Is precisely why I include brlcad(.org) on my FGLiveCD. ..modelling a solid, means you _do_ get its surfaces for free, even if you have to paint them. When it dries, it too becomes a solid. Modelling surfaces, means you _may_ get a solid for free, unless it leaks out some hole between your surfaces. ;o) -- ..med vennlig hilsen = with Kind Regards from Arnt... ;o) ...with a number of polar bear hunters in his ancestry... Scenarios always come in sets of three: best case, worst case, and just in case. _______________________________________________ Flightgear-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/flightgear-users
