Instance Method

element(at:)

Returns the geometry element at a specified index.

Declaration

func element(at elementIndex: Int) -> SCNGeometryElement

Parameters

elementIndex

The index of the geometry element.

Return Value

A geometry element.

Discussion

Each SCNGeometryElement object describes how vertices from the geometry’s sources are combined into polygons to create the geometry’s shape. Visible geometries contain at least one element.
