06:59.03BulletCatcherts: The "news" table in ts-CMS_structure.sql does not have a "title" column.
06:59.08BulletCatcherThis conflicts with the SELECT statements near line 237 of web/CMS/add-ons/newsSystem/newsSystem.php .
06:59.11BulletCatcherI suspect the column should be added to the table.

15:59.33JeffMseems the spamers are the major users of the forums these days
16:02.50spldartTiz a pity
16:03.56BulletCatcherAt least they haven't infiltrated the game.
16:04.08BulletCatcher(That spammer is now gone from the forum.)
16:04.49JeffMI wonder if more people hit the forums in a day then hit the game?
16:05.47spldartHrmph... I was just playing when I came back to this channel.. Only hit the board just now because of your spammer board attendance comment...
16:05.55JeffMheh
16:06.16spldartHrm... looking at these dates it would almost look like I was bringing up old posts just to replay to any of the most 'recent'
16:06.17spldartwow
16:11.13blast007spldart: yeah, pretty much ;)
16:14.27KTLi'm trying to use cgal to merge 3d solids together, it's not going well :(
16:16.19JeffMuse parasolid
16:16.43KTLc++ lib?
16:23.07*** join/#bzflag I_Died_Once (~I_Died_On@unaffiliated/idiedonce/x-1828535)
16:26.15JeffMtechincaly
16:26.24JeffMbut you would not want to use it feasably
16:26.29JeffMit's comercial
16:27.05KTLso there are only 2 "open source" options: opencascade or cgal
16:27.28KTLand opencascade consists of 1000s of headers without accessible documentation
16:27.57JeffMahh they just did the doxygen stuff?
16:28.53KTLsearches

16:29.56*** join/#bzflag temporalD (~a_temp_di@bzflag/serverop/TemporalDistraction)
16:30.03KTLthat should exist, for windows
16:31.04JeffMyeah I know it exists, it just generates crappy docs from headers. but many projects use it
16:31.43KTLargh to get even that you need to register
16:31.56JeffMsolid modeling kernels are big biz
16:32.10KTLwhile it's old allready
16:32.11JeffMyou could use code from brlcad
16:32.16KTLuh ?
16:32.23JeffMthe product not the person
16:32.32KTLaa :)
16:32.37JeffMbrlcad is an open source CAD system
16:32.48JeffMit has some home grown solids stuff
16:33.28*** join/#bzflag kierra (c9cb621e@gateway/web/freenode/ip.201.203.98.30)
16:33.29KTLno debian package, but freeeee
16:33.44JeffMit's very specalized but yes it is open source
16:35.11KTLdownloading deb package, curious about the contents
16:39.16JeffMwhat are you trying to do? something specific or make a lib that does something?
16:39.27KTLo you will find it funny
16:39.30JeffMcus if you just need 2 solids added or subtracted, I can do that here
16:39.45KTLfusing bzflag boxes and pyramids automatically :D
16:39.53JeffMahh
16:40.27KTLbut in general, i want tricks like that in my arsenal
16:40.41JeffMyeah then you need a kernel
16:40.45*** part/#bzflag kierra (c9cb621e@gateway/web/freenode/ip.201.203.98.30)
16:40.47JeffMand a solid representation
16:40.50JeffMnot just a mesh
16:41.03JeffMwhen doing CSG you want analitics as much as possible
16:41.16JeffMmeshes get wonkey fast when you do a lot of operations on them
16:41.35JeffMlots of split faces and the like
16:42.13KTLhttp://www.cgal.org/Manual/3.3/doc_html/cgal_manual/Nef_3/Chapter_main.html  <- i try to get results out of this but ... getting sensible results proofs difficult
16:44.02KTLslow to compile, slow to run, complains easily (asserts everywhere), ... and the results are ... still incomprehensible to me
16:47.17JeffMyeah there is a lot of math and concept stuff you should learn before doing general solid modeling
16:47.28JeffMit's more then just "adding meshes"
16:47.43JeffMsolids are defined by math functions and surfaces, not just a list of triangles
16:48.16KTLwell, in cad-software it's fairly easy, what i want to do is the automated equivalent of saying "box here, another box here! press the 'union'-button"
16:48.18JeffMyou may want to also look at the code used in the quake 1 and 2 engine for it's bsp based stuff
16:48.23JeffMthey added mesh brushes together
16:48.37*** join/#bzflag bier|tp (~bier@p54A5BFA4.dip.t-dialin.net)
16:48.37JeffMyeah but what that button does is very complex ;)
16:48.48KTLwell a library is supposed to do the complex stuff
16:48.48JeffMcus it works on more then just boxes
16:49.08KTLmy code should call the lib not reimplement it
16:49.10JeffMthere is little good software in the field of open source CAD/CAM
16:49.24JeffMthere isn't a big call for it
16:49.34*** join/#bzflag bier (~bier@p54A5BFA4.dip.t-dialin.net)
16:49.42JeffMand a lot of money to be made with it, so few people write it "for the fun"
16:50.20JeffMis making some of that money right now
16:50.35KTLmmm...
16:51.30KTLmaybe i could use call the mged command from brlcad ...
17:00.15JeffMyou'd have to put your stuff in there body format
17:00.35JeffMare you just trying to get the UV coordinates to line up so it dosn't look like crap?
17:01.50KTLi want the edge lines after the union, i might want to plaster my fractals over the objects eventually, i want to get the minimal amount of faces , euh well stuff like that
17:01.58JeffMahh
17:02.09KTL(and automated)
17:14.01KTLhttp://www.openscad.org/  <- thizzzz might be intrezztinggg
17:15.14KTLis using the Qt4, the OpenCSG library and the CGAL library.
17:15.27KTLthe joy is rising
