The "solid" field of the surface is set false for so that surface is visible from both sides. 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'/>
