| 14:54.06 | brlcad | hello Alexandrus |
| 14:54.11 | Alexandrus | hello brlcad |
| 14:54.16 | Alexandrus | i have a simple question |
| 14:54.33 | Alexandrus | how do you modell a tube with sqare ends |
| 14:54.38 | Alexandrus | (flat ends) |
| 14:55.39 | brlcad | that'd be two overlapping arb8's making a + then cylinders down the sides to round the edges |
| 14:56.20 | Alexandrus | so a great number of cylinders |
| 14:56.30 | Alexandrus | thought maybe there is a tgc mod hidden somewhere |
| 14:56.33 | brlcad | well, great number == 4 |
| 14:56.38 | Alexandrus | 4? |
| 14:56.41 | brlcad | 4 |
| 14:56.49 | brlcad | 2 arb8's and 4 rccs |
| 14:57.20 | Alexandrus | ok, the 2 arb8's for the ends |
| 14:57.25 | Alexandrus | but the 4 rccs??? |
| 14:57.30 | Alexandrus | one for the tube |
| 14:57.32 | Alexandrus | and 3? |
| 14:57.37 | brlcad | no no |
| 15:00.01 | Alexandrus | http://kccm.dnsalias.org:8080/sketch1.png |
| 15:00.02 | brlcad | so consider the shape in 2d first |
| 15:00.20 | brlcad | two *overlapping* rectangles, then circles on the corners |
| 15:00.27 | brlcad | like this http://www.jeremydjohnson.com/images/post_images/2008/11/box_sections.gif |
| 15:01.20 | brlcad | you diagram is just a slightly more complicated for where you have multiple bends, but the exact same idea applies |
| 15:01.58 | Alexandrus | the problem is the smooth interval between section 1-2 and 2-3 |
| 15:02.13 | Alexandrus | i don't see how i do this with rcc |
| 15:02.27 | Alexandrus | or tor.. |
| 15:03.16 | brlcad | imagine that in that image, sections 1+2+3 ARE the first arb8 rectangle |
| 15:03.17 | Alexandrus | guess maybe i need an example |
| 15:03.54 | brlcad | then there's another overlapping arb8 crossing through the other two horizontal sides and section 2 |
| 15:03.58 | brlcad | those are unioned together |
| 15:04.14 | Alexandrus | not seeing the use of a second arb8, but ok.. |
| 15:04.21 | Alexandrus | now we have a "cross" |
| 15:04.25 | brlcad | a "+" |
| 15:05.34 | Alexandrus | ah, i see what you mean... |
| 15:06.08 | Alexandrus | guess this doesn't work with constant surface though |
| 15:06.25 | Alexandrus | (seen from end to end, surface must stay constant) |
| 15:06.40 | brlcad | what do you mean by constant? |
| 15:06.59 | Alexandrus | very pratical, you get a tube and flatten it (hammer, heat) |
| 15:07.24 | Alexandrus | A(x)=const |
| 15:07.29 | Alexandrus | (approx) |
| 15:08.38 | brlcad | ah, a taper |
| 15:08.49 | Alexandrus | otherwise i could just + the tube with two recs.. |
| 15:08.56 | Alexandrus | hmm... |
| 15:09.04 | brlcad | you can make that work, that's just a tgc with different ends |
| 15:09.26 | brlcad | rcc == tgc with equal ends, tgc is generalized where they're not equal |
| 15:09.36 | Alexandrus | hmm |
| 15:09.44 | Alexandrus | and then plus |
| 15:10.06 | Alexandrus | ok, this might work.. |
| 15:11.41 | Alexandrus | still...i think 1 arb8, one rcc and two tgc's should do the job |
| 15:11.50 | Alexandrus | unless i have forgotten something |
| 15:12.10 | Alexandrus | yes...the cut...another rcc and two tgc |
| 15:14.07 | brlcad | so sort of like this: http://www.cemframework.com/img/CrusaderSolid.png |
| 15:14.33 | Alexandrus | hmm...just much more soft |
| 15:14.47 | Alexandrus | i could try using two outer tgc at one end |
| 15:15.05 | Alexandrus | to get a smooth curve from rcc to arb8 |
| 15:15.10 | brlcad | yeah, the cylinder would taper and there's another arb8 that would run tangent at 90 degrees, then a big arb8 in the middle to fill it in |
| 15:15.44 | Alexandrus | the second arb8 isn't necessary to what i can see now |
| 15:16.17 | Alexandrus | i will try modelling it |
| 15:16.56 | brlcad | for a 4-sided rounded edge tube, you will have to use at least 3 arb8's and 4 tgc's |
| 15:17.37 | brlcad | or 5 arb8's and 4 tgcs for a more optimally oranized tube with minimally overlapping primitives |
| 15:18.10 | brlcad | at least in order to capture an arbitrary taper |
| 15:18.13 | brlcad | depends on the shape |
| 15:18.29 | Alexandrus | i guess i will just modell one end first |
| 15:18.31 | Alexandrus | show it to you |
| 15:18.38 | Alexandrus | and you give me advice on how to improve it |
| 15:18.59 | Alexandrus | the second end is equal, so shouldn't be a problem |
| 15:42.40 | CIA-43 | BRL-CAD: 03starseeker * r40022 10/brlcad/branches/cmake/ (3 files in 2 dirs): Ah, handy - Ogre has FindCarbon and FindCocoa files - add them in. There may be a few other items of interest in Ogre's CMake packages. |
