14:58.41 starseeker Zhao_Anqing: it is expected (indeed, inevitable) that NMG changes will have impacts elsewhere
14:59.54 starseeker that's one of the aspects of that particular task - to make the necessary changes in the libraries that use NMG
15:02.23 Zhao_Anqing and now, I fix all the compile bugs in librt after removing nmgregion(but some place is just walkaround).
15:02.33 starseeker workaround?
15:03.04 starseeker Zhao_Anqing: that's a good first step, certainly
15:03.11 Zhao_Anqing yes, they are not fixed totally, I will check them again carefully.
15:03.41 Zhao_Anqing now just no compile errors in librt.
15:04.20 Zhao_Anqing then I will deal with the bugs in libged.
15:04.40 starseeker the real test will be whether functionality that uses NMG (the facetize command in MGED I belive has an option to use NMG, for examlpe) succeed
15:05.18 Zhao_Anqing OK, I get it.
15:05.59 Zhao_Anqing is it true that I should make sure everything goes with no problem before provide a patch?
15:07.02 starseeker you should be able to compile with strict flags (the default) and not introduce any functional regressions (make regress)
15:07.49 Zhao_Anqing Ok, thank you. I will remember it.
15:08.53 Zhao_Anqing by the way, I cannot find some docs in Wiki's document page about how to using NMG functions in MGED.
15:09.23 starseeker nmg functions aren't used directly - for the most part, they are lower level functions that are called by higher level commands
15:10.09 Zhao_Anqing but I see the NMG button in MGED....
15:10.14 starseeker for example, facetize -n sph.bot sph.s will take a sphere and create an NMG version of that sphere
15:10.41 starseeker ah. I believe that was an early attempt to add some support for NMG editing that was never finished
15:11.35 starseeker we have virtually no ability to directly edit NMG primtives - they are typically generated from other CSG primitives during conversion
15:12.43 starseeker support for editing NMG objects would be a "nice to have" but at this stage they primarily come into play during geometry conversions
15:14.43 starseeker it may prove necessary to add an "nmg" command similar to the "brep" command we have for NURBS, if serious debugging of NMGs proves to require graphical and data introspection
15:15.16 Zhao_Anqing OK..I see.
15:16.17 Zhao_Anqing So, anyway, I will continue to my bug fixing and test about removing the nmgregion.
15:16.22 starseeker sounds good
15:17.14 starseeker remember when posting to the IRC channel you want to post in #brlcad, and you may not always get a real-time response. We keep logs of the channel, and it is normal to get a delayed response to a question
15:18.03 Zhao_Anqing That's Ok, Thanks for your kind help and patient explain.
15:18.17 Zhao_Anqing ^-^
