BRL-CAD is a powerful constructive solid geometry solid modeling system that includes an interactive geometry editor, ray-tracing support for rendering and geometric analysis, path-tracing for realistic image synthesis, network distributed framebuffer support, and image and signal-processing tools.
ClarkConnect is a powerful yet easy-to-use server/gateway software solution designed for the small/medium-sized organization. The software provides all the necessary server tools to run an organization: email, antivirus, antispam, file sharing, groupware, VPN, firewall, intrusion detection/prevention, content filtering, bandwidth management, multi-WAN and more.
The debug memory allocation or dmalloc library is a drop-in replacement for the system's native memory management routines. It provides powerful debugging facilities which are configurable at runtime. These facilities include such things as memory-leak tracking, fence-post write detection, file/line number reporting, and general logging of statistics. The library has been run successfully on a wide variety of operating systems. It also provides support for the debugging of threaded programs.
GLE is a library package of C functions that draw extruded surfaces, including surfaces of revolution, sweeps, tubes, polycones, polycylinders and helicoids. Generically, the extruded surface is specified with a 2D polyline that is extruded along a 3D path. A local coordinate system allows for additional flexibility in the primitives drawn. Extrusions may be texture mapped in a variety of ways. The GLE library generates 3D triangle coordinates, lighting normal vectors and texture coordinates as output. GLE uses the GL or OpenGL API's to perform the actual rendering.
