Building 3D Models for the Web Creating Multiple Viewpoints

Using the Anchor node, you can add navigation cues to your VRML world, similar to the red triangles in the SGI Out of Box Experience.

An Example

1. Log into one of the SGIs, cheetah.ma.iup.edu, jaguar.ma.iup.edu, or leopard.ma.iup.edu.
2. Change to your public_html directory:
   

   leopard 1% cd public_html
   

3. Copy the example from the ls499 directory and give public read access to it.
   

   leopard 2% cp /usr/people/ls499/navigate.wrl .
   leopard 3% chmod 644 navigate.wrl

4. Edit the example, replacing the asterisks with appropriate numbers.
   

   leopard 1% pico viewpoints.wrl
   

   Choose positions and orientations so that the viewpoints are from the front, side, and top.
5. View the changes in your Web browser by going to the URL http://cheetah.ma.iup.edu/~username/viewpoints.wrl, where username is replaced by your own username.
6. Navigate to the various viewpoints by clicking on the "View" arrows at the bottom of the browser window or by holding down the mouse button in the browser window until a menu pops up.
7. If you finish this exercise early, try modifying navigate.wrl so that when you click on the sphere you go to the house that you built in VRML Assignment 2.
