Well, my first suspicion is just that the order of the arguments in
the C++ code is wrong.  main.cxx invokes

    sgMakeRotMat4(rot_matrix, h_rot, p_rot, r_rot);

That matches the prototype in sg.h:

  inline void sgMakeRotMat4   ( sgMat4 dst,const SGfloat h, const SGfloat p, const SGfloat r )

except that a change in p rolls the aircraft 3D model, while a change
in r adjusts the pitch.  PLIB must have a 90-degree rotated view of
the model, assuming that 0 heading is off one of the wingtips.  I'm
not sure how to fix that, but at least the properties look right now.


All the best,


David
