=== Fix bounding box function for our polygonal mesh (BoT) primitive ===
  
{| style="background-color:#fefefe; border-style: solid; border-width: 4px;" width="100%"
+
BRL-CAD provides functions for its geometric primitives that define a bounding box - a box that completely encloses the volume described by the primitive.  Ideally, these boxes are as small as possible while still enclosing the primitive.  Currently the routine for BoTs is incorrect.  You can use stl-g, obj-g, or any of our other *-g converters to import BoT geometry for testing.

=== Close MGED only when both windows are closed ===
 
  
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 run, it creates 2 windows: a text console for commands and an interactive graphics windowCurrently, if you close the graphics window, it quits the application.
+
This task involves studying the current code for the function rt_bot_bbox() and determining what is causing the current inaccuracies (the mged 'bb' command is a good way to visualize primitive bounding boxes). Make changes to produce a more optimal bounding boxReimplement it from scratch if you like.  The raytracing prep code in rt_bot_prep does prepare a better bounding box, so that is one place to check.
 
 
This task involves change behavior so that MGED exits only after closing ''both'' windows.  Closing just the graphics window  or text console should not quit MGED.

{| style="background-color:#fefefe; border-style: solid; border-width: 4px;" width="100%"
+
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 run, it creates 2 windows: a text-console command window and an interactive graphics window.  When the user closes one of those windows, there is a bug.  Closing the graphics window closes the command window.

=== Implement a primitive centroid function ===
 
  
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 '''ell'''ipsoid.  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 more tricky to compute.
+
This task involves fixing this behavior so that ONLY closing ''both'' windows terminates the process properly and that closing either window does not take the other along with it.
  
This task involves writing a new callback function that takes an rt_db_internal object and calculates its centroid (as a point_t 3D point). There are numerous examples in our code where we compute centroids for other primitives.  The primitives that do not already have a centroid callback are itemized in following.

This task involves implementing a UV-mapping callback for any of the primitives that do not already have a functional UV-callback defined.  Note that this is an advanced task that might take you more than a couple hours if you don't have solid coding skills, but it's ultimately just a few lines of code.  See other primitives that already implement a UV-mapping callback for reference.

=== Fix elliptical torus triangulation ===
 
 
BRL-CAD has many 3D object types, one of them being an "Elliptical Torus".  If you create a new MGED database and run this sequence of commands, it'll crash due to excessive recursion:
 
 
<pre>
 
make eto eto
 
tol norm 1
 
facetize eto.bot eto
 
</pre>
 
 
This task's goal is to reproduce, identify, and fix the bug so that detailed eto tessellation completes successfully.  To get started, see the rt_eto_tess() function in src/librt/primitives/eto/eto.c and the facetize command logic in libged.
 
 
Code:
 
* src/librt/primitives/eto/eto.c, <- you'll probably need to modify this file
 
* src/libged/facetize/facetize.cpp

=== Implement a function that evaluates volume with spherical sampling ===
 
 
Implement this function:
 
 
    int estimate_volume(struct db_i *dbip,
 
                        struct directory *dp,
 
                        size_t min_samples,
 
                        double confidence);
 
 
For this function, you'll want to read up on some of BRL-CAD's basic data structures by looking at headers in the include/rt directory or by reading our [https://brlcad.org/docs/api/ API documentation].  Calling rt_db_internal() and rt_bound_internal() will get you the bounding box around geometry from which you can calculate a bounding sphere.  Once you have the bounding sphere, randomly generate a set of min_samples*2 points on the surface of the sphere.  Shoot a ray through those points using rt_shootray(), as in the ray tracing [[Example_Application|example]].  Keep track of a volume estimate and keep shooting sets of min_samples rays until the estimate is less than the specified confidence value.  Volume of a sphere is (4/3 * pi * r^3) so dividing that by num_samples will give a per-ray factor and multiplying all hit thicknesses by that factor will give a running volume estimate.

=== Implement a platform independent re-entrant sort function ===
  
{| style="background-color:#fefefe; border-style: solid; border-width: 4px;" width="100%"
+
The classic C library qsort() does not support a context parameter.  A work around is to store the context information in a static variable.  However, this solution is not thread save and may result in unpredictable behavior.
| style="padding: 20px;" |
 
  
=== Implement a function to return an object's color ===
+
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.
  
