Create a Virtual World

Create a Virtual World
There are a number of tasks involved in creating a virtual world. You can use the 3D
World Editor throughout the process of building a virtual world, and you can perform
activities in many different ways.
For a step-by-step tutorial about building a virtual world using the 3D World Editor, see
“Build and Connect a Virtual World”.
In general, the following is a common workflow for creating a virtual world using the 3D
World Editor. This example workflow includes optional tasks and a small subset of the
types of tasks that you can perform. For more information, see “Basic Editing” on page
6-11.
1
Open a new VRML file.
2
Under the ROOT node, optionally add:
• A WorldInfo node to document the virtual world.
• A NavigationInfo node to define overall navigation characteristics of the
virtual world, such as the Avatar size.
3
Under the ROOT node, add a Transform node in the virtual world for each object
that you want to share properties with other object in that same Transform node.
4
Under the Transform node, include nodes in a hierarchy, such as:
children
Shape
appearance
Appearance
material
Material
texture
textureTransform
Geometry
Box
5
Use the object properties edit pane to change default property values to create the
effects that you want.
6
Insert 3D World Editor library objects to define aspects, such as textures, for virtual
world objects.
• Give a VRML DEF name to each object that you create, so that you can access
them using Simulink 3D Animation.
