Guitta: thanks again. It's looking like I will be leaning toward Quicktime VR. I spent part of today researching the Web for VRML sites. Found thousands, but most that I opened were dated 1996/7/8 and the State-of-the-Art doesn't seem to have advanced much since I played with it back them.

Lynn: Even ParallelGraphics seems pretty crude. There's just no resolution. I've been approached on a project to re-create historic battlefields. My contact person wants to be able to fly through the battleground terrain and look at whatever pleases him. I see the appeal of this, but comparing a Vue rendered scene with a VRML scene, I'm leaning toward a Vue landscape of the terrain, then a series of QVR movies on a time line that show what the oppposing commanders [or lead units] could see at various crucial points as the battle unfolded. In any event, this would off a CD and not from the Web. Thanks for your help.
