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 Passenger Prescreening System II The program was then replaced by a similar program called Secure Flight in early 2005 generating the same concerns over privacy and civil liberties. However, due to public concerns, Secure Flight is not due to become fully operational until 2010. CAPPS II grounded innocent Americans due to false positives. One notable example is the grounding of Senator Ted Kennedy in 2004. Computer Assisted Passenger Prescreening System II The Computer Assisted Passenger Prescreening System II (CAPPS II) was a program of the United States Department of Homeland Security (DHS) instituted to increase security at airports by assessing the risk level of
