A body's mass, volume and centre of gravity.
Total mass: the density field integrated over the Solid.
How much space the Solid fills.
The mass-weighted average position.
The three principal moments of inertia, taken about the center of gravity.
A frame at the center of gravity whose axes are the principal axes of inertia.
The estimated relative error of Mass and Volume (0.01 = 1 %); 0 for a mesh, which is measured exactly.
Whether Error is within the Relative error asked for. False when the measuring budget ran out before it was: the numbers are then only as close as Error says.
