Application Layout

The Volrend interface (see Figure ) consists of an image region with a control panel on the right hand side. The window is fully resizable, and the image region will scale to fill the area available. The control panel consists of the alpha control widget; buttons to open files, dump TIFF files, render the object and specify image interpolation; and sliders to adjust the zoom factor and brightness.
