BRL-CAD
Media
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)! We operates as an umbrella organization with several CAx communities including: <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> We want to select at least one student for each, so feel free to ask us where to start. <a href="https://opencax.github.io"><img src="https://summerofcode.withgoogle.com/media/org/brl-cad/4ec07aqdfrvygfed-360.png"></a>
