Enumerant Notes

SE_GEOM_CTR_CODE_CENTRE_OF_BUOYANCY

 For a <Geometric Centre> instance A that is a component of an
 <Aggregate Geometry> instance representing a "body" B, the
 <Location 3D> instance specified by A represents the centre of
 buoyancy of B - a point where, if B is partly or
 wholly immersed in a fluid, A is a point where the
 force equal to the weight of the fluid displaced by B
 acts upon B.

SE_GEOM_CTR_CODE_CENTRE_OF_MASS

 For a <Geometric Centre> instance A that is a component of an
 <Aggregate Geometry> instance representing a "body" B, the
 <Location 3D> instance specified by A represents the centre of
 mass of B - a point where the mass of B can be
 considered to be concentrated when analyzing B's motion.

SE_GEOM_CTR_CODE_CENTRE_OF_PRESSURE

 For a <Geometric Centre> instance A that is a component of an
 <Aggregate Geometry> instance representing a "body" B, the
 <Location 3D> instance specified by A represents the centre of
 pressure of B - a point where all the aerodynamic forces
 acting upon B can be considered to act when analyzing
 the motion of B.
