| 00:20.03 | brlcad | you need to find where it stopped, it'll say why |
| 00:20.11 | brlcad | so scan down towards the end |
| 00:20.29 | brlcad | look for "compiler cannot create working executables" |
| 00:21.17 | brlcad | those other WARNING lines are important too, but they're certainly not the ones halting the build |
| 00:22.24 | alvaro1 | i found it http://fpaste.org/paste/11705 |
| 00:22.41 | brlcad | great |
| 00:22.48 | brlcad | now look at the lines that preceed it |
| 00:22.54 | brlcad | it ran some test and it failed |
| 00:23.20 | brlcad | might be immediately before, might be several dozen before |
| 00:25.35 | alvaro1 | http://fpaste.org/paste/11706 |
| 00:25.40 | alvaro1 | must be here |
| 00:26.32 | brlcad | and you are correct |
| 00:26.37 | brlcad | so what's the problem? |
| 00:27.13 | alvaro1 | the heaader is wrong |
| 00:27.17 | brlcad | nope |
| 00:27.32 | alvaro1 | /* confdefs.h. */ |
| 00:27.36 | brlcad | what does line 1 say it's doing |
| 00:28.54 | alvaro1 | checking g++ compiler and flags for sanity |
| 00:29.05 | brlcad | right |
| 00:29.14 | brlcad | so it's going to make sure the compiler works |
| 00:29.33 | brlcad | line 2 is the command it runs to test if the compiler works |
| 00:29.44 | brlcad | then what happens? |
| 00:31.01 | alvaro1 | so the problem is the compiler |
| 00:31.13 | alvaro1 | or headers |
| 00:31.51 | brlcad | don't jump .. what happened after it tried to run that command it showed on line 2 ? |
| 00:32.27 | brlcad | read line 3 |
| 00:33.44 | alvaro1 | i must install g++ |
| 00:34.13 | brlcad | :) |
| 00:34.45 | brlcad | "compiler cannot create working executables" .. because you don't even have the compiler |
| 00:35.50 | alvaro1 | arm-gp2x-linux-gcc-c++.i386 : Cross Compiling GNU G++ targeted at arm-gp2x-linux |
| 00:35.50 | alvaro1 | avr-gcc-c++.i386 : Cross Compiling GNU GCC targeted at avr |
| 00:36.00 | alvaro1 | can i use any of those? |
| 00:36.46 | brlcad | depends on your hardware -- do you have arm or avr? |
| 00:37.00 | alvaro1 | do not have a clue ... |
| 00:37.04 | brlcad | heh |
| 00:37.13 | brlcad | well then it sounds like it's a no probably |
| 00:37.23 | brlcad | what's your os? |
| 00:37.30 | alvaro1 | f10 |
| 00:37.42 | alvaro1 | fedora 10 |
| 00:37.44 | brlcad | how do you normally install software? |
| 00:37.49 | alvaro1 | yum |
| 00:38.21 | brlcad | try just: yum install gcc-c++ |
| 00:38.51 | brlcad | or yum install g++ |
| 00:39.11 | alvaro1 | <PROTECTED> |
| 00:39.15 | brlcad | but I suspect just yum install gcc-c++ |
| 00:39.19 | brlcad | that looks like it |
| 00:39.50 | alvaro1 | brlcad: thanks |
| 00:39.56 | brlcad | no problem |
| 00:40.39 | alvaro1 | if it runs can i upload it to the home page of brlcad |
| 00:41.03 | brlcad | only if you go through all the steps to make a proper yum package :) |
| 00:41.35 | brlcad | and/or a proper rpm |
| 00:41.57 | brlcad | there are dozens if not hundreds of tutorials on how to make an rpm |
| 00:42.09 | brlcad | quick web search is a wealth of knowledge |
| 00:42.21 | brlcad | you could certainly become the rpm maintainer, though :) |
| 00:43.15 | alvaro1 | i thought only as an "copy to /usr" version |
| 00:44.55 | brlcad | mm, that's possible too, though you'll have to build with specific configure options and create some symlinks |
| 00:45.07 | brlcad | and build from a tagged version |
| 00:45.31 | alvaro1 | <PROTECTED> |
| 00:45.56 | brlcad | actually it's not |
| 00:46.05 | brlcad | just sounds easier because there are tutorials |
| 00:46.19 | brlcad | you'd still have to go through the same steps, specific configure options |
| 00:46.27 | brlcad | part of release management |
| 00:46.44 | brlcad | so the settings on distributions are consistent |
| 00:47.31 | brlcad | ``Erik: heh, now *this* build is going to take a long time.... on a Linksys NSLU2 |
| 00:48.11 | brlcad | about 2/3rds the speed of an old SGI O2, 32MB memory .. been compiling all day and it's still in the middle of openNURBS :) |
| 00:50.14 | alvaro1 | http://fpaste.org/paste/11708 it seems to be built |
| 00:51.00 | alvaro1 | brlcad: http://fpaste.org/paste/11708 |
| 00:53.02 | brlcad | curious, why do you redirect output to 'a'? |
| 00:54.28 | brlcad | the most important warning there is the first one, that the Xi library was not found -- you need to install that |
| 00:54.39 | alvaro1 | http://fpaste.org/paste/11709 here is a |
| 00:54.50 | brlcad | I don't want 'a' |
| 00:54.56 | brlcad | I want to know why you redirect to 'a' |
| 00:55.55 | alvaro1 | because the terminal has not enough buffer capabilities, and in order to keep it all i redirect it to a |
| 00:56.18 | brlcad | okay, fair enough |
| 00:57.03 | brlcad | if you want to capture all output together, you can do this: ./configure --enable-optimized > a 2>&1 |
| 00:57.23 | brlcad | that "2>&1" will put the stderr with the stdout like you see when the command is run without a redirect |
| 00:57.27 | brlcad | that can be done for any command |
| 00:57.35 | brlcad | just so you know |
| 00:57.53 | brlcad | so install libXi and you should hopefully be good to go |
| 00:58.04 | brlcad | (rerun configure to verify that the warning goes away) |
| 00:58.49 | alvaro1 | i already tiped "make" |
| 00:59.04 | alvaro1 | it is running "make" |
| 00:59.43 | alvaro1 | is libXi important ? |
| 01:03.01 | Mike111 | hi brlcad |
| 01:03.47 | Mike111 | I've looked at the channel log. any luck tracing the problem I've got? |
| 01:07.12 | *** join/#brlcad Mike111 (n=mike@cadil21.kaist.ac.kr) |
| 01:12.07 | *** join/#brlcad Mike111 (n=mike@cadil21.kaist.ac.kr) |
| 01:12.30 | brlcad | Mike111: did you try that 'make CFLAGS...' I suggested a couple days ago? |
| 01:12.44 | brlcad | alvaro1: what did the warning say? |
| 01:12.55 | brlcad | (don't paste it, read it) :) |
| 01:13.14 | Mike111 | brlcad: you mean the one with the burst? |
| 01:13.31 | brlcad | Mike111: I don't recall exactly which directory |
| 01:13.56 | brlcad | but the suggestion was to add a cflag that might have resolved the link failure |
| 01:14.14 | Mike111 | in your email you mentioned: "cd src/ |
| 01:14.15 | Mike111 | burst && make CFLAGS=../libfb/libfb.la" and see if that makes any |
| 01:14.15 | Mike111 | difference. |
| 01:14.27 | Mike111 | I've tried this but am getting the same error |
| 01:14.40 | brlcad | exact same error? |
| 01:14.47 | brlcad | or just failed in some other way? |
| 01:14.54 | alvaro1 | brcad: This will likely result in a build failure. |
| 01:15.05 | Mike111 | same error: those X_24 references |
| 01:15.10 | brlcad | alvaro1: so you tell me, does libXi sound important? :) |
| 01:15.31 | brlcad | it's "likely" that it's important, but feel free to ignore the warning :) |
| 01:15.43 | alvaro1 | brlcad: i must stop "make" |
| 01:15.52 | brlcad | alvaro1: or wait for it to fail |
| 01:15.55 | brlcad | then install it |
| 01:15.58 | brlcad | then run make again |
| 01:16.08 | brlcad | Mike111: okay, hm |
| 01:16.19 | brlcad | Mike111: it's failing for you in src/burst, yes? |
| 01:16.37 | alvaro1 | brlcad: is not a problem to interrupt make? |
| 01:16.51 | brlcad | alvaro1: no, you could do that too -- doesn't matter |
| 01:17.35 | Mike111 | brlcad: I'll paste the lines again |
| 01:17.47 | brlcad | Mike111: heh, you're doing the same as alvaro1 :) |
| 01:18.01 | brlcad | the lines say, you really don't need to paste them :) |
| 01:18.24 | brlcad | have to read them .. just seems foreign at first but it's actually english ;) |
| 01:18.48 | Mike111 | Then how will you know where exactly it fails? |
| 01:18.56 | Mike111 | if I don't paste the error outputs? |
| 01:19.31 | brlcad | because it halts where it fails, you read it, you tell me |
| 01:20.57 | Mike111 | the last directory make entered was brlcad-7.14.6/src/bwish |
| 01:21.22 | brlcad | you're welcome to *also* pastebin the output ... just really shouldn't get the (bad/common) habit of pasting when something unexpected happens _instead_ of reading the output ;) |
| 01:21.39 | brlcad | okay, good to know |
| 01:21.50 | Mike111 | it then run gcc with lots of files and options and then reports ./../src/libtclcad/.libs/libtclcad.so: undefined reference to `X24_close_existing' |
| 01:22.01 | brlcad | nods |
| 01:22.33 | brlcad | I'm 70% sure that's the fault of the debian devs .. messing with libtool |
| 01:23.01 | brlcad | which leaves a lot of room for uncertainty and still doesn't fix anything for you :) |
| 01:23.32 | brlcad | so the issue per that message is libtclcad |
| 01:24.01 | brlcad | that X24_... symbol should be coming from our libfb library but for whatever reason libtool isn't linking it in |
| 01:24.31 | brlcad | more than likely it's just an ordering issue, but one fix should be to verify/force libfb to link into libtclcad |
| 01:24.34 | brlcad | so try this: |
| 01:24.39 | brlcad | cd src/libtclcad |
| 01:25.16 | Mike111 | ok I'm there |
| 01:27.10 | brlcad | what does this report: grep TCLCAD Makefile | grep libfb | wc |
| 01:28.03 | Mike111 | 1 218 3233 |
| 01:28.17 | brlcad | okay, and this: grep dependency libtclcad.la |

| 01:30.09 | brlcad | hm, okay that looks right |
| 01:30.39 | Mike111 | the config.log file lists several errors: |
| 01:30.46 | Mike111 | conftest.c:12:28: error: ac_nonexistent.h: No such file or directory |
| 01:30.55 | brlcad | that's normal |
| 01:30.58 | Mike111 | configure: failed program was: |
| 01:30.59 | Mike111 | | /* confdefs.h. */ |
| 01:31.02 | brlcad | it runs thousands of tests |
| 01:31.09 | Mike111 | ok |
| 01:31.12 | brlcad | some/many are supposed to fail, some aren't |
| 01:31.31 | brlcad | it basically probes your environment to figure out what it looks like |
| 01:32.10 | brlcad | "does this look like cygwin? .. no. does the compiler work? .. yes. .. etc" |
| 01:32.29 | brlcad | hundreds/thousands of tests |
| 01:32.31 | Mike111 | It also lists that will build the tcl, tk and itcl/itk libraries although I've installed tcl8.4 and tcl8.5, tk8.4 and tk8.5 and itcl |
| 01:32.43 | brlcad | separate issue, one at a time :) |
| 01:32.51 | brlcad | probably because of itcl |
| 01:33.03 | brlcad | you can't build itcl without also building tcl/tk |
| 01:33.17 | brlcad | as itcl uses (uninstalled) private tcl/tk sources |
| 01:33.29 | Mike111 | these are the packages I've installed: |

| 01:34.35 | brlcad | and way too much for a channel paste |
| 01:35.36 | brlcad | so next step since everything looks right is to figure out what the *exact* compile line looks like |
| 01:35.54 | brlcad | <PROTECTED> |
| 01:36.08 | Mike111 | ok |
| 01:36.09 | brlcad | run make and make sure it fails with the symbol error |
| 01:36.31 | Mike111 | looks like the same error |
| 01:37.02 | Mike111 | symbol error you mean the undefined reference (like `X24_close_existing')? |
