=== Add MGED key-binding to reopen the command window ===
 +
 +
BRL-CAD has an interactive geometry editor called MGED. It's often the starting point for beginners and allows creation and manipulation of models using commands. When MGED is invoked, it creates 2 windows:  a text-console command window and an interactive graphics window.  If the user closes the text-console command window, they are left with the interactive graphics window.  There is presently no way (correct us if we're wrong) to get the text-console back without restarting mged.  A good way to test this is to run in classic mode and run the 'gui' command:

This task involves adding some mechanism, perhaps a simple key binding, to the graphics window so that you can get the command window back on-demand.

BRL-CAD provides more than two dozen types of geometry "primitives" such as ellipsoids, boxes, and cones.  Every primitive is described by a collection of callback functions, for example rt_ell_bbox() returns the bounding box dimensions for an ellipsoid.  Wikipedia, Wolfram Mathworld, and various other math sites (and research papers) around the web include the equations for most of our basic primitives while others are a little more tricky to compute.

BRL-CAD provides more than two dozen types of geometry "primitives" such as ellipsoids, boxes, and cones.  Every primitive is described by a collection of callback functions, for example rt_ell_bbox() returns the bounding box dimensions for an ellipsoid.  One of those functions describes a UV mapping of the object's surface, which is used for things like texture and bump mapping.  An example of this is rt_ell_uv() in the src/librt/primitives/ell/ell.c source file for an ellipsoid.  Several of our more complex primitive types (such as BoT, NMG, and BREP/NURBS) do not presently implement a UV-mapping function leading to unexpected runtime behavior.

There are platform specific sort functions qsort_r() in incompatible versions for BSD and GNU and qsort_s() for MSVC.  Your task is to implement a bu_sort() function for BRL-CAD which is platform independent.

BRL-CAD has been working on a new incarnation of the website and has developed a new wiki theme and wordpress theme. Wiki theme uses a font called 'open-sans' from google fonts directory. It's linked via CSS but it does not get loaded (we still see default serif all over the place). So your task will be to debug the CSS code and get Open Sans loaded.

=== Write an article "BRL-CAD for dummies" ===
+
=== Document MGED's 'saveview' command options ===
  
Although BRL-CAD has extensive documentation, still it needs a short and simple document which is particularly built for dummies.
+
BRL-CAD's primary geometry editor (MGED) provides hundreds of commands.  Two of those commands are the savewview and loadview commands that write current view settings out to a text file and read them back in.  The saveview command provides -e -i -l and -o options, but they are not documented.
  
This task involves writing a article named '''BRL-CAD for dummies'''. This article should start with the installation process, if there is any existing installation guide for dummies, provide a link to it. The main motive of this article to empower dummy to make his/her first model using BRL-CAD. One thing to be kept in mind while writing this article is that this article is mainly concentrated for dummies. So use simple language to an extent and if you need to mention some technical term, first explain that term.
+
This task involves writing documentation for those missing options. Consult the source code to see what they do and add the corresponding sections into our Docbook XML doc just like we do in our other documentation files. Test compilation to make sure your XML syntax is correct.
  
The output of this task can be a pdf, html, doc, odt or any other document file that contains this article. Go through the link provided. Use screenshots and images to make it look attractive so that the reader is not bored.

=== Translate "Contributors Guide To BRL-CAD" To Any Language ===
 
 
 
People interested in improving BRL-CAD sometimes find themselves lost in a sea of information. In all, BRL-CAD has more than a million words of documentation across hundreds of manual pages, dozens of tutorials and examples, hundreds of wiki pages, dozens of technical papers, and other resources. There are literally thousands of features and this can sometimes pose problems.
 
 
 
In 2013, a team of contributors got to California and worked on an entire book titled "Contributors Guide To BRL-CAD" in just a few days. This great resource needs to be translated to other languages to attract developers from other lingual backgrounds (who don't read English ) to contribute to BRL-CAD.
 
