% Compute force and torque for a CAD model.
Shadowing is not modeled. Vertices must be entered into faces
counterclockwise. The axis of rotation for the fuselage should be
[0;0;0]; Plots will be against whichever input, alpha or beta, changes
the most.
Lift and drag are assumed to be in the x-z plane. Drag is opposite
the velocity vector. Lift is normal to drag in the x-z plane.