| 01:37.29 | brlcad | yes |
| 01:37.43 | brlcad | make LIBTOOL=../../libtool |
| 01:37.47 | brlcad | pastebin that output |

| 02:12.23 | brlcad | going to have to pick up on this later, out of time now |
| 02:12.41 | brlcad | starseeker: dunno but .. BUGS! :) |
| 02:14.02 | Mike111 | http://pastebin.bzflag.bz/m27d9c9f2 |
| 02:14.02 | brlcad | is intently being more attentive about documenting issues and ideas as they come up |
| 02:14.24 | starseeker | ok, looks like I probably won't squash it tonight |
| 02:14.43 | starseeker | is more disturbed that it suddenly broke without (apparently) anything in coil changing... |
| 02:15.21 | brlcad | Mike111: yeah, that file looks fine .. so this is basically off in truely bizzaro land without some more interactive time |
| 02:15.47 | Mike111 | that's good news ;) |
| 02:15.49 | brlcad | Mike111: best solution is to await the results of my build here to see if I can at least reproduce it |

| 02:19.00 | brlcad | wtf .. okay, so the first time through, they weren't there and now they are.... |
| 02:19.29 | brlcad | looks like this is not a clean build, like you first compiled through with different configure options or make options |
| 02:19.36 | brlcad | either way, it's there now |
| 02:19.39 | brlcad | cd ../bwish |
| 02:19.39 | brlcad | make |
| 02:19.43 | brlcad | should link |
| 02:20.08 | Mike111 | no errors now : |
| 02:20.10 | Mike111 | :) |
| 02:20.20 | brlcad | slaps Mike111 around a bit for unclean build :) |
| 02:20.27 | brlcad | cd ../.. |
| 02:20.27 | brlcad | make |
| 02:20.33 | brlcad | see if it complete |
| 02:21.03 | brlcad | if it does not: make distclean && sh autogen.sh && ./configure --enable-all && make |
| 02:21.12 | Mike111 | no sure what you mean by an unclean build, but yesterday I've removed configure, configure.stat and vonfigure.cache, ran autogen.sh and then configure and make |
| 02:21.31 | brlcad | that sounds probably unclean |
| 02:21.55 | starseeker | 's first rule in situation like this - clean checkout :-) |
| 02:21.57 | brlcad | you had object files in there for a different build configuration |
| 02:23.05 | Mike111 | wouldn't removing configure, config.{stat,cache} and running autogen.sh sort of start from scratch? |
| 02:23.32 | brlcad | nope |
| 02:24.16 | brlcad | "make distclean" is "close" to starting from scratch but even that isn't exactly the same |
| 02:24.23 | Mike111 | well, that was an advice I got on the channel, but nevermind. |
| 02:24.40 | brlcad | it many situations, that'll work, but it's just not the same and in this case was the problem |
| 02:25.16 | brlcad | suspect you ran configure earlier and you didn't have libX11 or libXi ? |
| 02:25.26 | Mike111 | is there something more extensive than make distclean, that is make it an absolute `clean' build? |
| 02:25.30 | brlcad | or at least it didn't detect it |
| 02:25.57 | brlcad | sure, check out the sources from the repository or unpack them from a source distribution tarball |
| 02:26.05 | brlcad | that's about as "clean" as it gets ;) |
| 02:26.24 | brlcad | from repository is the cleanest |
| 02:26.38 | brlcad | from a source tarball, after running make distclean |
| 02:26.51 | brlcad | depends where in the build pipeline you want to end up |
| 02:27.10 | Mike111 | so basically I need to remove the currently installed directories, download the source again and install it? |
| 02:27.15 | brlcad | patiently waits for "sh autogen.sh && ./configure --enable-all --enable-optimized --prefix=/usr/brlcad/rel-7.14.8 && make distcheck && make && make install && make benchmark && make test" to complete |
