Direction3 objects. The following section details the constructors, properties, and
methods available using Line3 as example.
Each line type has multiple constructors. The following examples use the Line3 class
constructors.
Here is construction from two points.
// Define points for the line
Point3 first = new Point3(10.0, 10.0, 10.0);
Point3 last = new Point3(20.0, 20.0, 20.0);
// Create the line
Line3 myLine = new Line3(first, last);
This is construction from a point and a direction.
Point3 point = new Point3(10.0, 20.0, 40.0);
Direction3 direction = new Direction3(10.0, 10.0, 0.0);
public Line3 (point, direction);
Use a copy constructor to create a copy of an existing Line.
Line3 anotherLine = new Line3( myLine );
The public properties for the line classes include (Line3 for example):
IsDegenerate - This property returns true if the line is degenerated to a point, i.e. if
the direction of the line is Direction2.Zero.
Point3 p1 = new Point3(10,10,10);
Line3 l1 = new Line3(p1, p1);
bool result = l1.IsDegenerate;
//result is true
Direction3 d1 = new Direction3(5,5,5);
Line3 l2 = new Line3(p1,d1);
result = l2.IsDegenerate;
//result is false
