Description

This data structure defines the line segment in 3-dimensional space which starts with the point stStartPoint and ends with the point stEndPoint.

Note: In contrast to a straight line, a line segment has a finite extension, as it does not go beyond the defining points. The points stStartPoint and stEndPoint may also be equal. In this case the line segment reduces to a point.

The following figure illustrates the difference between a straight line and a line segment:
