Adding callbacks should make the program more flexible allowing user to choose between various situations. Having the above stated two fixed user callbacks will be added. It is easier to resend the package that hasn't been received than to check each package. For example, if we implement a Cyclic redundancyi check field in our package header on a very fast network there is a direct loss in performance. Performance bottlenecks should be detected when using the above stated tests. This would be a very basic way of obtaining loss rate (lost packages / total packages sent). When a package timer expires the package is resent, the lost package count is increased and the timer is reset. I have used the “gettimeofday()” time stamp difference to simulate a package timer. Packages passed around will be compared md5sum in order to ensure consistency is maintained. Parameters tested could include speed, delay, corruption and package loss as well as a general record of this parameters for different package sizes. First one consists of implementing a testing framework. The Package Library Extensions project can be split in three parts. The original implementation in BRL-CAD is a good starting point, and I will take the current routines of BRL-CAD. Finally, I'd like to build a converter that can walk a CSG tree and convert the implicit primitives in the tree altogether to their NURBS form. This summer, if I'm accepted, I'm going to accomplish the goal of converting all (if needed) implicit primitives to NURBS, including fixing the bugs and correcting the errors existing now, and adding new conversions that have not been implemented yet. Lots of primitives have already been implemented as NURBS, but some are not robust and some still need to be improved. So we need a conversion to NURBS bundary representations. The reduction must be very careful in order not to disrupt the project, so different unit tests will be necessary after reduction.Īt present, BRL-CAD has implemented lots of geometric primitives in an implicit form, but when it comes to interactive shaded displays and conversion to other formats, the disadvantages of implicit primitives come out. Such refactoring is necessary for reduced maintenance cost.

Code Refactoring for Reduced Maintenance CostĪs there are many "copy-pastes", the main aim of this project is removing of duplications and decreasing in the count of lines of the BRL-CAD project.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. 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.
