SYNOPSIS:
    nurb: a structure storing a NURB (Non-Uniform Rational B-Spline)
            forming a flexible smooth line/patch/object that can be
            used to approximate lines, surfaces or volumes.

DESCRIPTION:
    Eccet can embed NURB objects in its rendered output.

    NURBs have lots of rendering options like showing as wireframe,
    flat or shaded. See NURB_VISFLAGS for details on this.

    NURBs live in the global coordinate system and can be moved,
    turned, scaled and bent as the user wishes. They can be copied
    into the volume, e.g. to serve as a template.
