  6.  
  7.  
  8.  SurfaceType SRAISE( SurfaceType Srf, ConstantType Direction,
  9.                                                       NumericType NewOrder )
  10.  
  11. Raises Srf to the specified NewOrder in the specified
  12. Direction.
  13.  
  14. Example:
  15.  
  16.     Srf = ruledSrf( cbezier( list( ctlpt( E3, -0.5, -0.5, 0.0 ),
  17.                                    ctlpt( E3,  0.5, -0.5, 0.0 ) ) ),
  18.                     cbezier( list( ctlpt( E3, -0.5,  0.5, 0.0 ),
  19.                                    ctlpt( E3,  0.5,  0.5, 0.0 ) ) ) );
  20.     Srf = SRAISE( SRAISE( Srf, ROW, 3 ), COL, 3 );
  21.  
  22. constructs a bilinear flat ruled surface and raises both its directions to be
  23. a bi-quadratic surface.
