In the days of VRML 1.0, NURBS seemed to be too complex to be adapted to the specification. Current development of hardware compels us to reevaluate this idea: While CPU clocks break the 1-GHz barrier, users still have to cope with 56K modems. NURBS meet exactly these demands. A NURBS description is a compact storage form, but its evaluation requires more computational effort. In addition, NURBS can be utilized for morphing effects and they provide a means for a smooth LOD. Adopting trimmed

We take a closer look at LOD, animations and trimmed NURBS. Finally, we look ahead and briefly touch on an emerging new representation, subdivision surfaces.
