It took approximately three days to understand the tools well enough to work with them. It can take one to two months to become proficient. Although a good authoring tool will eliminate the need to know the details of the VRML 2.0 specification, proficient VRML 2.0 authors are familiar with the Nodes and Fields so they can take full advantage of the capabilities of VRML 2.0. VRML 1.0 allowed content developers to create static 3D worlds which contained links to web content. Sensors - Interaction with the User.
Sensors provide mechanisms for the user to interact with objects in the world.
Functionally, they generate events based on time or user action. Virtual Reality can enhance communications in many professional areas. From the perspective of an engineer or designer, the more common way of discussing designs is to print out a 2-D drawing of the part or assembly, mark it up, and forward it to the other parties, often by mail, it is very time consuming and subject to errors in interpretation. The VRML authoring tools discussed have ever-richer feature sets and can now do things that were, until very recently, the domain of expensive specialized modeling software. The drawback is that they are just out of Beta stage, and could use a little more time for the level of robustness needed for commercial use.
