subscript(_:)
Provides an array of vertex indices that respresents the geometric primitive at the subscripted index.
Declaration
@nonobjc subscript(index: Int) -> [Int32] { get }Discussion
This subscript operates on geometry elements of type Int32 with 4 bytesPerIndex. In the case of the faces property, this operator returns an array of size 3. The contents of the array are vertex indices that compose a triangle primitive, which represents the face identified by the argument face index.
