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. 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.
This means BRL-CAD can "study physical phenomena such as ballistic penetration and thermal, radiative, neutron, and other types of transport".
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.
The BRL-CAD source code repository is the oldest known public version-controlled codebase in the world that's still under active development, dating back to UTC. Among the thousands of features in BRL-CAD, here are some additional capabilities that are central to our project ethos.
There are a number of features aimed at inspecting, preparing, verifying, and validating geometry models. Single-ray sampling can be used for measuring thicknesses or distances, and certain 3D analyses are possible such as calculating volume, centroids, and moments of inertia.
BRL-CAD also has numerous facilities for detecting and resolving assembly or part interferences where two objects spatially overlap each other. Considerable attention has been put into in-memory and on-disk data storage efficiency. BRL-CAD is capable of handling complex geometry models that are often impossible to open with other systems without changing hardware requirements.
BRL-CAD's ray tracing infrastructure is one of the fastest in the world for implicit geometry representations and is continually seeking performance advancements for other explicit representation types, such as polygonal mesh geometry and NURBS surface models. BRL-CAD's distributed ray tracing support is recognized as the world's first "real-time" ray tracing implementation, achieving several frames per second in the s.
Symmetric Multi-Processing BRL-CAD efficiently leverages symmetric multi-processing SMP capabilities of desktop, server, and supercomputing systems, where an arbitrary number of processing cores can be put to work on a computational task.
BRL-CAD's ray tracing library is commonly leveraged for performing highly detailed geometric analysis, driving third-party simulations, and producing animations.
Modular Architecture As a large software package developed over a relatively long period of time, BRL-CAD has necessarily been designed and evolved with modularity in mind. Functionality is implemented across hundreds of application modules, commands, and libraries designed to work together. Hundreds of application binaries work together supporting efficient customizable workflows. Core geometry editing capabilities are implemented as commands that can be easily extended, replaced, or improved upon.
All functionality and features are built on top of a core set of libraries that encapsulate common capabilities. One of the best ways to get involved is to add a new module or improve an existing one.
Today, BRL-CAD's hardware support includes everything from minimal laptops and desktops to gigantic distributed supercomputers. We aim to be "embarrassingly portable. As free open source software, one of BRL-CAD's greatest strengths is that anyone can get involved and directly contribute. You can make it better.
This new book focuses on that aspect and introduces people to the project while providing detailed information for developers, writers, artists, and other potential contributors. This guide will be available on a website at a later date in electronic and printed form.
Attending the camp provided an exciting opportunity to get a grasp on new techniques for documenting and sharing information about our software, hopefully in ways that help us grow our community. The BRL-CAD open source project is interested in a new logo so we're holding a competition for inspiring ideas from the community!
You have the chance to win cold cash, make friends, and obtain world-wide notoriety. There are cash prizes for first, second, and third place selections plus an optional bonus. Winning selections will be announced by August 15th.
Pen and paper work just fine. Scan it in and e-mail it. You're welcome to use any tools or software to design the logo. See here for an example of what I mean. If you're going for the bonus, submit a ". In case you're wondering, shoving an image into a.
With our steep learning curve, though, it's definitely not for pansies nor recommended if you're a newbie. The bonus is just for the added awesome factor.
