3D Virtual Reality Browsers Review

Several VR browsers are available and do a fine job of implementing that virtual reality specification. As this article is being written, it means photo-realism in motion. The photo-reality spec was approved in mid-1996 and the best browsers support it.

Not all VR-browsers are equal, however. This section looks at some of them, comparing them specifically in terms of how well they handle photo realistic motion files exported from 3D application with the virtual reality Exporter. Because you need to place the objects at the same coordinates, you cannot see them all simultaneously.

The best way to handle them is to hide and unhide them as necessary. The initial camera view’s setting for the world gives you a view of the L.O.D objects. Navigate forward in the view port toward the building immediately in front of you. As you draw near, the plain texture-mapped-box building changes to a fully modeled version.

The Anchor helper creates a link from an object in the photo-realism world to another URL (.WRL or.HTML file) or to another camera viewpoint in the same world. The touch sensor helper starts an animation or sound file when the user clicks the linked object. Things change very quickly on the Web and what is true today may not be true-or be only relatively true-tomorrow.

Other browsers may appear that are superior to the ones discussed here, but these browsers are the best available today, however. They are likely to continue to evolve along with the virtua-realism specification itself. On the other hand, some browsers have not evolved fast enough to be included in this review.

This photo-realistic browser adds some extra functionality (called VRBL) that is not in the virtual reality 1.0 specification, but these extra functions (which are for basic animation) have been superseded by the new functionality in virtual-realism.

However, that kind of browser has been discontinued in favor of more recent products by other vendors. Changing virtual reality browsers is a simple task: download the new browser and run the setup program. In most cases, this automatically installs the new browser over the old one. The next time you access a virtual reality world, the new browser should run.
