== Test-Driven Development for BRL-CAD NURBS/Brep Boolean Operation ==<br />
* '''Description''': Currently, BRL-CAD has implemented a series of NURBS and Brep operations, and in some cases it works well. But there are many cases to be tested, improved or solved like missing surfaces or solids and optimizing topology of Brep. This project works in Test-Driven Development(TDD), aims to test and develop NURBS/Brep part of BRL-CAD, to ensure correctness of geometry and topology in common and special cases.<br />

* '''26 May''': Created workspace where I build brlcad and rt-cubed. Set path for Qt 5.14.2 so that arbalest could be run to check if it is running without errors.</div>LordOfBikeshttps://brlcad.org/w/index.php?title=User:H1manshu/GSoC2022/Abstract&diff=12145User:H1manshu/GSoC2022/Abstract2022-05-27T08:49:48Z<p>LordOfBikes: created from User:H1manshu/GSoC22/Abstract</p>

<div>==Abstract for New BRL-CAD GUI==<br />
* The project aims to add more CAD features and improvements to arbalest. <br />
* Arbalest will be an improvement over existing editors MGED and Archer since they are old GUIs developed during the 80s and 90s which lack modern GUI features and are not so user-friendly compared to Arbalest which is a modern Qt-based UI.<br />
*This project will borrow geometry management services from BRL-CAD’s core C++ interface which is a self-contained object-oriented interface and also from LIBGED which is basically all commands available to both MGED and Archer.</div>LordOfBikeshttps://brlcad.org/w/index.php?title=Google_Summer_of_Code/2022&diff=12144Google Summer of Code/20222022-05-27T08:43:56Z<p>LordOfBikes: set LibreCAD project links</p>

Since 2005, Google has run an awesome open source software development program specifically for ''students'' called the [http://code.google.com/soc/ Google Summer of Code] (GSoC). Under this program, Google funds students to write code for open source projects during the northern hemisphere's summer timeframe:<br />
<br />
* The student writes a project proposal for BRL-CAD.<br />
**Sometimes their project idea caters to something that the open source organization suggests and sometimes it's an idea entirely of the student's conception.<br />
* Proposals are reviewed, evaluated, and ranked by the open source organization's mentors.<br />
* Google allocates a certain number of slots to each participating organization<br />
** That, in turn, determines how many student developers work with that organization.<br />
<br />
=Getting Started [[Summer_of_Code/Checklist|Checklist]]=<br />
<br />
Whether you're applying or accepted, we've itemized everything you need to do into a simple '''[[Summer_of_Code/Checklist|CHECKLIST]]'''. We're here to help you become new open source developers, so don't be shy if you have any questions.<br />
<br />
== The Selection Process ==<br />
<br />
GSoC is about getting people involved and contributing to open source over the long-term. As such, we heavily weight our application selection process towards students that are interested in remaining involved in BRL-CAD and open source software development long after GSoC has ended. <br />
<br />
'''''GSoC is not a job.''''' If you think this is just a summer job, then GSoC is probably not for you. It's only like a job in terms of planning your time commitment over the summer.<br />
<br />
Additionally, submissions are graded based on perception of the submitter's abilities to complete the task within the program timeframe, general consensus on the technical approach being proposed, and overall interest in having such modifications made to BRL-CAD. Particular notice is made of students that are responsive to questions and readily interactive in the IRC channel or on the mailing list. Communication is a great thing.<br />
<br />
Just about every GSoC organization receives considerably more project proposals than can be accepted. Every application gets read multiple times and reviewed in detail. Of those applications, only a small subset are selected so keep in mind that the selection process is rather competitive and difficult. <br />
<br />
Whether or not you are accepted, contributing to open source outside of GSoC is one of the main goals of the program and is the best way to be noticed and get your proposal accepted. Keep that in mind. Thanks for your interest and we look forward to working with new BRL-CAD developers!<br />
<br />

