And Truevision Inc’s new single-board 80860-based Horizon860 will support Pixar Inc’s PhotoRealistic RenderMan rendering software, the companies announced. Truevision will market PhotoRealistic RenderMan for the Horizon860 in three versions, beginning with OS/2 in the fourth quarter of 1990 and following with MS-DOS and Unix versions. It will also support the Truevision TGA file format, which is supported by more than 300 personal computer applications. Pixar’s RenderMan Interface specifies a comprehensive way for a software program to describe objects, scenes, lights and cameras so that a desktop computer can create photorealistic pictures. The Truevision RenderPak, with Photo realistic RenderMan and the 8Mb configuration of the Horizon860, will be available for $8,000, and the software alone will be $1,500. The Horizon860 is the first member of a new HorizonLine family and is designed to accelerate three-dimensional animati on, computer-aided design and other graphics applications curr ently running on Truevision’s Targa and ATVista personal comput ers. The board is claimed to draw 40,000 polygons a second, eight times faster than such systems as the Silican Graphics Inc Personal Iris. Its expandable HorizonBus is claimed to transfer data at 264M-bytes per second, 100 times the transfer rate of an AT. Memory modules can be added to give up to 64Mb in one slot.