| 02:27.36 | Mike111 | I refer to using a repository |
| 02:27.38 | brlcad | before posting up a new source tarball |
| 02:27.53 | brlcad | then yeah, just checking out again is the best way to go |
| 02:28.18 | Mike111 | ok, I'll try building it now |
| 02:28.28 | brlcad | please do post up a follow-up to your thread posting if it works so others are aware |
| 02:28.42 | brlcad | if not, try the distclean rebuild |

| 02:36.14 | Mike111 | how long does make run for? |
| 02:36.28 | starseeker | depends on system |
| 02:36.42 | starseeker | 20, 30 minutes or more sometimes |
| 02:37.20 | Mike111 | in the meantime, maybe you could help me with another issue |
| 02:39.03 | brlcad | that's 20-30 minutes per file if you're compiling on an XScale ;) |
| 02:39.33 | Mike111 | how do I create a solid which is made of smoothly connected cross sections, where the cross sections are defined by polynomials (generated in another application) |
| 02:39.34 | brlcad | fastest I've seen is 2 minutes, average on modern desktop is around 10-20 min |
| 02:40.23 | brlcad | sounds like a great question for starseeker |
| 02:40.31 | brlcad | alas, I'm spent and gotta run, ttyl |
| 02:40.46 | Mike111 | tnx for your help brlcad :) |
| 02:40.48 | brlcad | depending on the polynomial, entirely doable |
| 02:40.52 | brlcad | sure, np |
| 02:41.01 | Mike111 | I'll post a followup on the make |
| 02:41.20 | brlcad | thx |
| 02:41.34 | starseeker | Mike111: primitives in BRL-CAD are described as implicits |
| 02:41.47 | starseeker | so your polynomials have to be expressible as a surface of a primitive |
| 02:42.32 | Mike111 | the polynomials define only a 2-D cross section (one poly. for upper surface and one for lower surface) |
| 02:42.33 | starseeker | then you constrain the intersection points of multiple primitives at the intersection points to be "smooth" via forcing derivatives to be the same at intersection points |
| 02:42.58 | starseeker | so... you want to extrude the 2-D cross sections? |
| 02:43.33 | Mike111 | extrude, as I understand it, is simply copying the same cross section along an axis |
| 02:43.43 | starseeker | right |
| 02:43.55 | Mike111 | I want the surface to smoothly blend from one cross section to another |
| 02:43.55 | starseeker | the more general case is sweep, but that's not a primitive we have yet |
| 02:44.30 | starseeker | so you have a series of 2D sketches, and you want a "smooth" surface that connects one sketch to the next? |
| 02:44.37 | Mike111 | right |
| 02:44.55 | starseeker | erm. sounds like an application of fillets or some such. |
| 02:45.17 | starseeker | I don't think we have anything that can do what you're thinking right now |
| 02:45.44 | Mike111 | :( |
| 02:46.02 | starseeker | is there an example graphic online somewhere of a similar shape? |
| 02:46.08 | starseeker | easier to tell from that |
| 02:47.07 | Mike111 | say for example a wing, which has one cross section (airfoil) at the tip and another airfoil at the root (where it connects to the hull) |
| 02:47.10 | starseeker | wonders WHY the compile on the XScale but is sorta afraid to ask... |
| 02:47.24 | starseeker | nods |
| 02:48.47 | starseeker | in that case, I would use rpc or rhc primitives for sections of the leading edge of the wing |
| 02:48.58 | starseeker | an epa or ehy primitive to define the tip |
| 02:49.30 | starseeker | and more shallow rpc primitives to define the middle surface of the wing, aligning them with the edge primitives |
| 02:49.52 | starseeker | to ensure smoothness, you'd have to do some derivative constraints |
