In addition to emitting the tcl script, it runs mged to create a new geometry database, and then converts that to an STL. The multi-part example shows how to use two python-brlcad-tcl objects (including motor_28BYJ_48_example.py). note that motor_28BYJ_48_COMPLETE1.r here is the 'region' that was created at the end of the motor's init function, it is a special type of combination that 'instantiates' all of the non-region 'object definitions' (primitives and combinations).python -m examples.motor_28BYJ_48_example output.tcl.An example of a 28BYJ-48 stepper motor, run with: 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. 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. In contrast to many other 3D modelling applications, BRL-CAD primarily uses CSG rather than boundary representation. 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. 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. The BRL-CAD libraries are designed primarily for the geometric modeler who also wants to tinker with software and design custom tools. 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. 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. BRL-CAD is a constructive solid geometry (CSG) solid modeling computer-aided design (CAD) system.
