History of BRL‑CAD

In 1979, the U.S. Army Ballistic Research Laboratory (BRL) – now the United States Army Research Laboratory – expressed a need for tools that could assist with the computer simulation and engineering analysis of combat vehicle systems and environments. When no CAD package was found to be adequate for this purpose, BRL software developers – led by Mike Muuss – began assembling a suite of utilities capable of interactively displaying, editing, and interrogating geometric models. This suite became known as BRL-CAD. Development on BRL-CAD as a package subsequently began in 1983; the first public release was made in 1984. BRL-CAD became an open-source project on December, 2004. The BRL-CAD source code repository is believed to be the oldest public version-controlled codebase in the world that's still under active development, dating back to 1983-12-16 00:10:31 UTC.

Documenting Redux

Microsoft ended official support for Office 2019 on October 14, 2025 . Using unsupported versions from unknown sources increases your vulnerability to security threats. Why Choose the 64-bit Version?

Before the rise of sophisticated content management systems (CMS) and search engines, web servers (like Apache or Nginx) often displayed a simple, text-based "index of" page when no default file (like index.html ) was present. These pages looked like this:

Direct downloads from unauthorized directories violate licensing agreements.

Microsoft Office 2019 is a "one-time purchase" version of the productivity suite, distinct from the subscription-based Microsoft 365. The 64-bit version is preferred for users working with large data sets (like massive Excel spreadsheets) or complex graphics, as it can access more system memory than the 32-bit version.

BRL‑CAD Logo Competition!

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. That said, you can double your prize amount IF (and only if) you design a selected logo only using BRL-CAD tools. See here for an example of what I mean. If you're going for the bonus, submit a ".g" geometry file in addition to any image file(s) you provide. In case you're wondering, shoving an image into a .g doesn't count! 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. The BRL-CAD "mascot" is a moose. Feel free to incorporate that into your design or come up with something more abstract. Other keywords relevant to our project domain are listed in this file.
