  • BRL-CAD

    Media

    <p>This is the place to be if you love computer graphics. We do 2D/3D modeling, 3D printing, solid geometry, design, and more. Depending on the project, you have the opportunity to work with C/C++, Python, OpenGL, OpenCL, Qt, Javascript, and more... Help us develop open source computer-aided technologies (CAx)!</p> <br> <p>We operates as an umbrella organization with several CAx communities including:</p> <br> <ul> <li> - OpenSCAD is a solid 3D modeler with a rich syntax for programmable geometry. <li> - LibreCAD is a 2D modeling system specializing in blueprint-style drawings and draftings. <li> - IfcOpenShell is a library for working with standard IFC building model data. <li> - BRL-CAD is a solid modeling suite with conversion and advanced solid ray tracing features. <li> - Manifold is a solid geometry mesh processing library. </ul> <br> <p>We want to select at least one student for each, so feel free to ask us where to start.</p> <br> <a href="https://opencax.github.io"><img src="https://summerofcode.withgoogle.com/media/org/brl-cad/4ec07aqdfrvygfed-360.png"></a>

  • OpenAstronomy

    Science and medicine

    OpenAstronomy is a collaboration between open source astronomy, astrophysics & heliophysics projects that are used by researchers and software engineers around the world to study our universe either by analysing the data obtained from amazing instruments like the [James Webb Space telescope](https://jwst.nasa.gov/), the [Square Kilometer Array](https://www.skatelescope.org/) or the [Solar Dynamic Observatory](http://sdo.gsfc.nasa.gov/), developing very sophisticated numerical models (eg., [FLASH](http://flash.uchicago.edu/)) or designing interplanetary trajectories for human-made spacecraft. The analysis of such data helps multiple types of research, from being able to forecast solar storms to detecting planets in other stars, to understanding how galaxies are formed to explain the expansion and the origin of the universe.
