PST FOM Basics

• ECEF coordinates, 64-bit IEEE double precision.

• Using Quaternions to represent orientation.

• Entity motion always sent in motion_t:

  • Position, velocity, acceleration,
  • Orientation, Orientation dot, Orientation dot dot.
  • Facilitates dead-reckoning in SIGs, simulations.

• Point-of-View interaction: motion_t & “handle” obj.

  • Moving POV stays attached to moving entity.
