We plan on selecting 6-12 students to work on web projects, C/C++ projects, and more.  This year, BRL-CAD is coordinating with three other communities that will get 1-2 students each to help bridge our work and encourage collaborationProjects that help exchange data or share code are desired!

|width=62%|'''Port the GUI to C++:''' The GUI is currently coded in Perl using wxWidgets and our goal is to have it ported to C++. The wxWidgets API is almost identical between Perl and C++, so it's an easy task. There are a couple things where we use the dynamic features of Perl which are trickier and interesting to port.

Keep non-solid walls and slice them as single paths. Bonus: import SVG paths and position them freely using the GUI for printing as single extrusions.

This requires a fair amount of design work.
