3D Point

A 3D point is a single measurement of a point in space as an offset from the origin of the measurement system.  In its most basic form this consists of three coordinate measurements (X, Y, and Z) although it is possible to record fewer dimensions by setting any unused coordinates to zero.

In addition to the X, Y and Z coordinates, the C3D format supports additional information stored with each 3D point to describe the coordinate measurement properties – see the descriptions of the Residual and Camera Contribution.