CAD geometry can have colors specified in a number of ways including directly on that object, in a parent object, and in a lookup table.  For this task, you're going to implement a function that reports the color of an object given a path to that object:
+
Code:
 
+
* src/libbu/sort.c
    int get_color(struct db_i *dbip, const char *path, struct bu_color *rgb);
 
 
 
You'll need to iteratively consider each object named on the specified path (e.g., "/car/wheel/tire.r/torus") starting with "car" and working your down the path (i.e., 'wheel', 'tire.r', and then 'torus') to 1) see if a color is set on that object and 2) see if that color overrides lower-level colors (i.e., is inherited down the path), and 3) if it's a region object, whether there is a color set in the region table.  You'll need to db_lookup() each object on the path to get access to its data.
 
 
 
For this function, you'll want to read up on some of BRL-CAD's basic data structures by looking at headers in the include/rt directory or by reading our [https://brlcad.org/docs/api/ API documentation].  This task may seem complicated if you're not familiar with C/C++ APIs, data structures, or hierarchical paths, so don't be shy [https://brlcad.zulipchat.com asking] questions.

void bu_sort(genptr_t array, size_t nummemb, size_t sizememb, int (*compare)(const_genptr_t, const_genptr_t, genptr_t), genptr_t context);

=== Stub in an OpenVDB object ===
 
 
 
BRL-CAD has dozens of distinct primitive object types.  For this task, you're going to implement the bare minimum to necessary to create a new object with the "make" command in MGED.
 
 
 
The best way to achieve this task is by searching for a keyword for another primitive (e.g., 'grep -r -i superell .') and implementing your new object the same way.  Start with the 'make' command itself in src/libged/make/make.c and add "vdb" alongside where you find one of the other primitive types (e.g., superell).  To get that to compile, you'll have to add new symbols you've defined into header files (e.g., include/rt/rtgeom.h).  You'll eventually need to implement barebones logic in src/librt/primitives/vdb too.
 
 
 
Code:
 
* include/rt/defines.h <- needs an ID
 
* include/rt/geom.h <- needs an "internal" i.e., in-memory structure
 
* src/libged/make/make.c <- needs to recognize "vdb" as a valid type
 
* src/librt/primitives/table.cpp <- needs an entry
 
* src/librt/primtiives/vdb <- needs a dir
 
* src/librt/primitives/vdb/vdb.c <- needs _import5/_export5 callbacks, maybe _describe too

=== Write an article "BRL-CAD for dummies" ===
  
{| style="background-color:#fefefe; border-style: solid; border-width: 4px;" width="100%"
+
Although BRL-CAD has extensive documentation, still it needs a short and simple document which is particularly built for dummies.
| style="padding: 20px;" |
 
=== Complete our "Intro to BRL-CAD Modeling" tutorial and extend it ===
 
  
We've developed two short and simple tutorials for introducing new users to modeling with BRL-CAD.
+
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 doing one of the tutorials (they take about an hour) and then extending it with a new section or making some other improvement. At the end of the tutorial are several optional advanced "exercise left to the reader", for example.  Write a half-page step-by-step for one of the exercises left to the reader. Include screenshots and images to make it look nice so the reader is not bored.
+
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 up Wiki page tutorial on our Volumetric Primitive ===
 +
 +
BRL-CAD provides a couple dozen distinct primitives.  Each primitive is defined by a set of parameters.  Several of the more complex primitives have a wiki page describing them in more detail with an example on how to create them.
 +
 +
This task involves writing up a page on the VOL primitive.  Figure out how to use it (see the "in" command), create an example input data set, and write up a wiki page on exactly what steps are needed similar to our other wiki pages:
 +
 +
References:

=== 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.

=== Write an article soliciting a Windows platform maintainer ===
 +
 +
BRL-CAD runs on a number of platforms and distributes releases many times a year.  Creating 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 Windows.  Basically, it's a volunteer job, it's a lot of work, but not very hard and very rewarding.  There are thousands of binary downloads every month, so lots of people benefit from a maintainer's efforts. 
 +
 +
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 responsibility.  Come talk to us on IRC for more specific details.

=== Model BRL-CAD logo in BRL-CAD ===
  
==Outreach and Research ==
+
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..
''Tasks related to community management, outreach/marketing, studying problems, and recommending solutions''
+
 
 +
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.

