Status Items

The Status Bar displays the current status of the Viewer. Here is a detailed description of each item:

1. Scale. This item displays the current scale setting. The scale can be shown in four different scale units. If the Viewer is in Overview Mode, the scale applies to the Selection Box. If the Viewer is in Zoomed Mode, the scale applies to the full screen image. Clicking-on the Scale display will cause it to reset to its initial value.

2. Zoom. This item displays the magnification factor for the display. The value is the number of times the display has been magnified. For example, if the zoom factor is two, the image size will be blown up to twice its unzoomed size. If the Viewer is in Overview Mode, the zoom applies to the Selection Box. If the Viewer is in Zoomed Mode, the zoom applies to the full screen image. Clicking-on the Zoom display will cause it to reset to its initial value.

3. Pan X, Y, Z. This item displays the current pan settings for the Viewer. This is the amount of movement in the east/west (X), north/south (Y), and vertical (Z) directions. A value of one corresponds to the width, height or depth of the cave. For example, if the X value is 0.5, the image would be panned half the cave width to the east. If the Viewer is in Overview Mode, the pan applies to the Selection Box. If the Viewer is in Zoomed Mode, the pan applies to the full screen image. Clicking-on the Pan display will cause it to reset to its initial value.

4. Angle. This item displays the current yaw rotation of the cave in degrees. The angle can be displayed in several different angle modes that base the angle on different references. If the Viewer is in Overview Mode, the angle applies to the Selection Box. If the Viewer is in Zoomed Mode, the angle applies to the full screen image. Clicking-on the Angle display will cause it to reset to zero.

5. Pitch. This item displays the current pitch rotation of the cave in degrees. The pitch rotation only manifests itself when the Viewer is in Zoomed Mode. Clicking-on the Pitch display will cause it to reset to zero.

6. Mode. This item displays the current view mode and angle mode in two boxes. The first box indicates if the program is in Plan or Profile mode. The second item indicates if the program is in Overview or Zoomed mode. Clicking-on either of the boxes causes the mode to toggle. To conserve space, the items are abbreviated:

7. FPS. This item displays the number of frames per second the image is being drawn at. The rate is a function of the computer speed, the size of the cave and what features are being displayed. The higher the number, the faster cave is being displayed. Frame rates faster than about 2 FPS allow for real-time cave animations.
