DESCRIPTION

       This node creates texture coordinates for points on an object's surface by projecting them
       onto  a  plane. The directionS and directionT fields define the plane. The S coordinate is
       computed as the distance from the object-space origin along the vector  specified  in  the
       directionS field. The T coordinate is computed similarly, using the directionT field.

       The  length  of  the  direction  vector  is  also  taken into account. For example, assume
       directionS is (0.5, 0, 0) and directionT is (0, 1, 0). The square defined by the (x, y, z)
       vertices:

          (-1, -1, 0) (1, -1, 0) (1, 1, 0) (-1, 1, 0)

     will be assigned the (s, t) texture coordinates:

          (-2, -1) (2, -1) (2, 1) (-2, 1)

FIELDS

     SoSFVec3f           directionS
     SoSFVec3f           directionT
          Directions of projection for S and T coordinates.

METHODS

                         SoTextureCoordinatePlane()
          Creates a texture function node with default settings.

     static SoType       getClassTypeId()
          Returns type identifier for this class.

ACTION BEHAVIOR

       SoGLRenderAction, SoCallbackAction, SoRayPickAction
          Sets the current texture function in the state.
