  # [appinfo] Produce wireframe or transparent beam hemisphere. Typical uses include sonar/radar/light beams. Negative range values invert base and apex at same relative location. Default: hemisphere with centroid at (0 0 0) and radius 1 atop x-z plane.

  initializeOnly SFString	 name    # [appinfo] Assigning a name to a BeamHemisphere aids tracing
