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.