| 02:50.35 | starseeker | actually, for a wing edge you might do better with a tec primitive, come to think of it |
| 02:51.02 | starseeker | sees if he can make a quick mockup example |
| 02:59.46 | starseeker | Mike111: OK, take a look at this: http://bzflag.bz/~starseeker/wingshape.png |
| 03:00.02 | starseeker | it's obviously not a true wing, but it does suggest how you might get started |
| 03:00.10 | starseeker | that uses two primitives |
| 03:01.12 | starseeker | for a true airfoil shape you'd want something more flexible (like NURBS, which we're working on) but you could actually get a fairly decent looking wing out of combinations of those primitives |
| 03:02.10 | Mike111 | are the cross section ellipses? |
| 03:02.15 | starseeker | yes |
| 03:02.48 | Mike111 | I need to use airfoil shapes |
| 03:03.13 | starseeker | can you show me an example cross section? |
| 03:03.29 | Mike111 | sure, can you hold for a moment? |
| 03:03.33 | starseeker | yes |
| 03:06.11 | starseeker | are you thinking along these lines? http://en.wikipedia.org/wiki/File:PSU-90-125.PNG |
| 03:06.40 | Mike111 | I've got a PNG file. how can I send it to you? |
| 03:06.56 | starseeker | um. can you put it up on the brlcad wiki? |
| 03:07.21 | starseeker | http://brlcad.org/wiki/Main_Page |
| 03:07.58 | Mike111 | it looks similiar to the wikipedia link |
| 03:08.01 | starseeker | Mike111: how exact does your airfoil shape have to be? |
| 03:09.03 | starseeker | the airfoil can be approximated with a boolean combination of tec and ehy primitives, but it probably wouldn't be "exactly" the airfoil cross section. |
| 03:09.09 | Mike111 | pretty accurate. the whole purpose if to test some specific shapes so it's not just for an illustration purpose |
| 03:09.34 | starseeker | ok. yeah, that sounds like an application where nurbs surfaces would be required |
| 03:10.14 | starseeker | ponders the possibility of a proc-db that does wing shapes using tec/ehy... hmm... |
| 03:10.36 | starseeker | Mike111: for exact, continuous and complex surfaces of that sort primitives usually aren't what's needed |
| 03:11.12 | starseeker | (one of the reasons the automobile has modeled with NURBS for so long, for example - car body exteriors don't map well to geometric primitives) |
| 03:11.44 | Mike111 | that makes sense. what can we do? |
| 03:12.01 | starseeker | we're working on getting raytracing of NURBS working in BRL-CAD now |
| 03:12.26 | Mike111 | I read in volume III there a b/w extrude feature for arbitrary shapes |
| 03:12.38 | starseeker | yes, but that's just an extrusion |
| 03:13.04 | starseeker | the wing shape is curved in all three dimensions |
| 03:13.47 | Mike111 | let say in a simpler case, where I just want to extrude along a path (without cross section changes) |
| 03:14.07 | starseeker | for that, you can define a 2D sketch and extrude it |
| 03:14.43 | Mike111 | can I extrude along a curved path? |
| 03:14.52 | starseeker | not currently |
| 03:14.56 | starseeker | that would be sweep |
| 03:15.40 | Mike111 | when do u expect the nurbs feature to be available? |
| 03:16.00 | starseeker | hard to say. editing support will follow raytracing |
| 03:17.38 | Mike111 | do u another opensource application which can do this now? |
| 03:17.45 | Mike111 | do u know another opensource application which can do this now? |
| 03:18.13 | starseeker | If you really need to work with nurbs, you might take a look at Ayam: http://ayam.sourceforge.net/ - they're not a CAD application though, so I don't think you get things like solidity |
