+ 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 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. In contrast to many other 3D modelling applications, BRL-CAD primarily uses CSG rather than boundary representation. 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.
+
+
The BRL-CAD libraries are designed primarily for the geometric modeler who also wants to tinker with software and design custom tools. Each library is designed for a specific purpose: creating, editing, and ray tracing geometry, and image handling.
+ 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.
+
+
+
+
+
+
+
+ History and Vision
+
+
+
+
+
+ BRL-CAD was originally conceived and written by the late Michael Muuss, the inventor of the popular PING network
+ program. In 1979, the U.S. Army Ballistic Research Laboratory (BRL) (the agency responsible for creating ENIAC, the world's first general-purpose electronic computer in the 1940s) identified a need for tools that could assist with the computer
+ simulations and analysis of combat vehicle systems and environments. When no existing CAD package was found to be adequate for this specialized purpose, Mike and fellow software developers began developing and assembling a unique suite of
+ utilities capable of interactively displaying, editing, and interrogating geometric models. Those early efforts subsequently became the foundation on which BRL-CAD was built.
+
+ Development of BRL-CAD as a unified software package began in 1983, and its first public release came in 1984. Then, in 2004, BRL-CAD was converted from a limited-distribution U.S. government-controlled code to an open source project, with portions licensed
+ under the LGPL and BSD licenses.
+
+
+ Today, the package's source code repository is credited as being the world's oldest, continuously developed open source repository. As a project, pride is taken in preserving all history and contributions.
+
+
+ The ongoing vision for BRL-CAD development is to provide a robust, powerful, flexible, and comprehensive solid modeling system that includes:
+
Comprehensive conversion support for all solid geometry formats.
+
Effective geometric analysis tools for 3D CAD.
+
+
+
+
+
+
+
+ Key Strengths
+
+
+
+
+
+ All CAD packages are not alike. Among the many strengths of the BRL-CAD package are the following:
+
+
BRL-CAD is open source! Don't like something? You can make it better.
+
You can leverage decades of invested development. BRL-CAD is the most feature-filled open source CAD system available, with hundreds of years time invested.
+
Your work will get used. BRL-CAD is in production use and downloaded thousands of times every month by people all around the world.
+
You have the ability to create extensively detailed realistic models.
+
You can model objects on scales ranging from (potentially) the subatomic through the galactic, while essentially providing all the details, all the time.
+
You can leverage one of the fastest raytracers in existence (for many types of geometry).
+
You can convert to and from a wide range of geometry file formats.
+
BRL-CAD has a powerful, customizable scripting interface with many advanced editing and processing capabilities.

Boundary Representation
+
+
Boundary representation NURBS surface geometry is one of the dominant geometric representation formats in CAD. BRL-CAD is one of the few 3D solid modeling systems that not only support geometry in boundary representation NURBS format but also provide extensive support for robust solid ray tracing of NURBS geometry. The image shown is the classic computer graphics Utah teapot model prepared for 3D printing and rendered via BRL-CAD ray tracing.

Path Tracing
+
+
Representing more than 8 trillion rays fired at this 11-million-polygon scene (amounting to more than 20 million rays per second on 2004 hardware), this figure signifies the path tracing capability of BRL-CAD. A full light simulation was computed to generate the image with all exterior and interior vehicle detail, including every nut, bolt, wire, and component inside the vehicle and every leaf and blade of grass modeled as actual geometry (with no textures and no procedural geometry).

Raytracing
+
+
Raytracing is central to BRL-CAD as a means for performing geometric analysis (e.g., calculating weights and moments of inertia) and for rendering images for visualization purposes. The image shown is a BRL-CAD 2D framebuffer screenshot displaying the rendering of a ball bearing. The bearing is modeled with a material appearance resembling acrylic glass, and this raytracing result shows reflection, refraction, shadowing, and some caustic effects.

Solid Geometry
+
+
BRL-CAD focuses on solid modeling CAD. Solid modeling is distinguished from other forms of geometric modeling by an emphasis on being physically accurate, fully describing 3D space. Shown is a 3D model of a Goliath tracked mine, a German-engineered
+ remote controlled vehicle used during World War II. This model was created by students new to BRL-CAD in the span of about 2 weeks, starting from actual measurements in a museum.

- After nearly an entire year's worth of intense collaborative effort, the 7.24.0 major release of BRL-CAD is now available
- for download! This is the alpha release unveiling of Archer/MGED, a preliminary interface update to BRL-CAD's
- graphical geometry editor. Some highlights include an integrated graphical tree view, a single window
- framework, drag and drop geometry editing, information panels, shortcut buttons, improved polygonal mesh
- and 2D sketch editing, level of detail wireframes, NURBS shaded display support, and much more. As alpha
- software, this new MGED prototype aims to provide functional feature parity with the antecedent MGED
- interface while introducing changes. Prior to upcoming beta testing where the emphasis is predominantly
- on stability and usability, this alpha status solicits feedback from the community on capability and
- features. This release also includes various improvements to BRL-CAD's ray tracing infrastructure including
- CPU thread affinity locking for faster performance, more consistent grazing hit behavior, expanded volume
- and surface area calculations, numerous bug fixes, and more robust NURBS evaluation. Following BRL-CAD's
- interface deprecation policy (see CHANGES file), the Jove text editor is no longer being bundled. Various
- converters including the STEP, Patch, and 3DM importers received robustness improvements.
