Geometry
Null – This method returns a Point3 whose X, Y, and Z properties are undefined.
Point3.Null = (NaN, NaN, NaN)
Zero – This method returns a Point3 whose X, Y, and Z properties are all 0.0.
Point3.Zero = (0.0, 0.0, 0.0)
The following public operators are defined for the Point2 and Point3 classes:
- (minus) Operator – Given a pair of points, this operator will compute the vector that
defines the distance between them. The vector contains values for the differences
between the X, Y, and Z properties.
Point3 pt1 = new Point3(10, 20, 30);
Point3 pt2 = new Point3(20, 30, 40);
Vector3 vt = pt1 - pt2;
//vt is (-10,-10,-10)
- (minus) Operator – Given a point and a vector, this operator will compute the point at
the other end of the vector from the input point by subtracting the vector from the point.
Point3 pt = new Point3(20, 30, 40);
Vector3 vt = new Vector3(10, 10, 10);
Point3 pt3 = pt – vt;
//pt3 is (10, 20, 30)
+ Operator – This operation adds the vector to the point to create a new point.
Point3 pt = new Point3(20, 30, 40);
Vector3 vt = new Vector(10, 10, 10);
Point3 pt3 = pt + vt;
//pt3 is (30, 40, 50)
