Geometry
The SphericalPoint class provides a constructor that creates the point from two
angles and the distance from the origin. Here is construction by the theta, phi, and rho
spherical polar coordinates, where:
theta - The angle between the X axis and the line, which is the projection onto the XY
plane of the line of shortest distance connecting the origin of 3D space with the point.
phi - The angle between the XY plane and the line of shortest distance connecting the
origin of 3D space with the point.
rho - The length of the line of shortest distance connecting the origin of 3D space with
the point.
Angle theta = new Angle(0.5);
Angle phi = new Angle(1.0);
double rho = 10.0;
SphericalPoint sp = new SphericalPoint(theta, phi, rho);
Here is the copy constructor that creates a copy of an existing SphericalPoint:
SphericalPoint myPt = new SphericalPoint(SphericalPoint sp);
The public properties for SphericalPoint include:
Phi - This property gets the angle between the XY plane and the line of shortest distance
connecting the origin of 3D space with the point.
SphericalPoint sp = new SphericalPoint(20, 40, 20);
Angle ang = sp.Phi;
//ang is 2.3
Rho - This property gets the length of the line of shortest distance connecting the origin of
3D space with the point.
SphericalPoint sp = new SphericalPoint(20, 40, 20);
double distance = sp.Rho;
//distance is 20
