Exactly.
>From sgLoad3DModel (in SimGear/simgear/scene/model.cxx):
ssgTransform * alignmainmodel = new ssgTransform;
alignmainmodel->addKid(model);
sgMat4 res_matrix;
sgMakeOffsetsMatrix(&res_matrix,
props.getFloatValue("/offsets/heading-deg", 0.0),
props.getFloatValue("/offsets/roll-deg", 0.0),
props.getFloatValue("/offsets/pitch-deg", 0.0),
props.getFloatValue("/offsets/x-m", 0.0),
props.getFloatValue("/offsets/y-m", 0.0),
props.getFloatValue("/offsets/z-m", 0.0));
alignmainmodel->setTransform(res_matrix);
Best,
