Dear all,

Could you suggest me please the ODE equivalent of MathEngine's =
"TransformationMatrix". I would like to determine the position and =
orientation of the objects to be rendered. =20

The definition of "TransformationMatrix" in MathEngine:

    TransformationMatrix
    The transformation matrix of a physical body encodes both its
    orientation and position with no scaling as a 4x4 matrix.
    The behavior for a matrix that includes scaling is undefined.

    Void MeSet(MePhysicalBody body, TransformationMatrix, MeReal =
vector[16]);
    MeReal* MeGet(MePhysicalBody body, TransformationMatrix);

Thank you in advance!

Ivan Tanev
