| 16:30.00 | brlcad | bhollister: do you have an example that builds a box? |
| 16:33.17 | vasc | hello sean |
| 16:33.48 | vasc | thanks for the positive evaluation. i would have liked things be even further ahead than they are though. |

| 17:05.00 | brlcad | vasc: you've been making decent progress, and at pretty much the rate I expected ... |
| 17:05.17 | brlcad | that's why I kept mentioning to just focus on one piece of this problem.. dragons everywhere |
| 17:09.43 | sofat | starseeker, I have submit the patch on menu file so please accept this patch. |

| 19:55.32 | ih8sum3r | s / so / some |
| 19:57.04 | brlcad | sofat: he's on vacation this week so I suspect he won't see your message for a while .. |
| 19:57.19 | brlcad | I can do better, stand by (sofat) |
| 19:57.21 | sofat | ok |
| 19:57.24 | sofat | no problem |
| 19:57.41 | brlcad | ih8sum3r: yes, let's go |
| 19:59.54 | brlcad | ih8sum3r: did you get through all the feedback items I gave you a couple weeks ago? |
| 20:00.04 | ih8sum3r | I think I'm almost done with the front end part except two things. In that two things, maybe there is a problem at the backend or something else, even shubham tried it. So shall I join shubham and complete the things at the back-end too. |
| 20:00.33 | ih8sum3r | Yes, except one i.e using default model image. |

| 20:03.54 | andrei_il | Hei, guys! I'm having some trouble with the CSG Importer that I'm working on and I would need your help. |
| 20:04.47 | andrei_il | I'm working on interpreting the rules proposed for the grammar and I'm using dom2dox as an example but I'm not sure if I'm understanding everything in there |
| 20:07.49 | andrei_il | For example , I don't understand what END_EXAMPLE; in the dom2dox_parser.lemon file does. If its a terminal, its not declared anywhere and I don't know what to understand from that |
| 20:11.15 | andrei_il | Also, the app_data_t structure was created to suit dom2dox parsing but I don't know how to modify it to work for csg |
| 20:15.46 | andrei_il | is there any other lemon and re2c importer that I could look and perhaps , understand better? I couldn't find any in src/conv |
| 20:24.50 | brlcad | andrei_il: did you try grepping for END_EXAMPLE ? |
| 20:24.57 | brlcad | it's in a header |
| 20:25.38 | brlcad | notes that "END_EXAMPLE;" is technically injecting a stray semi-colon ... boo |
| 20:29.00 | sofat | brlcad, I have some question regarding my milestone. milestone is "provide the authority to user to contribute new document. " my question regarding CMakeList.txt file means who is update this file user or admin(online). |

| 20:35.47 | andrei_il | ups, didn't thought of searching there, thanks. But how is it injecting a semi-colon ? I see that its concatenating "\n\\endcode\n\n" to &appData->description |
| 20:35.48 | brlcad | sofat: ideally anyone, but I don't think this is a priority to work on next -- maybe not at all for gsoc |
| 20:36.12 | brlcad | andrei_il: your END_EXAMPLE macro is different than the one I was looking at |
| 20:36.54 | sofat | brlcad, means |
| 20:38.22 | andrei_il | so its just a substitute for some code |
| 20:38.39 | brlcad | andrei_il: bingo |
| 20:39.30 | brlcad | arguably unnecessary complexity for this very reason |
| 20:39.43 | brlcad | macro layering can cause confusion, especially for macros only used few times |
| 20:40.14 | bhollister | brlcad: i have the proc-db/nmgmodel.c as an exemplar. however, my routine currently has a check for ID_NMG. so, applying cmface to models produced via nmgmodel return without effect. when using nmg models produced via 'make,' there is a problem in a call to nmg_findeu(). am trying to verify face addition with cface instead, since the routine returns without error, just no visible geometry. |
| 20:40.34 | andrei_il | got it, I will try not to use them ,if possible |
| 20:40.58 | sofat | brlcad, I am not understand. |

