05:25.28milindaWhen I create a DM_TYPE_NULL or DM_TYPE_TXT the display manager window creation is successful.  But I can't create DM_TYPE_X or DM_TYPE_QT.
05:26.49milindaI think the problem is the preprocessor directives. What are the files that I need to include in order to satisfy the preprocessor dependencies for DM_TYPE_X or DM_TYPE_QT window creation?
05:27.33milindaSean Can you please answer to these questions :)
05:28.13milindaWhat are these DM types? Where is the documentation for these DM types ?
05:29.50milinda@Sean Once you have executed dm_open method successfully how can you create a dm window with a visible dm ? I mean how to view/show the dm that we have opened/created ?

15:05.34starseek1rsofat_: I got it
15:06.11starseek1ralthough, for the record, the compiler told you what was going on: variable ns set but not used
15:06.22starseek1rso you get rid of variable ns, and clear the warning
15:06.38sofat_Hmm?
15:06.43starseek1rfixing build error
15:06.57starseek1ryou had asked earlier
15:08.14sofat_This is fresh code i just download and compile so i don't  know how i solve this . this is not my fault
15:08.55starseekersofat_: understood. but it's still a learning opportunity
15:09.20sofat_Okay i will try to solve this
15:09.30starseekerI already did
15:09.35starseekerr65208
15:09.57starseekerso just do an update again and it should go away
15:12.14starseekersofat_: if you run into another situation like that where the latest BRL-CAD doesn't build, you can always back up your local checkout to an earlier revision that does work
15:12.42starseekersomething like: svn update -r62000
15:13.20starseekerthe reason I was explaining the compiler message was you had asked how to "solve the error"
15:13.50starseekerif you just want to "avoid the error" instead for web development you can back up to a revision you know to work until someone fixes the main build

18:33.59starseekersofat: you're trying to commit to the main svn repo?
18:34.23starseekerthat sounds like a problem on the sourceforge side, if that's the case...
18:34.43starseekermilinda: apologies, trying to juggle multiple things
18:35.17sofatok i have another code of this so i try on that to create the patch file in correct manner.
18:35.22milindaThat's okay thank you very much for replying. :)
18:35.33milindaSo Can you please answer my questions
18:36.16milinda@Starseeker I want to create a dm window in qt
18:36.22starseekermilinda: since the non-graphical ones are successful, it sounds like some sort of context initialization
18:37.12starseekermilinda: I see brlcad replied on the mailing list
18:37.23starseekermilinda: this is the step file viewer, correct?
18:37.30milindayes
18:37.44starseekeryou're planning to use Qt?
18:37.49milindayes
18:38.19starseekermy own suggestion would be to just go with their OpenGL widget, rather than use libdm
18:38.20milindaSo I should create the DM_TYPE_QT one right?
18:38.32starseekerwell... there are issues
18:38.36milindaokay I thought of that
18:38.46starseekerthe DM_TYPE_QT dm is still relatively experimental
18:38.54milindaI also figured out that libdm is so buggy.
18:38.57starseekerand can't do shaded displays
18:39.20starseekermilinda: it's not so much buggy (although it does have bugs) as challenging to use
18:39.48milindaokay so is it okay I use something out of brlcad?
18:40.06starseekerI'll reply to brlcad on the mailing list, but my suggestion would be to experiment with plain Qt OpenGL initially
18:40.43starseekerif you're already relying on Qt to begin with, and you don't need libdm's extras, I'd start with Qt's OpenGL to get something up and running
18:40.59milindaOkay thank you very much I am stuck at this point for more than a week now :)
18:41.49starseekerI'll respond on the list, so follow that discussion
18:42.01starseekerbrlcad may have a different take
18:42.34milindaokay brlcad is the one who told me to create a libdm window :)
18:42.40starseekerwinces
18:42.53starseekeralright.  Keep an eye on the list discussion
18:43.11milindaI also think OpenGL implementation is good simple and clean implementation.
18:43.37milindaDoes libdm contains all the functionality to visualize CAD geometry files ?
18:44.01starseekermilinda: in principle libdm may add extra flexibility, but it's a mean way to start - Qt should give you a basic OpenGL window virtually "for free", and my take would be we can introduce libdm later at need
18:44.31starseekernot really - libdm is something of a "wrapper" across various drawing layers
18:45.17starseekeronly the OpenGL based ones can do "shaded display" (what most people will think of when they think 3D drawing) but the X and Qt backends can provide wireframe based visuals
18:46.56milindaWhat you meant by "various  drawing layers " ? Is it various drawing libraries ?
18:49.14starseekerright - OpenGL, raw X, the Qt drawing layer, Tk canvas, etc.
18:55.10milindaso libdm contains OpenGL?
18:59.25starseekerit interfaces to OpenGL
19:00.06starseekerthere are two main layers for talking to OpenGL - the "ogl" interface which is X11 specific and needs GLX, and "wgl" which is specific to Windows
19:00.36starseekerthere's a newer one that targets OpenSceneGraph as a backend - "osgl" - but that's still experimental
19:01.17starseekerthe Qt backend is attempting (if I recall correctly) to use the Qt drawing canvas directly, without reference to OpenGL
19:01.47starseekerwhich means we need to do shaded 3d display drawing ourselves in that backend (that will be slower than OpenGL)
19:02.14starseekerit's a good fallback if OpenGL *isn't* available for some reason, but it's still a fallback
19:07.12milindaThis stepviewer has nothing to BRLCAD code right ? The requirement is to develop a simple light weight STEP Viewer which can visualize step files  right ?
19:07.31milindaAnd it should be standalone application

19:15.34Shubhambrlcad: I really wanted to talk about the editing rights on the github repository for OGV-meteor
19:20.26starseekermilinda: that's my understanding, but you'll need some ability to triangulate NURBS surfaces if you want to view them (STEP uses NURBS for its basic geometry representation)
19:20.53starseekermilinda: that means you'll need our ability to generate triangles that represent NURBS surfaces
19:21.02starseeker(and hence our libraries)
19:21.12starseekerbut libdm doesn't encode that logic
19:21.16starseekerthat's librt and lower
19:23.15sofatstarseeker, i am submit my new patch on wordpress xsl style sheet please accept this as soon as possible. patch ticket number 374.
19:23.27Notify03BRL-CAD:starseeker * 65211 (brlcad/trunk/include/bu/opt.h brlcad/trunk/src/conv/gcv/gcv.cpp and 3 others): Eliminate the bu_opt_desc index parameter. Instead, base a help generation decision about whether two different desc lines are aliases on whether or not they are impacting the same set_var pointer.
19:24.47milindaSo what you are saying is we can OpenGL window to handle the graphics part. we need brlcad libraries to triangulate NURBS surfaces right ?

19:59.51milindaokay thank you very much for your guidance @starseeker. Really appreciate your help.
20:00.45milindaI will go with OpenGL window creation. If @brlcad has some different idea we can resolve it later. :)
