Instance Property


A Boolean value specifying whether SceneKit uses a geodesic polygon mesh to render the sphere.


@property(nonatomic, getter=isGeodesic) BOOL geodesic;


The default value is NO, specifying that SceneKit constructs a sphere mesh using a rectangular grid, like the lines of latitude and longitude on a globe of the Earth. This type of sphere mesh is efficient for most uses, but can cause texture distortion in the areas near its poles.

A value of YES specifies that SceneKit constructs a sphere mesh by successively subdividing an icosahedron, creating a grid of uniformly sized triangles across the entire surface of the sphere, as shown below.
