3D Data

The C3D file format was created to provide a standard method of storing 3D data as coordinates, referenced to a single origin.  All 3D data locations consist of three dimensions, recording the X, Y and Z distance from a single fixed origin that is used to define the recording environment co-ordinate system.  Typically the +Z axis rises vertically from the floor with the direction of progression for motion within the co-ordinate system in the X and Y axes but this is only a convention.
