![]() Greatest strength is that anyone can get involved and directly contribute. As free open source software, one of BRL-CAD's Week, seven individuals from four different countries, three continents, and one oceanic island producedĪ book for BRL-CAD totaling more than 100 pages in length. ![]() Teams for GNOME, OpenMRS, and BRL-CAD arrived on the GoogleĬampus and talked at length about techniques, tools, formats, documenters, and more. ![]() Unconference brainstorming stickies A team of individuals traveledįrom around the world to the Google headquarters in Mountain View, California, to participate in a 2-partĮvent: an unconference and a book sprint. Over the course of a week in October, members from our community participated ![]() There are literally thousands of features. In all, BRL-CAD has more than a million words of documentationĪcross hundreds of manual pages, dozens of tutorials and examples, hundreds of wiki pages, dozens of To and perhaps because of longstanding efforts, people interested in improving BRL-CAD sometimes find BRL-CAD doc team getting to work writing a bookįrom scratch in less than three days. A team of contributors got together in California,īrainstormed, and wrote an entire book for BRL-CAD in just a few days. VariousĬonverters including the STEP, Patch, and 3DM importers received robustness improvements.īRL-CAD was selected to participate in the 2013 Google Summer of Code Doc Camp. Interface deprecation policy (see CHANGES file), the Jove text editor is no longer being bundled. This release also includes various improvements to BRL-CAD's ray tracing infrastructure includingĬPU thread affinity locking for faster performance, more consistent grazing hit behavior, expanded volumeĪnd surface area calculations, numerous bug fixes, and more robust NURBS evaluation. On stability and usability, this alpha status solicits feedback from the community on capability andįeatures. Prior to upcoming beta testing where the emphasis is predominantly Software, this new MGED prototype aims to provide functional feature parity with the antecedent MGED Some highlights include an integrated graphical tree view, a single windowįramework, drag and drop geometry editing, information panels, shortcut buttons, improved polygonal meshĪnd 2D sketch editing, level of detail wireframes, NURBS shaded display support, and much more. The bearing is modeled with a material appearance resembling acrylic glass, and this raytracing result shows reflection, refraction, shadowing, and some caustic effects.Īs shown, a BRL-CAD target description can be converted to a finite element mesh (FEM) using the BRL-CAD g-sat exporter and Cubit from Sandia National Laboratories.īRL-CAD provides a comprehensive procedural geometry interface as a means for creating models algorithmically instead of manually.Īfter nearly an entire year's worth of intense collaborative effort, the 7.24.0 major release of BRL-CAD is now availableįor download! This is the alpha release unveiling of Archer/MGED, a preliminary interface update to BRL-CAD's The image shown is a BRL-CAD 2D framebuffer screenshot displaying the rendering of a ball bearing. 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. This model was created by students new to BRL-CAD in the span of about 2 weeks, starting from actual measurements in a museum. Shown is a 3D model of a Goliath tracked mine, a German-engineered remote controlled vehicle used during World War II. Solid modeling is distinguished from other forms of geometric modeling by an emphasis on being physically accurate, fully describing 3D space.
