22:16.06 siggraph ewilhelm: yes and no
22:17.12 siggraph a step converter (and everything related, which includes nurbs/brep, tessellation, and the actual step converter) are our #1 priority for the past and next 12 months (at least)
22:17.47 siggraph basically, it's still under development.. a ton of effort has been put into nurbs/brep to date (which is pretty much requisite for full/proper step support
22:21.17 MinuteElectron siggraph: How is LDAP going?
23:10.20 *** join/#brlcad Twingy (n=justin@74.92.144.217)
23:24.09 ewilhelm siggraph: thx. did narnia's work on the scl stuff get published?
23:24.58 ewilhelm I'm looking at doing some work with IFC, so I think I'm going to be building some kind of express schema support code
23:25.24 ewilhelm currently, the nist SCL code won't compile (and it looks like ./configure is a mess)
23:34.18 siggraph louipc: good info! thanks .. if you've still got gdb handy, I've got some other things you could check that would help -- and I presume that the patch didn't fix the problem by itself?
23:35.56 siggraph ewilhelm: narnia outright disappeared on me -- both he and I had fixed their build system (i.e. replaced it with a configure that actually works) but has not yet been integrated back into our repository because neither he or I got to a usable tool point
23:36.17 siggraph could have been on a branch, but like I said .. he disappeared on me, and he was unfamiliar with cvs
23:36.48 siggraph i could dig up what I have and commit it to a branch probably and get you access if you are interested in working on it
23:37.36 ewilhelm sure, or e-mail me a tarball even
23:39.04 ewilhelm looks like there was some other work at http://nwg.phy.bnl.gov/~bviren/uno/other/geant4.5.2-opt/source/geometry/solids/STEP/
23:39.35 ewilhelm though maybe that was a subset
23:40.56 siggraph what's your work, if I may ask?
23:41.14 ewilhelm http://scratchcomputing.com
23:41.38 ewilhelm you might remember me from 2-3 years back
23:41.50 siggraph oh, I remember exactly who you are :)
23:42.01 siggraph i mean specifically what are you doing with step/express
23:42.40 ewilhelm Industry Foundation Classes -- a Building Information Modeling exchange format
23:45.13 ewilhelm for architecture/engineering/construction data
23:45.13 siggraph so you're using step as your format? or express? or just importing/exporting step?
23:46.18 ewilhelm IFC is derived from STEP/express
23:47.14 siggraph derived as in a proper subset or an actual incompatible derivative?
23:47.15 ewilhelm or, I suppose the correct way to say it is "defined as an express schema"
23:47.21 siggraph ah, so same 'base language' but different schema
23:48.00 siggraph akin to sgml and xml
23:48.12 ewilhelm yeah, at least "as I currently understand it"
23:48.48 ewilhelm still getting my head bootstrapped into it
23:51.57 ewilhelm I guess 10303-11 is 'EXPRESS', which lets you define a schema (.exp file) which can then be referenced from a 10303-21 file with FILE_SCHEMA()
23:52.22 ewilhelm e.g. ISO-10303-21;
23:52.23 ewilhelm ...
23:52.28 ewilhelm FILE_SCHEMA(('IFC2X2_FINAL'));
23:56.19 ewilhelm IAI seems to be a little kinder about providing documents than ISO
23:58.11 siggraph ~IAI
