Sphere (Surface)

Functionality

This node generates a spherical Surface object. Several parametrizations are available:

• Default - corresponding to spherical coordinates formula

• Equirectangular

• Lambert

• Gall Stereographic

• NURBS Sphere

For formulas, please refer to Wikipedia: https://en.wikipedia.org/wiki/List_of_map_projections

Inputs

This node has the following inputs:

• Center. The center of the sphere. The default value is (0, 0, 0) (origin).

• Radius. Sphere radius. The default value is 1.0.

• Theta1. Theta1 parameter of the Equirectangular projection. This input is only available when the Projection parameter is set to Equirectangular. The default value is pi/4.

Parameters

This node has the following parameter:

• Projection. This defines the parametrization to be used.

Outputs

This node has the following output:

• Surface. The generated spherical surface.
