DESCRIPTION

       This engine takes two floating-point inputs and composes a 2D floating-point vector.

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

INPUTS

     SoMFFloat           x
          The x component.

     SoMFFloat           y
          The y component.

OUTPUTS

     (SoMFVec2f)         vector
          Vector composed of x and y components.

METHODS

                         SoComposeVec2f()
          Constructor

FILE FORMAT/DEFAULTS

       ComposeVec2f {
          x  0
          y  0
