CUBE VIEWER

As more and more of SEP's research moves into the 3-D , 2-D viewers are no longer sufficient. Often the researcher can gain new insight by looking at orthogonal planes of the data simultaneously, and having the ability to run through the 3-D cube along any of the three planes. As a result SEP has developed the in-house 3-D viewers, X11movie and Cubeplot, that provide this extra level of sophistication. These programs have proven immensely useful, but they:

• can not be run on the web without putting considerable strain on the host machine.
• suffer from
  • a lack of interactivity in the case of Cubeplot
  • difficult menu controls in the case of X11movie

The Cube Viewer solves these problems. The Cube Viewer works along the same principle as the Animator. It loads in a SEPJava file one frame of the cube at a time, creating the front image during loading. Once the entire cube has been loaded, the side and top images are created. The display (Figure 4) of the Cube Viewer follows closely Cubeplot. The main screen is broken into three portions:

• Bottom left, the front view, constant i3 (slowest direction of the array).
• Bottom right, the side view, constant i2.
• Top left, the front view, constant i1 (fastest direction of the array).

On each displayed frame two yellow lines show the relative location of the other two displayed planes. The user can then use a series of key and mouse controls to navigate through the cube. Appendix D provides a user's guide to the Cube Viewer.
