low angle value of the parallels. Positive angles are in the direction of the sphere axis. Angles are counted from the radius in the plane defined by the first and second direction of the sphere axis. iParallelStart >= -Pi/2 ; iParallelStart < iParallelEnd
Parallel end angle: the high angle value of the parallels. Positive angles are in the direction of the sphere axis. Angles are counted from the radius in the plane defined by the first and second direction of the sphere axis. iParallelEnd <= Pi/2; iParallelStart < iParallelEnd
