Introduction

The example in this section shows you how to create a simple virtual world using the 3D

World Editor. The example does not show everything that you can do with the editor, but

it does show you how to perform some basic tasks to get started.

This example assumes that you have set your default editor to be the 3D World Editor.

For details, see “Set the Default Viewer” on page 2-2.

This example describes the steps to build a slightly simplified version of the virtual world

that you see if you enter the following command in the MATLAB command window:

edit(vrworld('vrdeform.wrl'))

Define the Problem

Suppose you want to simulate and visualize in virtual reality the deformation of a

sphere. In your virtual world, you want to have two boxes representing rigid plates (B1,

B2) and an elastic sphere (S) between them. All three of the objects are center-aligned

along the x-axis. The boxes B1 and B2 move toward S with identical velocities, but

they move in opposite directions. As they reach the sphere S, they start to deform it by

reducing its x dimension and stretching both its y and z dimensions.

Here is how this virtual world looks:
