DESCRIPTION

       This engine takes four floating-point inputs and composes a 4D vector.

       The input fields can have multiple values, allowing the engine to compose several  vectors
       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

     SoMFFloat           x
          The x component.

     SoMFFloat           y
          The y component.

     SoMFFloat           z
          The z component.

     SoMFFloat           w
          The w component.

OUTPUTS

     (SoMFVec4f)         vector
          Vector composed of x, y, z, and w.

METHODS

                         SoComposeVec4f()
