VRML? You know HTML is the current language of the Internet. It’s what tells web browser such as Netscape and Explorer how to show the files that are on web sites. VRML shows 3 dimensional pictures. VRML (Virtual Reality Modeling Language ) is the HTML equivalent for computer careers creating and showing scenes on the Internet in three dimensions.Yes, the Internet in 3D. And you don’t even need to wear funny glasses! People do need special browsers to see your VRML 3D pictures, but these are also available as plug ins to Netscape and Explorer. This is the future, folks. Do you think people will be satisfied to read words on a 2 dimensional page when they can explore entire worlds through VRML? Actually, yes they will, assuming the words are interesting. VRML is not going to destroy books and reading any more than movies and TV did. However, in the future, we will want to spend time exploring worldsWhen you "chat" with friends and strangers in the future, you’ll do it in 3D environments. You’ll all have an "avatar," which is a 3-dimensional representation of yourself. Maybe your avatar will look like you do, maybe it will be somewhat . . . improved. Up to you. Your avatar can meet and talk with other avatars in any congenial location. Maybe a bar, maybe a park, maybe a . . . well, I won’t go there. We all know what most people use the Internet for already. Next thing you know, people will be writing Dear Abby and getting divorces because they’ve fallen in love with someone else’s avatar. Officially, VRML is a platform-independent file format for sharing 3D worlds on the WebThat’s what we’ve been talking about, and the possibilities are limitless. Imagine journeying with Frodo through The Lord of the Rings. Or following Sherlock Holmes through the fogs of 1890 London. Virtual Reality Modeling Language worlds can be interactive and animated, and can include embedded hyperlinks to other Web documents. The funny thing is, as a computer career writing Virtual Reality Modeling Language is not hard at allYou use ASCII. That’s right, you can design a 3 D world of wondrous beauty and detail with Notepad. There are some details, of course. Then you describe your setting with "nodes." Which are basically focus points, shapes, etc. A node is an individual object or operation in the 3D model. For example, a node can be a light, an object like a cube, or an operation like a rotation. You use a 3D axis model to define what goes where. You write a hierarchal description of the model as well as the scene which contains it. This is referred to as a scene graph. Remember graphs in high school math, don’t you? You have an x axis and a y axis, and any point can be defined as where it is in relation to the x axis and the y axis. To map out VRML, you add a z axis. So part of your description will be describing shapes with the 3 axis. You can also change/add lighting, color, shining, the texture of your images etc. VRML - Page 2 |
