Version 2.0 includes routines for anti-aliasing, object and animation "pathing," geometry
construction, true-perspective texture correction, vertex-based lighting, and support for new
input/output devices. Price: $2,400 for DOS.

WorldToolKit for Windows. Lets users create VR applications and view real-time,
multidimensional data. Users can give data various attributes, such as position, size,
orientation, color, shape, and behavior. Abstract information from a simple spreadsheet can
be presented in a 3D virtual environment, where elements move or change colors to reflect
changes in the data. Users then can navigate around the environment to see views of the data
not apparent on spreadsheets. WorldToolKit for Windows requires a 386 or higher PC running
Windows 3.t; a 256 or better color display, and a Windows C compiler. Price: $795,
