I would like to participate in GSoC program, what is the right way to start?
As you're probably now aware of, we're not going to be participating in GSoC this year. Maybe next year. We may still hold our own program at some point in the future as well, keep an eye out on our news mailing list. Should you be interested in getting invovled with development of BRL-CAD regardless, feel free to stop by our IRC channel (#brlcad on irc.freenode.net).
