/**
* The {@code Shape3D} base class provides definitions of common properties for
* objects that represent some form of 3D geometric shape. These properties
* include:
*
* - The {@link Material} to be applied to the fillable interior of the
* shape or the outline of the shape (see {@link #setMaterial}).
*
- The draw model properties that defines how to render its geometry (see {@link #setDrawMode}).
*
- The face culling properties that defines which face to cull (see {@link #setCullFace}).
*
*
* Note that this is a conditional feature. See
* {@link javafx.application.ConditionalFeature#SCENE3D ConditionalFeature.SCENE3D}
* for more information.
*
*
* An application should not extend the Shape3D class directly. Doing so may lead to
* an UnsupportedOperationException being thrown.
