| 13:00.59 | d-lo | brlcad: Meeting at 1400 FYI |
| 13:01.03 | tc-rucho | or brlcad does not have this feature (yet)? |

| 13:16.07 | brlcad | d-lo: alrighty |
| 13:17.04 | brlcad | tc-rucho: doesn't have feature edits like those two at the moment |
| 13:20.01 | brlcad | there are some commands that assist, like blending a cylinder, rounding off the end, rounding a box, and a few others, but not specifically chamfer and fillet as feature edits |
| 13:20.12 | brlcad | you have to just apply the negative boolean |
| 13:20.54 | tc-rucho | I would like to know how to do that on this model: http://tc-rucho.homelinux.net/webcam.g |
| 13:21.43 | tc-rucho | I really wonder what was brlcad specifically used for in the 20 years it's been arround |
| 13:22.55 | tc-rucho | I have a hole in a sphere, and want to chamfer that |
| 13:23.17 | tc-rucho | doing it with bolean subtract or intersect would be really rough |
| 13:29.08 | d-lo | you just want the opening in the hole (in the sphere) to have a 45 degree chamfer? |
| 13:30.18 | tc-rucho | d-lo: more or less, actually, rounded edge, but if you check the model I just linked, you will see _why_ this would be a really tough task if only manual boolean operations were used |
| 13:30.34 | tc-rucho | d-lo: just open it and B orbita.c |
| 13:31.13 | tc-rucho | I've already done some chamfer here and there using trc |
| 13:31.40 | tc-rucho | but this case it's different |
| 13:31.58 | tc-rucho | I have decentered holes in a sphere |
| 13:32.09 | tc-rucho | that makes a double-convex edge |
| 13:32.26 | d-lo | hrm, can't hit that addy you linked |
| 13:32.51 | tc-rucho | maybe the dns is screwed up, I'll use the ip instead |
| 13:33.14 | tc-rucho | http://190.191.172.28/webcam.g |
| 13:33.15 | tc-rucho | there |
| 13:33.50 | tc-rucho | d-lo: I recommend you to do a view aet 75 30 0 |
| 13:33.54 | tc-rucho | and render |
| 13:35.23 | tc-rucho | I want to fillet/chamfer the holes in carcaza.c |
| 13:35.44 | tc-rucho | B carcaza.c; rt -M -F0 -w 1669 -n 784 -V 2.128826530612245 -C0/0/50 -P16 -H0 -J0 -l0 |
| 13:35.54 | tc-rucho | that will give you an idea of the problem |
| 13:36.29 | d-lo | thanks, but I have a decent handle on the commands ;) |
| 13:36.37 | tc-rucho | (: |
| 13:36.45 | d-lo | firstly, I need to comment on the tree struct you have going. |
| 13:36.53 | tc-rucho | it sucks, right? |
| 13:37.02 | tc-rucho | first time drawing anything in brlcad |
| 13:37.15 | tc-rucho | so, tell me, what's wrong with it |
| 13:37.18 | d-lo | in order for something to *exist*, it needs to be in a region. |
| 13:37.48 | d-lo | inside carcaza.c, there are two solids that do not belong to a region. This invalidates the csg. |
| 13:38.10 | tc-rucho | o..k..? |
| 13:38.13 | tc-rucho | why? |
| 13:38.36 | tc-rucho | are you telling me I should make combinations of only regions? |
| 13:39.03 | d-lo | thats the simple explaination. Better than what I was typing lol |
| 13:39.29 | d-lo | In order for a primitive to *be* something, it needs to have Material information associated with it. |
| 13:39.43 | d-lo | and the only way for a primitive to get that is to belong to a region. |
| 13:40.30 | d-lo | currently esfera-externa.s and esfera-eterna-menor.s do not belong to a region, so technically they don't exist. |
| 13:41.05 | tc-rucho | ok, and what's all this for? |
| 13:41.20 | d-lo | for valid csg modeling. |
| 13:41.30 | tc-rucho | ok |
| 13:41.33 | tc-rucho | fixes the tree |
| 13:42.00 | tc-rucho | I don't think this helps for the chamfer thing in carcaza.c |
| 13:42.27 | tc-rucho | however, if it will save me troubles in the future, I'll apply it |
| 13:42.42 | d-lo | I would think that carcaza.c should become a region... |
| 13:43.03 | d-lo | ranura-superior.r and ranura-frontal.r should become combinations. |
| 13:43.15 | tc-rucho | why? |
| 13:43.37 | tc-rucho | what I still don't get is why isn't it valid to do bolean operations between regions |
| 13:45.42 | d-lo | Well CSG modeling, in my opinion, is best approached from a Reality perspective. |

| 13:45.58 | d-lo | if you are going to make a hole in a piece of wood.... |
| 13:46.20 | d-lo | then youwould subtract from that wood |
| 13:47.00 | d-lo | it would be rather silly to make a cyl out of another piece of wood and *then* try to make that cyl become a hole in the wood. |
| 13:47.25 | d-lo | With your model, you have a sphere that you are subtracting various things from it |
| 13:47.45 | d-lo | the sphere exists, but you are using other prims to subtract from it. |
| 13:47.59 | d-lo | I am probably not explaining this very well, lol |
| 13:49.10 | tc-rucho | not really.. that was just to keep track of the objects. See, I'm not very comfortable with having to name every object I create. So in order to keep track of them I group the primitives I intend to use for subtraction |
| 13:49.16 | tc-rucho | or for everything else |
| 13:49.44 | tc-rucho | so I can then do x object and see where does it belong |
| 13:50.03 | tc-rucho | if you have a better way I'd like to hear about it |
| 13:50.28 | tc-rucho | I come from AutoCAD, never named a shit, just modelled |
| 13:50.35 | d-lo | heh :) |
| 13:50.40 | d-lo | whats your email addy? |

| 13:55.16 | bitminer | for thoes interested in wik docbook. I am going to try and install this on my server today. |
| 13:55.51 | d-lo | tc-rucho: the chamfer on that, will indeed, be a tough one ;) |
| 13:56.48 | d-lo | getting a nice smooth one atleast. |
| 13:57.35 | tc-rucho | d-lo: see what I meant (: I did some basic chamfer on camara.r but this was a totally different task |
| 14:02.45 | tc-rucho | I'm checking the .g database format definition in order to see if chamfer/fillet operations could be added without breaking backwards compatibility. Once I figure out how 'ev' works and some other stuff here and there, maybe I'll implement a fillet/chamfer function. Still, I will have to do a lot of research to acomplish that |
| 14:04.18 | tc-rucho | d-lo: shall we continue this later? It's time for me to go, I'll be back in about 5 hours |
| 14:04.22 | d-lo | beveling on an edge like that could be done with BoTs, but then you lose the true roundness |
| 14:04.32 | d-lo | I just emailed you |
| 14:04.45 | d-lo | moved the region levels around a bit and took care of two overlaps. |
| 14:05.19 | d-lo | kk. I might be here :) |
| 14:06.49 | d-lo | to any crypto gurus: If you have the unencrypted data and the encrypted data, is it difficult (or possible) to derive the key used for that encryption? |
| 14:11.58 | brlcad | depends on what cipher was used |
| 14:12.20 | d_rossberg | d-lo: it depends on the encryption algorithm: it is very hard for the usual asymmetric public key algorithms to dereive the secret key (e.g.) |
| 14:12.29 | brlcad | brute force, you search the keyspace encrypting until you match the encrypted |
