#BRL CAD COMMANDS CODE#
The following code illustrates how individual commands are defined within the library. So far this is a small subset of the brl-cad primitives with some notion of object-oriented design, being emitted as tcl scripts that mged can directly process into database (.g) files. The Geometry Editing Library (libged) defines commands for working with BRL-CAD models. This means BRL-CAD can "study physical phenomena such as ballistic penetration and thermal, radiative, neutron, and other types of transport" It does also support boundary representation. These documents are available for download at <. In contrast to many other 3D modelling applications, BRL-CAD primarily uses CSG rather than boundary representation. comprehensive list of the user commands available (Butler et al., 2001). In keeping with the Unix philosophy of developing independent tools to perform single, specific tasks and then linking the tools together in a package, BRL-CAD is basically a collection of libraries, tools, and utilities that work together to create, raytrace, and interrogate geometry and manipulate files and data.
#BRL CAD COMMANDS MAC OS#
net /projects /brlcad /files /?source=navbarĬross-platform (BSD, Linux, Mac OS X, Solaris, and Windows, among others)Īlthough 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. The application side of BRL-CAD also offers a number of tools and utilities that are primarily concerned with geometric conversion, interrogation, image format conversion, and command-line-oriented image manipulation. Each library is designed for a specific purpose: creating, editing, and raytracing geometry, and image handling.
#BRL CAD COMMANDS SOFTWARE#
The BRL-CAD libraries are designed primarily for the geometric modeler who also wants to tinker with software and design custom tools. In contrast to many other 3D modelling applications, BRL-CAD primarily uses CSG rather than boundary representation.
The entire package is distributed in source code and binary form.Īlthough 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. mged> in ground.s rpp -15 15 -15 15 -1 1 mged> r ground.r u ground.s mged> attr set ground.r simulate::type region. BRL-CAD's simulated gravity acts in the x - y axis, so our ground plane should be parallel to this axis. 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. Now we want to add a fixed 'ground' object to our simulation. BRL-CAD is a constructive solid geometry (CSG) solid modeling computer-aided design (CAD) system.
