triangleIndices
An array of indices describing the triangle mesh formed by the plane geometry’s vertex data.
Declaration
@nonobjc var triangleIndices: [Int16] { get }Discussion
Each 16-bit integer value in this array represents an index into the vertices and textureCoordinates arrays. Each set of three indices identifies the vertices that form a single triangle in the mesh. You can use array as an index buffer for a triangle mesh in GPU-based rendering or to create 3D model asset files.
Each set of three indices forms a triangle, so the number of indices in the triangleIndices array is three times the triangleCount value.
