Geometry
Theta - This property gets 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.
SphericalPoint sp = new SphericalPoint(20, 40, 20);
Angle ang = sp.Theta;
//ang is 1.15
The SphericalPoint defines the public fields:
Null – This method defines an instance that has coordinates that are all undefined.
SphericalPoint sp1 = SphericalPoint.Null;
//sp1 = {(NaN,NaN,NaN)}
Zero - The instance at the origin of the space containing all instances of this type.
public static readonly SphericalPoint Zero = new
SphericalPoint(0.0,0.0,0);
SphericalPoint sp2 = SphericalPoint.Zero;
//sp2 = {(0,0,0)}
SphericalPoint defines the following public operators:
== Operator - This operation compares two SphericalPoint instances for equality.
Returns true if the instances are equal.
The corresponding coordinates of each instance are compared to determine equality. Note
that comparing SphericalPoint.Null to any other instance will return false. This is
to maintain consistency with the behavior of floating point NaN comparison.
SphericalPoint sp1 = new SphericalPoint(20, 40, 20);
SphericalPoint sp2 = new SphericalPoint(20, 40, 20);
bool result = (sp1 == sp2);
//result is true
