Enumeration

SCNCullMode

The modes SceneKit uses to determine which polygons to render in a surface, used by the cullMode property.

Declaration

enum SCNCullMode : Int

Overview

The vertex data and normal vectors in a geometry designate which side of each polygon is to be considered its front face, and the geometry’s orientation with respect to the camera determines which front surfaces are currently visible. Typically, back-facing surfaces are found only on the interior of a closed geometry, obscured by front-facing surfaces, so rendering these surfaces has a performance cost but no visible effect.