| 20:41.33 | brlcad | bhollister: one of us misunderstands :) |
| 20:42.25 | brlcad | bhollister: you overarching goal involves implementing a command-line way to create nmg objects ... I'm interested in seeing an example of what that looks like (or will look like) |
| 20:42.54 | brlcad | otherwise, adding all those nmg files to src/libged isn't right... :) |
| 20:43.34 | brlcad | sofat: I'm saying forget about that milestone for now |
| 20:43.56 | sofat | ok |
| 20:43.56 | brlcad | sofat: focus on the other points that starseeker mentioned a couple weeks ago |
| 20:45.17 | sofat | ok |
| 20:47.54 | bhollister | brlcad: yes. i believe the best way is for the interface not to provide the same level of user control as the internal api. likely, subcommands that map to adding vertex uses, etc. will be removed. right now, adding faces to achieve a simple object needs to work. so i've been using the make command that already exists for the initial nmg object, and then alteration of that. |
| 20:47.54 | ih8sum3r | The feedback form that had a validation problem is made using formspree.io and in that it doesn't support the validations for safari so need to change it completely. |
| 20:49.24 | bhollister | brlcad: there's something fundamental to the nmg object from make that isn't allowing the application of cmface at the moment, or how i'm handling the vertex list provided for nmg_cmface. |
| 20:51.15 | bhollister | brlcad: perhaps the best way is to build up a model from nmg_mm, first adding regions and shells after a null model has been created. that can be done with the subcommands. |
| 20:51.56 | bhollister | brlcad: then track down what might be missing in the subcommand impl of ged_nmg_cmface |
| 20:53.14 | brlcad | bhollister: but do you have a mock up of what that interface is going to look like? a design? |
| 20:53.59 | brlcad | I get that you're struggling with a cface issue that's frustrating, I'm asking about the bigger picture direction |
| 20:54.33 | brlcad | is your plan to expose the nmg api as is first, and then see what you can eliminate? |
| 20:54.47 | bhollister | brlcad: for the most part yes. |
| 20:56.31 | bhollister | brlcad: perhaps add some higher level functionality. the nmg api provides the ability to add faces only. everything else is very fundamental and doesn't apply to the CLI. |
| 20:57.57 | bhollister | brlcad: we can add verts, edges and n gons via a variable number of verts passed to cmface subcommand |
| 20:58.01 | brlcad | I would like to see a design of the higher level functionality before you go implementing it |
| 20:58.34 | brlcad | (if you get that far) |
| 20:59.15 | bhollister | okay. i'd like to get cmface subcommand working first. |
| 21:00.08 | bhollister | since adding faces is certainly part of the high-level subcommand list. |
| 21:03.45 | brlcad | sounds good |
| 21:04.05 | brlcad | if you really get stuck (i.e., spent a couple days, no progress), send a shout out |
| 21:04.14 | brlcad | might see something you're missing |
| 21:05.30 | bhollister | brlcad: cool. in terms of the mock up, can you give me an example of the sort of higher level routines you have in mind for manipulations on the nmg objects beyond what the internal nmg api offers? |
| 21:06.26 | brlcad | it's really a question of how one might want to describe a polygonal object manually |
| 21:06.34 | brlcad | solid polygonal object |
| 21:07.16 | brlcad | I could see something that automatically fuses just given face descriptions |
| 21:07.29 | brlcad | since the strings will match exactly if the points were intended to be coincident |
| 21:07.41 | brlcad | so you could define a box with something like... |
| 21:08.42 | bhollister | i see. so functions that facilitate an object creation by minimizing the amount of numerical data needing to be provided |
| 21:09.25 | bhollister | or that take existing data in the object already, and doing the same |
| 21:09.29 | brlcad | in nmg nmg face 0 0 0 0 1 0 1 1 0 0 1 0 face 0 1 0 0 1 1 etc |
| 21:09.43 | bhollister | got it. |
| 21:09.47 | brlcad | either way |
| 21:09.55 | brlcad | could be an nmg command that lets you incrementally build it up |
| 21:10.22 | brlcad | probably will need subcommands that let you validate/solidify |
| 21:11.35 | bhollister | is there perhaps an example of these with other CAD systems in use? |
| 21:13.13 | brlcad | I don't know of any CAD system that lets you do this :) |
| 21:14.13 | brlcad | the way https://en.wikipedia.org/wiki/Polygon_mesh covers the topic is pretty canonical though |
| 21:14.45 | brlcad | support definition of vertices, edges, faces |
| 21:15.06 | brlcad | could be the way to go for starters |
| 21:17.30 | brlcad | bhollister: have you read this: http://www.google-melange.com/gci/task/view/google/gci2014/5546966268248064 |
| 21:18.00 | brlcad | resulted in this: http://brlcad.org/wiki/NMG |
| 21:18.33 | brlcad | that low-level without the tcl {} wrapping may be the way to go initially |
| 21:33.00 | bhollister | brlcad: thanks. these docs should be useful. i had not seen them previously. |
