| 08:48.56 | d_rossberg | furthermore i'm afraid you are on the wrong way with the combination thing |
| 08:49.16 | d_rossberg | but i need to analyse it more deeper |
| 08:49.41 | d_rossberg | i would expect it to be much simpler than you think |
| 08:50.11 | Zhao_Anqing | d_rossbery: thank you so much sincerely. Yes, I guess I mistake something about this part according to your E-mail. |
| 08:51.38 | pandrei | daniel: got some( a lot of question) regarding the class implementation |
| 08:51.41 | pandrei | got time for it? |

| 09:06.27 | ankesh11 | vladbogo_: I faced the same problem. There are two fixes you can use, either use a smaller sized image or use an external site such as Imgur and provide the link in the wiki. |
| 09:08.34 | d_rossberg | Zhao_Anqing: how about working on the other open things first? E.g. nmg_clone_shell() doesn't work |
| 09:09.07 | d_rossberg | pandrei: you could simply ask and wait for an answer ;) |
| 09:09.51 | Zhao_Anqing | OK. get it. I will check this function now. |
| 09:09.55 | pandrei | I would have, but many questions are follow-up |
| 09:13.38 | d_rossberg | pandrei: ok, let me start: ConstSegment and Segment should be virtual |
| 09:14.17 | d_rossberg | you cannot create them, only the derived classes can be created |
| 09:15.34 | d_rossberg | i.e. virtual Type() with "= 0" in segment and implemented in the derived classes |
| 09:17.47 | pandrei | so, by being virtual you mean they have no fields |
| 09:17.49 | pandrei | and no constructors |
| 09:18.52 | d_rossberg | no, and no: it can have constructors and member variables but they can be used by the derived classes only |
| 09:19.19 | *** join/#brlcad teepee- (bc5c2133@gateway/web/freenode/ip.188.92.33.51) |
| 09:19.41 | d_rossberg | and this is because it has a function which isn't defined in the parent class |
| 09:20.29 | pandrei | shouldn't I declare the methods with virtual then? |
| 09:20.46 | d_rossberg | however, then i see another problem: the ownership of the objects |
| 09:21.19 | d_rossberg | yes, you could declare the Type() as virtual |
| 09:21.42 | pandrei | with the Type() I was having trouble returning an enum |
| 09:21.53 | pandrei | I still haven't figure why it works in Combination but not in Sketch |
| 09:21.59 | pandrei | figured* |
| 09:22.47 | d_rossberg | the Type would be easy: Line returns line, Arc arc etc. |
| 09:23.34 | pandrei | yes, I figured that out, I had/have an issue with the compiler |
| 09:23.44 | pandrei | in order to return that, I have to typedef the enum |
| 09:23.56 | pandrei | as I get " seg_type is not a type" |
| 09:24.02 | pandrei | but, nevermind, I ll find a way to handle that |
| 09:24.22 | d_rossberg | another possibility would be the usage of a call-back function |
| 09:24.31 | pandrei | I'm more concerned about getting a class structure we can agree on, so I can progress |
| 09:26.48 | d_rossberg | ther is the ownership and an performance issue with this solution |
| 09:27.33 | d_rossberg | it works only if the objects are handled with pointers to instances living on the heap |
| 09:27.45 | pandrei | I might be stupid but I don't understand why Segment/ConstSegment aren't interfaces? |
| 09:28.31 | d_rossberg | they are interfaces, why not |
| 09:28.50 | pandrei | well, the way we have discussed them so far |
| 09:29.03 | pandrei | my understanding was that they're abstract classes |
| 09:29.14 | *** join/#brlcad caen23 (~caen23@92.83.166.162) |
| 09:29.16 | pandrei | because if I put start and end point in Seg/ConstSeg |
| 09:29.24 | pandrei | then you would have get/set for them |
| 09:29.49 | d_rossberg | an interface is abstract in general ;) |
| 09:30.04 | pandrei | but an interface shouldn't contain any code? |
| 09:30.15 | d_rossberg | you can have an interface and different implementations behind it |
| 09:30.28 | d_rossberg | it depends |
| 09:31.19 | pandrei | I've got an idea |
| 09:31.49 | d_rossberg | fine :) |
| 09:31.54 | pandrei | rather than having a full header implementantion and then move on to class implementantion. What if I make a patch just with Segment/ConstSegment |
| 09:32.04 | pandrei | it's faster for you to review, then when I get it right |
| 09:32.06 | pandrei | we move on |
| 09:34.05 | d_rossberg | i'm afraid we need something similar to Object/ObjectCallback in ConstDatabase |
| 09:35.25 | pandrei | I'm afraid I don't understand what you mean by that :( |
| 09:39.47 | d_rossberg | objects on the heap have issues with ownership and performance |
| 09:41.34 | d_rossberg | they have to be deleted: who is resposible for this? and the allocation on the heap is (relatively) time expensive |
| 09:45.28 | pandrei | uhm, C++ doesn't have garbage collection |
| 09:45.33 | pandrei | so I assume the object has to delete itself |

| 16:32.28 | ishwerdas | I am working on my renderer |
| 16:32.41 | harmanpreet | okay |
| 16:32.44 | ishwerdas | and I uploaded few obj files by |
| 16:32.50 | ishwerdas | converting them using g-obj |
| 16:33.06 | ishwerdas | but they kind of come tilted by default |
| 16:33.22 | ishwerdas | other obj files from softwares like blender come straight in the center |
| 16:33.29 | ishwerdas | why is it so ? |
| 16:35.38 | ishwerdas | if I correct these files like by rotating them 90` as it's done in previous OGV code |
| 16:35.51 | ishwerdas | then other files would suffer the rotation |
| 16:36.42 | *** join/#brlcad piyushparkash (~piyushpar@117.205.75.145) |
| 16:37.11 | harmanpreet | it's because in ThreeJS Y-axis denotes the "up and down" (vertical) whereas in BRL-CAD it is z-axis |
| 16:38.27 | ishwerdas | is there any work around that you know of, so that we don't have to apply that rotation ? |
| 16:38.58 | harmanpreet | We need to find out. :) |
| 16:39.13 | ishwerdas | hmm |
| 16:39.33 | harmanpreet | are you done with deployment? |
| 16:39.37 | ishwerdas | no! :( |
| 16:39.47 | ishwerdas | I just got my college server |
| 16:39.53 | ishwerdas | with access |

| 16:42.57 | ishwerdas | weird! I was just thinking of the same. |
| 16:43.22 | harmanpreet | Also please, don't work in isolation. |
| 16:43.44 | harmanpreet | Sharing problems are equally important as sharing success. |
| 16:43.47 | harmanpreet | :) |
| 16:44.29 | ishwerdas | I have got another way to show the work until I get a server. I can bundle some sample models along with my app and deploy it on meteor.com, so that no one has to upload models. It's only the uploading part that doesn't work there, rest works like charm. How does that sound for the time being ? |
| 16:45.08 | harmanpreet | Yeah sure! |
| 16:47.24 | ishwerdas | currently almost whole of the previous OGV functionality is ported to meteor |
| 16:47.45 | ishwerdas | except the g-obj conversion, which would be my next milestone |
