Because few paradigms for 3-D interface design exist buy renagel 800 mg, ¯exibility to quickly try di¨erent combinations of hardware devices and software design layout features has also been a design requirement. Core functionality is provided by Facet, which concurrently manages 3-D manipulatable components (blocks) that enable di¨erent modalities of resource display or user interaction. In this way, blocks can be combined by faculty to build men- tored lessons or by students in real-time within the VE. Blocks can also be constructed by a system architect to extend the core features of Facet and build new user-interface tools. Facet can manage newly created 3-D user-interface widgets inserted within any block. These 3-D widgets are similar to selectable lists, scrollbars, and buttons common to any Windows-based user interface, 8. For example, combination of 3-D widgets, such as text, images, and buttons, currently comprise the Study Guide Block, while the Video Block includes 3-D start, stop, and loop button widgets. The sequence of pages or tabbed sections can be set, as can instructions as to which models to load or remove, where to place them, and whether or not to group them. Page headers and their text and link buttons with anchors for accessing any resources can be entered. The Lesson Editor generates an ASCII ®le that can also be further modi®ed using any text editor. An expanding list of Xresources can be used to specify changes to user interface characteristics such as color, size, position, device baud rate, and communications port without the need to recompile the application. Facet can also be extended to support any type of input/output (I/O) devices and their associated device drivers via shared objects loaded at run time. This simple ASCII ®le speci®es user-interface commands as event de®nitions associated with command-to-action mappings.
