For stage visualisation, ESP Vision is hard to beat.
There is a VW plug-in and as with Artlantis, changes made in VW can be updated in the ESP/Artlantis files without having to make any other changes, lighting and rendering settings etc stay the same.
Artlantis is a stand alone programme, but requires 3D files to input prior to rendering and animating etc.

ESP Vision is also a stand alone programme that also allows programming of lighting desks, lighting plots, and anything else happening in a stage environment.

Also of note the Opening and Closing Ceremony at the Beijing 2008 Olympics was modeled in VectorWorks and visualised in ESP Vision
