object, i.e. two values for a Point2 and three values for a Point3. Otherwise an exception is
raised. The Point Operator for Point3 is defined as:
public static explicit operator Point3 ( double[ ] arg );
Given an array containing the values {10, 20, 30}, the Point3 object created will have a
value of 10 for X, 20 for Y, and 30 for Z.
double[] dbArray = new double[] { 10.0, 20.0, 30.0 };
Point3 pt3 = (Point3)dbArray;
//pt3 = (10, 20, 30);
The Point2 and Point3 classes also define a set of public methods for converting
between Cartesian and polar coordinates.
GetCartesianFromPolar – This method computes a Point object in Cartesian
coordinate space from an input of polar coordinates. The Point3 method has the
following definition:
public static void GetCartesianFromPolar(
Angle theta,
Angle phi,
double rho,
out double x,
out double y,
out double z
);
“Theta” is an Angle object that represents the angle in Cartesian space between the X
axis and the line connecting the origin to the point projected onto the XY plane. The
Angle object “phi” represents the angle between the XY plane and the line connecting
the origin to the point. The value “rho” is the length of the line connecting the 3D origin
to the point.
The method has three output parameters: double x, double y, and double z. These
values define the Cartesian coordinate for the point location.
