Color Bar Information and Main Window. Time Frame Control Widgets:

Main Draw Area:

The Main Draw Area is the main rendering window for G3D. In the upper left corner is drawn a small view of data and axes to remind the user of the current orientation of the data set. The x, y and z axes are colored red, green, and blue respectively. In the main draw area, objects such as grids, isosurfaces, rock layers, and so on,  will be rendered. The user will also use the mouse in this area to manipulate objects as we described, for example, in the previous paragraph concerning view control (`clicking and dragging' the mouse in the drawing area provides joy-stick control of the orientation).
