Description:
|
Creates a two-dimensional spherical pattern about the
center position, with the pattern seed entity at one pole of the associated sphere. The pattern elements are approximately equally spaced, with the parameter
num_latitudes specifying by default the number of latitudinal rings in the pattern. If
num_latitudes is set to zero, this number is instead determined by the optional
spacing parameter. (This number must be specified if
num_latitudes is zero.) The root position of the pattern is given by root. The pattern coordinates for spacing are specified in the order (longitude, latitude).
|
|
|
Errors:
|
Both the spacing and the number of latitudes is zero.
