Welcome to the BRL-CAD community publication portal. This page is dedicated to the preparation and editing of community publications for BRL-CAD. Proposed and upcoming publications are listed with their individual editorial status. You are welcome and encouraged to help share news about recent events or current activities taking place within the BRL-CAD community by writing an article. Community editing is welcome.
Formatting & Editing Standards:
For release publications, follow HACKING. For everything else, distribute to the following:
These are articles ready for publication. Release notes should follow a release and get published within the first week of the month. Other publications should be scheduled one or two weeks later, ideally on the third week of the month.
Note: if you see a comment indicating that a section is FROZEN, any changes you make in that section may go unnoticed as the article is being prepared for distribution. If you find errors in a FROZEN article, go ahead and correct the article but contact Sean (brlcad on freenode IRC) who may be able to incorporate changes during final publication.
BRL-CAD has been accepted to participate as a mentoring organization in the European Space Agency's Summer of Code in Space! Modeled after the Google Summer of Code, SOCIS is an ESA pilot project offering students the opportunity to get paid developing space-related Open Source software. Interested students should apply soon, before the July 27th deadline.
Students from higher-education institutions within the European Union propose space-related BRL-CAD software development projects and, if selected, receive a €4000 EUR (approx. $5750 USD) stipend over a three month timeframe (Aug-Oct) to work on their projects. Eligible students  interested in applying should visit our project ideas page . As this is a pilot program, it's being conducted very quickly, so applications must be submitted  to the ESA by July 27, 11AM (UTC)!
BRL-CAD is one of only 20 organizations selected to participate in SOCIS. BRL-CAD has a history of involvement in space-related projects including astronomical visualization, concept spacecraft modeling, image analysis, signal processing, and more. By participating, we hope to improve BRL-CAD's usefulness for space-related projects by improving usability. Many thanks to the ESA administration and Open Source supporters within the ESA for establishing such a fantastic program!

These should be "complete" articles. The author is done with the content and all that remains is a review of structure, grammar, voice, punctuation, and spelling. Images may be added as well.
Ronja (Reasonable Optical Near Joint Access) is an innovative piece of equipment that utilizes reliable optical data links to create a current communication range of 1.4 km and a speed of 10Mbps full duplex that can be used as a general purpose wireless link for virtually any networking project. This is a very important project for Twibright Labs, a small group of computer science graduate students operating out of Charles University in Prague in the Czech Republic. The group specializes in the usage of Free Software and User Controlled Technology Development.
The primary output for the Ronja project is a design. The lab does not intend to manufacture and sell the hardware that is being designed but wants to engage in open source development of the technology. The philosophy surrounding User Controlled Technology is the ideal that the end-user is provided with unrestricted access to the intellectual property surrounding the technology, including the tools that are being used to create it. One tool playing an integral part in the development of the Ronja designs is BRL-CAD. All of the models that Twibright labs use to display the different variants of their Ronja concept were created with the help of BRL-CAD. BRL-CAD has allowed the members of Twibright labs to create instructional diagrams so that the users and builders of their open source technology will be able to have the latest information with regard to the proper construction of a Ronja unit. The interactive geometry editor and ray-tracers in BRL-CAD are an integral part in the communication of design plans for Twibright labs and enables them to connect with the users, who are the driving force behind the User Controlled Technology ideal.
These are incomplete articles being worked on. Most articles should be between 250 and 500 words (not counting tables, labels, and diagrams) before they have enough content to be considered complete.
Over the past year, an intense development effort by BRL-CAD's development team has successfully implemented raytracing of Non-Uniform Rational BSpline (NURBS) geometry within the BRL-CAD Computer-Aided Design (CAD) package. NURBS surfaces are very general, very complex mathematical shapes used by virtually all modern commercial CAD software packages. Because BRL-CAD did not originally support this type of geometry, commercial models could only be imported into BRL-CAD after a labor-intensive and difficult conversion process from NURBS form to triangle-base geometry (referred to in BRL-CAD as Bags-of-Triangles or BoTs). The new NURBS raytracing capability builds on work by many developers over a period of years, who in turn built on the open source library OpenNURBS. Support for this primitive type means BRL-CAD can now store and raytrace data from commercial models without requiring preliminary conversion to another type of geometry.
The last major feature needed to make import of commercial models in BRL-CAD straightforward is conversion support for ISO’s "Standard for the Exchange of Product model data" or STEP file format. STEP uses NURBS geometry in its definition, making support for NURBS geometry a necessary prelude to support for STEP import. Most commercial CAD modelers support this file format as an output option, hence STEP support in BRL-CAD would allow a direct path for moving geometric descriptions from a variety of commercial modelers to BRL-CAD. Considerable progress has already been made on STEP import support, but more work is need to bring the code and feature set to "production quality". If anyone would like to join the BRL-CAD open source development effort and has a little familiarity with C++, the step-g converter and its supporting libraries have some simple-yet-useful tasks that would be an excellent and very useful way to explore the project - join BRL-CAD's IRC channel or development email list if you are interested!
