Sphere
The observation sphere may be defined as a full closed sphere or only an spherical sector specified. Multiple concentric spheres (or spherical sectors) may be defined within the same entity. The following parameters are required:
 Name to define the name of this type of observation points. The name must be different of the already defined ones.

Parameters:
 Center Point X, Y and Z coordinates where the sphere will be centered on.

Radius radius of the sphere. A radius sweep may be
defined to generate multiple concentrical spheres.
 Initial Radius radius of the first generated sphere, which is the only one if the sweep is not configured.
 Increment Radius step between two adjacent spheres. It is only considered when the sweep is configured.
 Radius Samples number of concentric spheres to be generated, it must be an integer number. The radius sweep is enabled when this parameter is higher than 1.

Theta Coordinates to set the spherical range where te
observation points are generated, in theta dimension.
 Number of points defines the number of samples to be taken in theta dimension along the specified angular range.
 Initial angle defines the angular angle (in degrees) of the first theta point to be generated.
 Final angle defines the angular angle (in degrees) of the last theta point to be generated.

Phi Coordinates to set the spherical range where te
observation points are generated, in phi dimension.
 Number of points defines the number of samples to be taken in phi dimension along the specified angular range.
 Initial angle defines the angular angle (in degrees) of the first phi point to be generated.
 Final angle defines the angular angle (in degrees) of the last phi point to be generated.
The total number of observation points to be generated in the sphere is ( Radius Samples) x ( Number of Points) _{Theta} x ( Number of Points) _{Phi}.
