CUBE VIEWER USER'S GUIDE

Before using the Cube Viewer set the size of your browser window. The default size will work, but a larger window size is also supported. Once you have gone to an html sight that uses the Cube Viewer you are prompted to set the size of the viewer and then the relative size of the three views. The size of the viewer is set by manipulating the green box and the relative size of the three views is set by moving the red ball in the middle of the display. At anytime after loading you can reset these parameters, but it will result in a long delay while the images are recreated.

Once the size is set, the data is loaded in and the frames are created. At this point the Cube Viewer has two main operating modes:

• run mode which allows you to play a movie backwards or forwards along any of three principle directions with a single key command
• frame mode which allows actions such as advancing by a single frame.

The run mode has several button options:

• front- movie through the i3 direction of the cube
• side- movie through the i2 direction of the cube
• top- movie through the i1 direction of the cube
• 1- to run the selected movie forward
• 0- to run the selected movie backwards
• +- increase the delay between frames by 50 ms
• -- decrease the delay between frames by 50 ms
• stop-to stop the current movie
• h- to pause the movie

The frame mode can be selected at any time by either clicking on one of the views with the mouse or using the appropriate key command:

• Front- set the front as the active frame
• Side- set the side as the active frame
• Top- set the top as the active frame
• m - to go backward one frame along active frame direction
• n - to go forward one frame along active frame direction

The Cube Viewer also recognizes:

• quit - to quit the applet
• a - to repaint the applet, necessary when you resize the window, or have temporarily covered the display.
