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. Example of usage ---------------- The default parametrization: .. image:: https://user-images.githubusercontent.com/284644/79351826-93169d00-7f52-11ea-99ad-bb904f62ce6c.png
