/**
* This scene contains a single NurbsTrimmedSurface rendering one-quarter of a cylindrical segment; with a triangular notch cut from one edge. The "solid" field of the surface is set false so 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.

This program uses the
X3D Java Scene Access Interface Library (X3DJSAIL).
It has been produced using the
X3dToJava.xslt
stylesheet
(version control)
which is used to create Java source code from an original .x3d model.
