3D Graphics Technology: VRML Part I - Introduction


Virtual reality modeling language provides the graphics capability to let you create 3D objects, even whole worlds, which you can upload to your website. Visitors can then interact with these virtual items. VRML has many applications. In this first article in a series, Eliana Stavrou explains the basics and provide examples.

3D Graphics Technology: VRML Part I - Introduction - Examples
(Page 4 of 4 )

In this section Iím providing some examples to demonstrate the importance of 3D applications which are developed with VRML.

As you can see, you can develop anything from simple to very complex objects.

The following screenshot presents a 3D chair model from IKEA. Designers can use VRML to construct ideas that they can show to potential customers to explore.

In addition, they can develop more complex environments, presenting a complete product range to customers. For example, a comprehensive interior design service, the Outline3D, can be accessed at www.Outline3D.com.

The basic functionality is free of charge and includes the following options:

  • Easily draw any kind of 2D interior and generate a 3D model from it. 
  • Add furniture, finishings and fittings from a comprehensive catalog. 
  • Get detailed specification for created interior. 

The following screenshot shows the result when using the service to arrange specific furniture in a room space:

VRML can be used effectively in other areas, such as distance learning. The following screenshot is from a demo developed by ParallelGraphics. Chemistry students can use this demo to view atomic structure like never before! One click on the chemical element of your choice in the Periodic Table displays a detailed 3D model of an atom with all the protons, neutrons and electrons speeding through their orbits.

By doing a simple search on the Internet, you will find thousands of VRML examples, many of which are fascinating and unconventional.

Conclusions

My objective when writing the first part of this article was to introduce you to VRML language. By now we know that VRML is a flexible platform for creating interactive 3D worlds. We know its main features, and that we need special VRML plug-in applications to view VRML files. The screenshots provided show us some of the many capabilities of the language and some of the areas (i.e. business, education, fun) we can use VRML to get the benefit of what it has to offer.

In the next article I will discuss the syntax of VRML and include appropriate examples that will show how we can use some of VRMLís main programmatical features.
