This data type defines a level in 3-dimensional space. The plane is defined by the position vectors of the 3 points stBasePoint, stSpanPoint1 and stSpanPoint2. These points must not lie on a straight line.
As direction vectors for the parameter representation of the level, the vectors
stDirection1 := stSpanPoint1 - stBasePoint
stDirection2 := stSpanPoint2 - stBasePoint
are used. With the parameters Lambda1 and Lambda2, the parameter equation of the plane then is:
Plane(Lambda1, Lambda2) := stBasePoint + Lambda1 * stDirection1 + Lambda2 * stDirection2
