    <meta content='This scene contains a single NurbsPatchSurface rendering one-quarter of a cylindrical segment. The "solid" field of the surface is set true for single-sided rendering, and Nurbs coordinates are oriented so that the outer surface of the cylinder is visible. Surface has semi-transparent material appearance. Scene also contains unit-length line segments defining x-y-z coordinate axes. Defined Viewpoints show the inner and outer sides of the cylindrical surface' name='description'/>
