DESCRIPTION

       This engine has inputs that specify values for translation, rotation, scale, and center of
       transformation.  As  output,  it  produces a transformation matrix that transforms objects
       into the space specified by the scale, rotation, and translation inputs (in that order).

       The input fields can have multiple values, allowing the engine to compose several matrices
       in  parallel.  Some inputs may have more values than others. In such cases, the last value
       of the shorter inputs will be repeated as necessary.

INPUTS

     SoMFVec3f           translation
          Translation in x, y, and z.

     SoMFRotation        rotation
          Rotation.

     SoMFVec3f           scaleFactor
          Scale factors in x, y, and z.

     SoMFRotation        scaleOrientation
          Rotational space for scaling.

     SoMFVec3f           center
          Center point for scaling and rotating.

OUTPUTS

     (SoMFMatrix)        matrix
          Transformation matrix that transforms from object space into the space specified by the
          inputs.
