Virtual Reality Toolbox

Adding a Virtual Reality Toolbox Block

This procedure uses the Simulink model vrtut3.mdl as an example to explain how to add a Virtual Reality Toolbox block to your model. The model generates the values for the position of B1, the position of B2, and the dimensions of S for the problem previously defined. See Defining the Problem.

1. From the directory C:\<matlab root>\toolbox\vr\vrdemos\, copy the file vrtut3.mdl to your MATLAB working directory.
2. Start MATLAB, and then change the current directory to your MATLAB working directory.
3. In the MATLAB Command Window, type

• vrtut3 
  

1. A Simulink window opens with a model that does not contain a Virtual Reality Toolbox block. Instead, this model uses Scope blocks to temporarily monitor the relevant signals.

   

4. From the MATLAB Command Window, type

• vrlib
  

1. The Virtual Reality Toolbox library opens.
   
   

5. From the Library window, drag-and-drop the VR Sink block to the Simulink diagram. You can then close the Library: vrlib window.

Your next task is to create a virtual world that you will associate with the VR Sink block. See Creating a Sphere in a Virtual World.