=== Create prototype 2D Drawing ===
  
{| style="background-color:#fefefe; border-style: solid; border-width: 4px;" width="100%"
+
BRL-CAD provides limited services for drafting features including the production of 2D CAD drawings (blueprints).
| style="padding: 20px;" |
 
=== Upgrade OpenNURBS, report issues ===
 
  
BRL-CAD uses a customized OpenNURBS library for advanced geometry but it's out of date.  For this task, you're going to download the latest OpenNURBS code and upgrade the sources we bundle.  The easiest way is probably to move src/other/openNURBS to src/other/openNURBS.backup, and then put the latest OpenNURBS release into src/other/openNURBS.
+
This task involves designing a 2D CAD drawing prototype.  The prototype MUST capture a set of design requirements and follows industry conventions.
  
Once that's done, you'll need to add the src/other/openNURBS.backup/CMakeLists.txt file and make sure the list of files it has matches the files in src/other/openNURBS.  Last but not least, re-run cmake and make sure it compiles. You may need to consult the newer openNURBS makefile to see if there are other edits needed in the CMakeLists.txt file.
+
If you've never seen a real blueprint drawing before, then this task might be too hard for you.  Your result needs to refer to ISO 128 and/or ASME Y14.41 or other standard drawing elements.  
  
Save output from any commands you run because you'll probably encounter an error, and that's okay.  Just submit logs of all output so we can figure out next steps.
+
Basically, identifying a style of drawing that we should support including pointing out the critical elements to be included on each drawing, their location, size, placement, etc.

This task involves modeling a toy car in BRL-CAD. The toy car should be modeled in such a way that it can be printed using a 3d printer. The shape of toy car should be thought by keeping the word TOY in mind. As this shape would be 3d printed, all the axle and wheel arrangement should be done.
 +
 +
The output of this task would be a rendered image, and .g file of the toy car. If you wish to write a step by step tutorial of creating this model, search for it as another GCI task is there to write a tutorial.

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.  Note you may have to go through some or the MGED tutorials (see Docs on our website).

=== Categorize all of BRL-CAD's commands into a spreadsheet ===
 +
 +
BRL-CAD is a suite of more than 400 processing tools, image tools, geometry converters, and more. There is an existing spreadsheet that characterizes all of the available commands in terms of inputs, outputs, and options, but there is insufficient characterization of BRL-CAD's commands as to how they logically group and work together.
 +
 +
This task involves building up a spreadsheet that lists all of our commands, describing a finite set of command categories, and characterizing all commands into those categories while filling in the spreadsheet with details for each command.
 +
 +

 +
* A spreadsheet template will be provided.

===  Design a Cover Photo for Facebook page (and other social networks) ===
  
{| style="background-color:#fefefe; border-style: solid; border-width: 4px;" width="100%"
+
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.

=== Categorize commands into a spreadsheet ===

It should be consistent with the color scheme of our new website design.
  
BRL-CAD is a suite of more than 400 commands, processing tools, image tools, geometry converters, and more.  MGED also has a command-line with hundreds of commands too.  Help us reorganize one of those command sets.

===  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.

=== Creating Motion Typography video for BRL-CAD  ===
  
{| style="background-color:#fefefe; border-style: solid; border-width: 4px;" width="100%"
+
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.
| style="padding: 20px;" |
 
  
===  Design a Cover Photo for Facebook (and other social media) ===
+
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.
  
BRL-CAD website and marketing materials are constantly undergoing change.  Effective marketing requires well designed and attractive imagery. Imagery ideally should showcase some feature of BRL-CAD, some highlight, something visually interesting and compelling.
+

=== Create a screen-cast for BRL-CAD  ===
 +
 +
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.
 +
 +
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.

=== Loading Google charts from API  ===
  
{| style="background-color:#fefefe; border-style: solid; border-width: 4px;" width="100%"

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.

=== Create a video for BRL-CAD  ===
 
  
Watching someone else use software is incredibly helpful to some. Create a screen-cast video for BRL-CAD that showcases some  feature, goes over steps involved in creating some model, or shows how to accomplish some other task.
+
Reference:
 +
*https://developers.google.com/chart/interactive/docs/index
  
You'll need to install BRL-CAD on your computer and use it in the video.  Create or import some model and make a recording.
