This fully featured program boasts the best control over lighting, easiest access to textures and fully editable shapes. It can create VRML models for publishing models on the web and has other bells and whistles such as stereoscopic output. Instead of drawing tools, VR, uses pre-defined shapes that are dragged onto the plan or elevation. Extensive libraries help this system quite a bit. This makes for very fast models, but less fine control.
Lighting is also limited to a preset look.
This is one of the most effortless VRML authoring programs. This is particularly valuable to Mac owners as the first and still one of the few VRML apps for Mac. If you have a VRML plug-in for your browser check out some VRML stage designs here. Virtus products are available for Mac and Windows. Files can be transferred between applications and between platforms.