<br />
You can check out promotional flyers that have been prepared in the past on our [[Google_Summer_of_Code/Flyers|GSoC flyers]] page.<br />
<br />
==[[Google_Summer_of_Code/2022|GSoC 2022]]==<br />
<br />
Our umbrella selected 7 students that prepared proposals for IfcOpenShell, BRL-CAD, KiCad, LibreCAD and OpenSCAD.<br />
<br />
==[[Google_Summer_of_Code/2021|GSoC 2021]]==<br />
<br />
With global turmoil in full effect, we again reigned back participation, only accepting 6 students, all of which were successful. Students worked with IfcOpenShell, FreeCAD, OpenSCAD, and BRL-CAD.<br />
<br />
==[[Google_Summer_of_Code/2020|GSoC 2020]]==<br />
<br />
We reigned participation back a bit in 2019, accepting 8 students, all of which were successful. Students worked with FreeCAD, BRL-CAD, OpenSCAD, and LibreCAD.<br />
<br />
==[[Google_Summer_of_Code/2019|GSoC 2019]]==<br />
<br />
Our umbrella selected 10 students that prepared proposals for BRL-CAD, OpenSCAD, LibreCAD, FreeCAD, and Slic3r. students passed successfully.<br />
<br />
==[[Google_Summer_of_Code/2018|GSoC 2018]]==<br />
<br />
Our umbrella selected 9 students that prepared quality proposals for BRL-CAD, FreeCAD, LibreCAD, and Slic3r. By the end of GSoC, all but 1 passed successfully.<br />
<br />
==[[Google_Summer_of_Code/2017|GSoC 2017]]==<br />
<br />
Our umbrella accepted 10 students that prepared quality proposals and demonstrated commitment. Students were selected for LibreCAD, Slic3r, BRL-CAD, and FreeCAD.<br />
<br />
==[[Google_Summer_of_Code/2016|GSoC 2016]]==<br />
<br />
This year we tamed it back to 9 students working on projects for BRL-CAD, OpenSCAD, LibreCAD, and FreeCAD (new partner). We were not going to apply at all, but we also didn't want to lose momentum with our umbrella partners or leave them to fend for themselves.<br />
<br />
==[[Google_Summer_of_Code/2015|GSoC 2015]]==<br />
<br />
This year we had a whopping 12 students accepted to work on projects. As an umbrella organization, we expanded our cooperation to include LinuxCNC.<br />
<br />
==[[Google_Summer_of_Code/2014|GSoC 2014]]==<br />
<br />
Hoping to foster collaboration and communication, we actively reached out to a number of related and active open source CAD communities. We expanded our umbrella to include cooperation with STEPcode, LibreCAD, and OpenSCAD.<br />
<br />
==[[Google_Summer_of_Code/2013|GSoC 2013]]==<br />
<br />
Middle ground, not too many, not too few. It was just right. We accepted seven students that all participated successfully. This was also our first year participating as an umbrella organization, coordinating one of those slots with the STEPcode community.<br />
<br />
==[[Google_Summer_of_Code/2012|GSoC 2012]]==<br />
<br />
This year, we aimed big. Lots of mentors, lots of students. Compared to some of the larger notable orgs, students had a really great chance of acceptance if they were actively communicative and highly passionate about their project idea and BRL-CAD. Overall, we accepted eleven students.<br />
<br />
==[[Google_Summer_of_Code/2011|GSoC 2011]]==<br />
<br />
{|align="right"<br />
|[[Image:BRL-CAD_GSoC2011_flyer.png|thumb|left|165px]]<br />
|}<br />
<br />
After a year off focusing on a major development initiative, BRL-CAD once again was accepted to participate in the Google Summer of Code. We structured our participation minimally, however, intending to only accept a couple students. In the end, we only accepted two students, both of whom did outstanding work.<br />
<br />
==GSoC 2010==<br />
<br />
We [http://brlcad.org/d/node/47 took a break] and didn't apply to participate in 2010. We wanted to give another org the chance to participate and allow ourselves a little extra time to focus on our own development priorities.<br />
<br />
<br />
==[[Google_Summer_of_Code/2009|GSoC 2009]]==<br />
<br />
{|align="right"<br />
|[[Image:brlcad_gsoc2009_flyer.png|thumb|left|128px]]<br />
|}<br />
<br />
For the second year in a row, BRL-CAD is participating in the Google Summer of Code. BRL-CAD was accepted as a participating organization and took upon five students, four of which successfully worked their projects and integrated with the development team.<br />
<br />
<br />
==[[Google_Summer_of_Code/2008|GSoC 2008]]==<br />
<br />
{|align="right"<br />
|[[Image:brlcad_gsoc2008_flyer.jpg|thumb|left|128px]]<br />

