Instance Property


The offset, in bytes, from the beginning of the data to the first vector component to be used in the geometry source.


var dataOffset: Int { get }


You can use the SCNGeometrySource and SCNGeometrySource parameters can together to interleave data for multiple geometry sources in the same array, improving rendering performance. See SCNGeometrySource for details.
