 // Helper functions to read data from the FloatBuffer. The FloatBuffer is accessed with an offset and an index.
 // The offset holds the initial offset within the FloatBuffer, and the index is a sub-index, which increments with each property that is being read.
 // The data needs to be read in the same order as it is allocated on the host.
