This project aims to provide more channels to the users to submit the benchmark logs of their brlcad installations ( via the web API, ftp, scp in addition to the existing channel of email), implement an efficient storage and retrieval of logs (via the database and the archiving of the files) and provide an interface to access the logs via graphical means or otherwise. Our goal is to become the best solid modeling system by encouraging worldwide collaboration, improving recognition and awareness, providing effective user-friendly features, and by continuing to work hard at catering to our users' needs. See our industry diagram for a visual overview of where BRL-CAD fits within the various CAD industries. ![]() BRL-CAD's primary competitors are in an entirely separate industry where commercial products like AutoCAD, Solidworks, Pro/Engineer, and CATIA dominate. Our organizational interests in BRL-CAD vary across the project's primary focus areas including CAD, CAM (manufacturing), CAE (engineering), solid modeling (analysis), and computer graphics.īRL-CAD's users are primarily composed of individuals in the CAD industry where modeling requirements are fundamentally different from those of content modelers (such as Blender) that are used for animation, gaming, and film purposes. The BRL-CAD community is represented and developed by a consortium of individuals in the open source community from industry, academia, government, and private industry all over the world. BRL-CAD became an open source project in 2004. It's more than a million lines of code, 400+ binary applications, dozens of libraries, and has been under development for more than 25 years. Specify paths to headers, source file(s), paths to libs, and then the libs need:Ĭ++ -I/opt/brlcad/include -I/opt/brlcad/include/brlcad -I/opt/brlcad/include/openNURBS test.Google Summer of Code 2012 BRL-CAD businessīRL-CAD is a powerful cross-platform open source solid modeling computer-aided design (CAD) system.īRL-CAD provides solid geometry editing, ray-tracing, geometric analysis, image and signal-processing, performance analysis tools, a robust high-performance geometry engine, and much more. ![]() If we already installed BRL-CAD into /opt/brlcad and want to use all headers and all the core libraries, the process remains the same. To find functions, we can browse around the headers and subdirs in the include directory as nearly every public function is documented in detail there with comments, often with code snippet examples too. If we want to link against another library like LIBRT or LIBGED, we already have the right paths so we'd simply add -lrt or -lged respectively to the link line. Woot! If you didn't confuse l with 1, put the wrong path, or mix something else up, you should see:Īnd that's essentially all there is to it! We can even simplify the entire process into one compile+link command if we are careful enough to make sure include flags come before source files and linker flags come after the source files in the right order:Ĭ++ -Iinclude -I.build/include test.cpp -L.build/lib -Wl,-rpath -Wl.build/lib -lbuįrom there, we set up to use any function in LIBBU. (You don't need to install to use any library - you just need to know where to find headers and libs!) After changing directory to ~/brlcad, we can compile, link, and run our little test program:Ĭ++ -c -Iinclude -I.build/include test.cppĬ++ test.o -L.build/lib -Wl,-rpath -Wl.build/lib -lbu So say we put that test.cpp file in ~/brlcad and have BRL-CAD compiled at ~/brlcad/.build but not installed. For gcc/clang, this is usually an -rpath linker option.To run, you need to specify run paths to libraries (so it can use functions).For gcc/clang, this is usually -L options and -l options.To link, you need to specify paths and libraries to link (so it can find functions). ![]() For gcc/clang, this is usually -I options.To compile, you need to specify paths to headers (so the #include lines work).No matter what compiler or operating system you use, there are options for all three of those: Std::cout << "Program name is " << bu_getprogname() << std::endl īuilding software involves compiling source code, linking objects, and running our application. Say you have a simple C++ source file named test.cpp using LIBBU, BRL-CAD's basic utility library: Compiling against any of BRL-CAD's 20+ libraries is generally quite straight forward.