 
 
This task involves translating the chapters/sections of the "Contributors Guide To BRL-CAD" into a language of your choice such as Mandarin, French, Chinese, Spanish, German, Hindi, Arabic, Russian, etc. Chapters/Sections include
 
 
 
* Feature Overview
 
* Working with our Code
 
* What code to work on
 
* How to contribute
 
* .... (Just to name a few )
 
 
 
The output of this task can be a pdf, html, doc, odt or any other document file that contains the translated article.Images in the original document (see link in Reference below) should not be changed ! only text should be.

=== Write a manual page for MGED's "brep" command ===
 +
 +
BRL-CAD's MGED geometry editor provides hundreds of commands.  One of those commands for manipulating and visualizing geometry is the "brep" command.
 +
 +
This task involves writing a manual page for that command in the Docbook XML format.  There are lots of examples to follow.
 +
 +
References:
 +
* doc/docbook/system/mann/en/*.xml
 +
* http://brlcad.org/wiki/Documentation (contains intro to mged and cheat sheets)
 +
* bin/mged  (you'll need to run this to use the "brep" command)
 +
* bin/csgbrep  (will create a slew of 'brep'/nurbs objects for the "brep" command)
 +
 +
Code:
 +
 +
* doc/docbook/system/mann/en/brep.xml  (you write this)
 +
* doc/docbook/system/mann/en/CMakeLists.txt  (you edit this)
 +

=== Make a step by step tutorial for creating BRL-CAD model ===
 
  
BRL-CAD is said to have an expert friendly User Interface so new users mostly have a tough time getting around it's UI and making models. So anything link Django poll app tutorial https://docs.djangoproject.com/en/dev/intro/tutorial01/ would be very helpful.  
+
=== Investigate permuted vertex lists from g-iges + iges-g ===
 +
 
 +
BRL-CAD has a geometry exporter and importer for the International Graphics Exchange Standard (IGES) file format.  If you run our g-iges exporter on some geometry, then run iges-g on that same geometry to import it back to BRL-CAD format, the geometry will have permuted vertex lists.  Particularly for geometry already in polygonal format, such as our NMG or BoT geometry, this conversion should result in identical geometry but presently does not.
 +
 
 +
This task involves investigating why this occurs, reporting (in detail) why it occurs, and if obvious, making a recommendation on how to fix the problem.

Online Geometry Viewer is a web based application with which you can see 3D .g models in browser without the use of any plugins. Your task will be to deploy OGV locally and find 5 bugs or errors in it.  
+
We've been working for several years on "code hardening", improving the quality of BRL-CAD's source code through a variety of best practices and code cleanup efforts.
  
Links:
+
This task has you write an article that succinctly summarizes all of our efforts.  You'll need to become familiar with our HACKING file as well as read up on our various hardening efforts. You're welcome to ask our devs questions over IRC for more information too.

=== Profile NURBS prep performance ===
+
=== Write an article soliciting a Windows platform maintainer ===
  
BRL-CAD implements support for rendering of NURBS representation geometryIf you import a solid 3DM or STEP format model into BRL-CAD, it will import as BREP/NURBS geometryOpening that geometry in BRL-CAD's MGED editor will tell you what objects are available and our 'rt' tool will raytrace it.  When geometry is ray traced, it first goes through a "prep" phase and then it starts shooting raysOur prep phase is entirely unoptimized so we'd like to know where all the time is presently being spent during prep..
+
BRL-CAD runs on a number of platforms and distributes releases many times a yearCreating a release for any particular binary platform, like Windows or Mac OS X or Linux, is delegated to a "release maintainer".  We currently have maintainers for a number of platforms but do not have one for WindowsBasically, it's a volunteer job, it's a lot of work, but not very hard and very rewardingThere are thousands of binary downloads every month, so lots of people benefit from a maintainer's efforts.
  
This task involves importing some NURBS geometry into BRL-CAD and ray tracing that geometry with a profiler watching our prep performanceAny profiler will do, including gprof, but a performance monitor like oprofile or the Mac "Instruments" application (or Shark) are preferred.
+
This task involves writing a brief solicitation article announcing our interest for a maintainer, describing the responsibilities involved, and telling them how to take up this responsibilityCome talk to us on IRC for more specific details.
  
