Internal Document Only -- Watch Us Work

When you specify the correct html page, the page loads displaying two or more VRML worlds, each within a Cosmo Player window. There is also Java applet on the bottom of the display. The applet controls all aspects of the VRML worlds. When you press on a button in the Java applet, all the worlds are changed accordingly.

Most of the transformations have a row of buttons. From left to right, these produce a large negative motion, successively smaller negative motions, a small positive motion, and successively larger positive motions. Red buttons cause the biggest changes and yellow buttons the smallest.

To start using the Multi-View Applet, we recommend you first click on the Center Ball button, then experiment with the Object Rotation buttons.

Applet Control Panel

Pan

Panning moves the camera up, down, left, or right. The effect is to shift the entire scene in each of the Cosmo Player windows. Panning is controlled by 4 buttons arranged in a diamond. The amount of motion caused by clicking one of the buttons is based both on the size of the VRML models and a variable contained in the program.

 

Reset World

This button completely resets the worlds to the initial state.

 

Center Ball

This button centers the ball to the midpoint of the object. This is used for optimal rotations.

 

Scale

This button scales only the object, in the amount according to the button you press.

 

Zoom

This button zooms either in or out depending on which button you press. Every component in the world will get zoomed, not only the object.

 

Object Translation

These series of three subsets of multiple buttons move the object in the corresponding axis.

 

Reset Object

This resets only the object to its original position and scale.

 

Object Rotation

These series of three subsets of multiple buttons rotate the object based on the ball position (rotates around the ball).

 

Ball Translation

These series of three subsets of multiple buttons move the ball in the corresponding axis. The ball is used as a center for the rotation of the object.

 

Reset Ball

This resets only the ball to its original position and scale.

 

Output box

This text box outputs what you pressed, if measurable, and tells you the amount and the current value for that particular transform, if applicable.

 

Clear Box

Deletes the contents of the text box.
