TEMPRA Modeler(tm) Introduced at Comdex
3D Modeling and Rendering Software Rounds Out
TEMPRA Multimedia Product Line

(COMDEX/FALL '93, Las Vegas -- Nov. 15, 1993)  TEMPRA, a division of
 Mathematica, Inc., the Lakeland, Florida-based multimedia software
 company, announces the addition of TEMPRA Modeler, a Windows-based
 modeling and rendering program for creating photorealistic 3D images,
 to its TEMPRA family.  The Gamma release can be ordered for $99,
 November 15, 1993.  Company representatives will demonstrate TEMPRA
 Modeler at Comdex booth A284 in the Las Vegas Convention Center.
 Unlike CAD systems, TEMPRA Modeler is based on solid modeling
 (non-polygonal) technology, a building block approach in which basic
 solids like spheres, cylinders, cones, and other shapes are combined
 to form complex solids. TEMPRA Modeler offers artists the option of
 rendering images with ray tracing or polygonal shading. Artists can
 use polygonal shading to quickly preview the image as it is being
 created, then use ray trace to generate the final image. Ray trace is
 used to achieve 24-bit true-color images, which feature shadows,
 reflections, surface mapping, and transparency. Because TEMPRA Modeler
 uses a mathematical formula to create models, rendered images are
 smoother than polygonal equivalent images, such as those created in
 expensive programs like Autodesk 3D Studio, Crystal Graphics' Crystal
 Topas, and Macromedia MacroModel.
 "We are excited to be introducing TEMPRA Modeler at this Comdex show,
 especially with the introduction of our other new Windows products,"
 said Derek Hodges, president of Mathematica, Inc. "Our customers now
 have all the multimedia tools they could dream of. Not only do we
 believe TEMPRA products to be technically the best available, but they
 are priced for the mass multimedia market."
 TEMPRA Modeler's 3D modeling capabilities include spline-curve control,
 boolean functions, TrueType font support, perspective and orthographic
 model views, spot/parallel/point light sources, batch rendering, and
 alpha channel composition. Models are saved and imported in MOD file
 format and can be exported into DXF file format. Rendered images can
 be saved in standard file formats, including TGA, PCX, GIF, TIFF, WIN,
 and BMP.
 Advanced users can upgrade to TEMPRA Modeler Professional. While TEMPRA
 Modeler is a 16-bit Windows application, the professional version is
 32-bit capable, giving users increased speed. The program includes
 key-frame and timeline based animation support, for 8-bit FLI and FLC
 and 16- and 24-bit FLX animations.  Additionally, TEMPRA Modeler
 Professional features single frame animation controller (VCR) support.
 TEMPRA Modeler Professional will retail for $995 and begins shipping
 in February 1994.
 TEMPRA is a division of Mathematica, Inc., which is filing to have its
 company name changed to TEMPRA, Inc. Upon completion of this transfer,
 Wolfram Research at 100 Trade Center Drive, Champaign, Illinois
 (217) 398-0700, is the sole owner of all rights in and to the trademark
