Just a note. There are more lines of code in the hit sanitizer for BOT than in the rest of the code proper. Don't believe me? Look at this: https://svn.code.sf.net/p/brlcad/code/brlcad/trunk/src/librt/primitives/bot/g_bot_include.c
rt_bot_makesegs_ is one of these sanitizers. On Tue, Oct 24, 2017 at 1:32 AM, Vasco Alexandre da Silva Costa <vasco.co...@gmail.com> wrote: > Ah nevermind.
