BRL-CAD BRL-CAD BRL-CAD is a constructive solid geometry (CSG) solid modeling computer-aided design (CAD) system. It includes an interactive geometry editor, ray tracing support for graphics rendering and geometric analysis, computer network distributed framebuffer support, scripting, image-processing and signal-processing tools. The entire package is distributed in source code and binary form. Although BRL-CAD can be used for a variety of engineering and graphics applications, the package's primary purpose continues to be the support of ballistic and electromagnetic analyses. In keeping with the Unix philosophy of developing independent tools to perform single, specific tasks and then linking the tools together in a
Computer-assisted reporting other disciplines by journalists. One researcher argues the "age of computer-assisted reporting" began in 1952, when CBS television used a UNIVAC I computer to analyze returns from the U.S. presidential election. One of the earliest examples came in 1967, after riots in Detroit, when Philip Meyer of the Detroit Free Press used a mainframe computer to show that people who had attended college were equally likely to have rioted as were high school dropouts. Since the 1950s, computer-assisted developed to the point that databases became central to the journalist's work by the 1980s. In his book, Precision Journalism, the first
