I'm not too interested in panoramas, but the VR's that can be made from them. I'm getting more clients who are interested in both environmental and object vr's. At this point I'm using Apple's QT VR Authoring Studio - which only runs under OS 9 & PowerPC chips - and hasn't been upgraded since release in 1997. That said it is the only reason I keep a g5, just to run it. Also VR Worx - which has never run well on the PC but does fine on the g5. The Trouble with both of these is they do not do spherical VR's - they do cylindrical and object VR's quite well and with the inexpensive Cubic Connector/Converter combo interactive maps, sounds, hot spots to nodes, url's etc are very doable. I've several like this [multinodes] on my website i did for State of IL. and Kane Co. - http://www.digitalmediart.com/vr.html -but I've several clients that just 'gotta have' sphericals. So the search continues: Panotools does it but has problems for me with how the software is activated; So looking like RealViz - which is somewhat cheaper. There must be more out there. Another great reference site: http://vrm.vrway.com/index.html with articles etc. but terrible layout.