<br />
The Google Summer of Code 2008 was announced on February 25, 2008. BRL-CAD was accepted as a participating organization and took upon four students, all of which successfully worked their projects and integrated with the development team.<br />

<br />
Well prepared proposals from capable students have an ''outstanding'' chance of getting selected. We consider proposals for all skill levels ranging from simple to crazy hard and everything in between. [https://lists.sourceforge.net/lists/listinfo/brlcad-devel Introduce yourself], and we'll help you plan one right for you.<br />
<br />
Remember that project descriptions are just ''initial ideas''. You must expand with [[Summer_of_Code/Application_Guidelines|considerably more detail]]. Change the goals to fit your experience and interests. See our '''[[Summer_of_Code/Checklist|checklist]]''' to get started.<br />
<br />
This year, BRL-CAD is coordinating with five other communities that will get 1-2 students each to help bridge our work and encourage collaboration. Projects that help exchange data or share code are desired!<br />

Well prepared proposals from capable students have an ''outstanding'' chance of getting selected. We consider proposals for all skill levels ranging from simple to crazy hard and everything in between. [https://lists.sourceforge.net/lists/listinfo/brlcad-devel Introduce yourself], and we'll help you plan one right for you.<br />
<br />
Remember that project descriptions are just ''initial ideas''. You must expand with [[Summer_of_Code/Application_Guidelines|considerably more detail]]. Change the goals to fit your experience and interests. See our '''[[Summer_of_Code/Checklist|checklist]]''' to get started.<br />
<br />
This year, BRL-CAD is coordinating with five other communities that will get 1-2 students each to help bridge our work and encourage collaboration. Projects that help exchange data or share code are desired!<br />

<br />
Well prepared proposals from capable students have an ''outstanding'' chance of getting selected. We consider proposals for all skill levels ranging from simple to crazy hard and everything in between. [https://lists.sourceforge.net/lists/listinfo/brlcad-devel Introduce yourself], and we'll help you plan one right for you.<br />
<br />
Remember that project descriptions are just ''initial ideas''. You must expand with [[Summer_of_Code/Application_Guidelines|considerably more detail]]. Change the goals to fit your experience and interests. See our '''[[Summer_of_Code/Checklist|checklist]]''' to get started.<br />
<br />
This year, BRL-CAD is coordinating with five other communities that will get 1-2 students each to help bridge our work and encourage collaboration. Projects that help exchange data or share code are desired!<br />

<br />
Well prepared proposals from capable students have an ''outstanding'' chance of getting selected. We consider proposals for all skill levels ranging from simple to crazy hard and everything in between. [https://lists.sourceforge.net/lists/listinfo/brlcad-devel Introduce yourself], and we'll help you plan one right for you.<br />
<br />
Remember that project descriptions are just ''initial ideas''. You must expand with [[Summer_of_Code/Application_Guidelines|considerably more detail]]. Change the goals to fit your experience and interests. See our '''[[Summer_of_Code/Checklist|checklist]]''' to get started.<br />
<br />
This year, BRL-CAD is coordinating with five other communities that will get 1-2 students each to help bridge our work and encourage collaboration. Projects that help exchange data or share code are desired!<br />

Some kinds of taps and materials benefit from "peck tapping", where the tap is backed out from the work piece periodically. Peck tapping currently has to be done "by hand", by programming one G33.1 move for each peck. This task is to add support for a "peck depth" parameter to the G33.1 command, analogous to peck drilling in [http://linuxcnc.org/docs/html/gcode/gcode.html#sec:G83-Drilling-Peck G83].<br />