Learning how to use a profiler is beyond the scope of this task, so it make take you considerably longer to provide us with useful information if you've never run a profiler before.
+
Resources:
 +
* http://svn.code.sf.net/p/brlcad/code/brlcad/trunk/HACKING
 +
(See the release section near the bottom to see what maintainers do)
  
To capture prep performance, you will need to import some fairly complex geometry.  You should be able to search google with "filetype:3dm" or "filetype:step" or find something on grabcad.com to import
+
Add the article to http://brlcad.org/wiki/Community_Publication_Portal
 
 
Running "tops" within mged will tell you what geometry is available for rendering.
 
  
Running "rt -o file.png -s32" on the system command line (not inside mged) should minimize the ray overhead or you can specifically isolate the prep phase we care about.  Prep is the time between when rt is run where it opens a window until the first pixels are fired and pixels start filling in.

=== Continue investigating GMP integration ===
+
=== Create an ISST screenshot or animation ===
  
BRL-CAD uses a fastf_t typedef for most all math operations that is usually a "double" floating point type. We would like to provide the option for resorting to exact arithmetic if possible by merely redefining fastf_t to a C++ type sufficiently overloaded to behave the same. You should be proficient with C++ operator overloading to take this work on. This task is a continuation of a prior GCI task (read it in full!):
+
Everyone loves to see screenshots and animations of software in action. We use both in our marketing and outreach. See some of the examples below that we already have.
  
http://www.google-melange.com/gci/task/view/google/gci2012/7946218
+
Create an awesome screenshot and/or animation of our 'isst' tool in action. It's an interactive geometry viewer interface.  It should be graphically interesting and give some sense of capability. You should import a visually complex and interesting model with LOTS of polygons and detail.
  
This task involves testing compilation with a C++ class with overloaded operators such that vmath macro calls still work as well as a sampling of LIBBN API function calls without major changes to the original code. A perfect example case study would be creating the class then testing whether bn_dist_pt3_pt3() and bn_mat_determinant() compute correctly for values that cannot be exactly represented with floating point arithmetic.
+

Building on the previous GCI task work, take it to the next step. Try setting a vector to 1/3, 1/3, 1/3 and 0.1, 0.1, 0.1 and get proper values to print. Change the V3ARGS() macro if needed. If that all works, try to get bn_dist_pt3_pt3() to work.  Report and discuss your progress.

=== Design a coffee mug for BRL-CAD ===

=== Model BRL-CAD logo in BRL-CAD ===
 +
 
 +
The BRL-CAD Logo depicts two interlocked nodes. Modeling the new Logo in BRL-CAD in CSG (without NURBS, without polygons) requires some careful arrangement, but can provide an attractive three dimensional rendering that we can use for a number of purposes..
  
This task involves designing a coffee mug for BRL-CAD. Make it look good, so that one can use it while working on BRL-CAD. Look over some great coffee mug designs before starting to work on this. It would be great if the design on coffee mug has some special meaning.
+
The output of this task will be a .g file of BRL-CAD logo and a rendered image. The two segments you model MUST be two or more regions, ideally hinged together (you can have center pins or not, you decide). This is your opportunity as an artist and 3D magician to come up with an interesting yet faithful interpretation.

This task involves designing a BRL-CAD sticker. The design should be simple and sleek. The concept of sticker should be clear and also it should be creatively presented. Get inspired from some sticker designs but choose your own imagination while designing the sticker. There is no bound for shape of sticker, it can be rectangular, circular or even irregular. The only thing that matters is that it should look good.

=== Design a prototype CAD GUI layout ===
 +
 +
BRL-CAD's usability is notoriously complex and "expert friendly". MGED and Archer are the main geometry editors, with drastically different user interfaces.
 +
 +
This task involves evaluating the features provided by MGED and Archer, then designing a new GUI layout that encompasses their features while improving usability. Rationale for design decisions and layout should be provided.
 +

 +
Provide one or more mock-up images (png, pdf, psd, html, whatever)
 +
 +
Search for other similar GCI tasks to avoid making a similar design.  You can use any tools, but your work must be original.

