Range Images
A range image stores point which are measurements of depth instead of intensity. A valid image point is one in which a range measurement is available. How it is stored is dependent on the data structure but can be checked by calling the function IsValid(). In byte format, 0 is invalid and in vector format, z=-MAXFLOAT is invalid.
Range data is much more complicated than image data. It can be sampled on a regular grid or not, the grid spacings may vary. Together ByteRangeC, FloatRangeC and VectRangeC provide a powerful set of functionality. For accurate results it is important to understand precisely how the system is set up.

Classes:
| Default Classes | Description |
| FloatRangeC | Range image where each pixel is stored using a float. |
| VectRangeC | Range image stored using a vector for each point, ie full |
| ByteRangeC | Range images with one byte per pixel. |
| XYZImage | XYZ Image stuff. |