| 03:19.14 | Mike111 | I need to export the wing as an IGES file (or DXF etc.) |
| 03:19.24 | Mike111 | can I use ayam and import into brlcad? |
| 03:19.44 | starseeker | if you export as dxf, we import dxf |
| 03:19.54 | starseeker | remember though, that's not a format that supports nurbs |
| 03:20.09 | Mike111 | what about IGES? |
| 03:20.41 | starseeker | I believe it has some nurbs support, but our convertor uses our old nurbs structures currently. (Plus, I doubt Ayam exports IGES) |
| 03:21.03 | Mike111 | so what can I do? |
| 03:21.38 | Mike111 | the ayam webpage shows: File formats (r/w): RIB, DXF, 3DM, 3DMF, OBJ, X3D. |
| 03:22.10 | starseeker | If you want to help push NURBS in support in BRL-CAD, you could take a look at the IGES convertor and see about getting it to export OpenNURBS data structures instead of what it currently supplies. |
| 03:22.29 | starseeker | For immediate, fully open source editing of NURBS as NURBS... |
| 03:22.41 | starseeker | let me check something... |
| 03:25.23 | starseeker | you might want to take a look a gCAD3D, but it's not clear to me if they are open source or not |
| 03:26.51 | starseeker | apparently they can open the OpenMoko CAD files, but I can't say what other abilities it may have |
| 03:29.17 | Mike111 | can I smoothly connect cross sections in brlcad, for example by creating many adjacent ones? |
| 03:29.57 | starseeker | yes, if you force the derivatives at the intersecting points to be equal |
| 03:30.11 | Mike111 | how do I do that? |
| 03:30.15 | starseeker | it's not easy |
| 03:30.18 | starseeker | currently |
| 03:30.41 | starseeker | work is going on on a libpc constraint library that would help support things like that, but it's (again) a feature in development |
| 03:31.00 | starseeker | if you really want to have a go at it, you can see how the tire tool alligns elliptical tori |
| 03:31.29 | starseeker | similar problems would need to be solved for the primitives used to make up the wing shapes |
| 03:31.55 | starseeker | it's an interesting problem, but I'm dubious it could be good enough for what you're after |
| 03:32.28 | Mike111 | I can't see a tire command in the command reference (Vol. II) |
| 03:32.36 | starseeker | it's new |
| 03:33.03 | starseeker | the source is in brlcad/src/libged/tire.c |
| 03:36.10 | Mike111 | help tire gives `no help found for tire' but that's on 7.10.4 |
| 03:38.53 | starseeker | ah, yes |
| 03:38.57 | starseeker | It appeared later |
| 03:39.56 | starseeker | http://brlcad.svn.sourceforge.net/viewvc/brlcad/brlcad/trunk/src/libged/tire.c?revision=34402&view=markup |
| 03:41.51 | starseeker | the difficulty with something like an airfoil is that the curvature between each "maximum" point is quite subtle and it may very well be that for your purposes our primitives currently just don't have the expressive power |
| 03:42.35 | starseeker | I might be able to get "close" to an airfoil shape with a LOT of work on a proc-db, but I wouldn't presume to think it was actually aerodynamically valid |
| 03:42.58 | Mike111 | well, I hope brlcad will soon have the nurbs feature |
| 03:43.16 | starseeker | it's our top development priority |
| 03:43.25 | starseeker | or one of them |
| 03:43.49 | starseeker | keep an eye on us :-) |
| 03:44.03 | Mike111 | I guess I need to find another interim solution until this feature is added |
| 03:44.05 | Mike111 | will do :) |
| 03:47.30 | starseeker | makes a note to check coil behavior before and after the fix to pipe.c incrementing... |
| 03:47.38 | starseeker | and heads outta here |