=== Design a Cover Photo for Facebook page (and other social networks) ===
+
=== Redesign MGED/Archer's Menu ===
  
BRL-CAD got it's logo changed, and it's website is undergoing a change. So this re-branding of BRL-CAD also requires a good, well designed and attractive cover photo for the BRL-CAD's Facebook page or other Social Media Appearances. It should feature a good tagline telling some killer feature of BRL-CAD, BRL-CAD's new logo and/or some illustration/image regarding the feature highlighted in tagline.
+
BRL-CAD's geometry editing applications, like most graphical applications, have an application menu with a variety of features, capabilities, and options, but with little attention to cohesive design.
  
It should be consistent with the color scheme of our new website design.
+
Review the menus for MGED and Archer.  Design a new menu system based on both of them that eliminates confusion, is easier to navigate, and has menu options more logically grouped together.

===  Design a banner ad for BRL-CAD ===
 
 
 
BRL-CAD is one of the oldest open source communities. This community has a good following, so we want to give a chance to everyone so that they can show their support to the community by adding a banner ad in their website. You have to create a banner ad that can be embedded in the website by copy pasting some simple lines of code (basically an iframe).
 
 
 
Such a banner ad can also be used in various sections of our own website.
 
 
 
The task requires you to create a CSS3 based animated horizontal and vertical banner add, highlighting some feature of BRL-CAD or making some call to action. This call to action can be joining mailing list, or signing up for community, or link to latest post etc.
 
  
For Inspiration and tutorial refer

Provide screenshots or detailed text indicating what menu options should be available and what exactly is on each menu.

+
=== Create Wordpress theme for BRL-CAD website ===
  
BRL-CAD has a lot of great features that can be highlighted. A motion typography video highlighting these features would be a wonderful addition to the front page of website.  
+
BRL-CAD's website was recently redesigned.  The current website uses Drupal and Mediawiki. Our new website will be using Wordpress and Mediawiki.
  
This task requires you to create a motion typography video that will convince user to give BRL-CAD a try, it could be titled something like "x reasons to choose BRL-CAD" or anything similar (give your creative minds a flight). The video should not be more than 2 minutes.  
+
This task involves creating a custom Wordpress theme based on our new website design.

=== Create a screen-cast for BRL-CAD  ===
+
=== Migrate Drupal site to Wordpress ===
  
Getting started with BRL-CAD is sometimes not so smooth. A screen-cast giving a tour of BRL-CAD's GUI and the steps involved in creating the first model will make it easy for users to get started.  
+
BRL-CAD's main website content runs on Drupal. There are a lot of articles, user accounts, and other information contained within this installation of Drupal.
  
For this task you need to install BRL-CAD on your computer. Create a very basic model in it and record your screen as you create the model. It should also give a tour of BRL-CAD's workspace. You can choose model of your choice. Keep something very basic and easy for the first time users.
+
This task involves setting up an installation of Wordpress on our production server and migrating the data from Drupal into the Wordpress site.

=== Loading Google charts from API  ===
 
 
 
A basic wrapper of GCharts has been implemented a while ago : https://bitbucket.org/suryajith/benchmark/src/a27dd8c05d6819a527650e06a63076599d2e0d66/libs/charting.py?at=default With the google charts improving their API system which wasn't around then, see if the code could be optimized so to get the charts the optimal way.

=== Design a hall of fame for BRL-CAD developers ===
 
 
We love our developers and want to have a special place in it's website to thank and motivate hard working folks behind BRL-CAD. Your task would be to use an image manipulation software such as GIMP or Photoshop and design a hall of fame page for developers. It should have avatars and names of all the developers. For inspiration you can take a look at http://underscores.me/. You are free to experiment and design anyway you want, just make sure that the color scheme and font-scheme is consistent with the new BRL-CAD web design.
