Functionality

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

  • Default - corresponding to spherical coordinates formula

  • Equirectangular

  • Lambert

  • Gall Stereographic

  • NURBS Sphere

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.
