PROGRAM TITLE HyperGeo SHORT DESCRIPTION HyperGeo is a tool for investigating geometrical properties of four-dimensional objects constructed in hyperspace. It will display three-dimensional images, it creates from a 4-D object, by projecting onto or intersecting with a 3-D hyper-plane. You, as the user, have full control over the objects orientation and position. The 3-D images can be presented in a number of different display modes including, linear projection, stereoscopic projection (for use with colored "3D" glasses), hidden-line, surface relief, and solid surface rendering. Included are data files listing a number of 4-D objects definitions including, the hypercube and other regular and irregular hyperobjects. The data files are simple text files which the user can create and edit as desired to construct many new objects for investigating with HyperGeo.

First, it is ideally suited for use in a classroom at the high-school or college level as a visual tool used in the study of analytical geometry or solid descriptive geometry. And second, the program should be fascinating to anyone who possesses even a laymen's interest in mathematics. HyperGeo is naturally perfect in the mathematics or scientific software categories, but it will also be enjoyed as entertainment or graphics software since it includes a variety of options and object forming capabilities. WareCraft is now making an offer to anyone who purchases the shareware version of HyperGeo and sends them a self addressed stamped envelope they will receive a free pair of "3D" glasses that are required to view the stereoscopic projection display mode.
