| 17:12.17 | aaronkramer | hey I am back |
| 17:12.30 | aaronkramer | i need help with brl-cad again |
| 17:12.53 | brlcad | hello aaronkramer |
| 17:13.01 | aaronkramer | I booted it once and it worked fine then I exited tried to boot it a few days later and it is giving me this error |
| 17:13.11 | aaronkramer | Initializing and backgrounding, please wait...Done |
| 17:13.12 | aaronkramer | no display name and no $DISPLAY environment variable |
| 17:13.12 | aaronkramer | MGED Aborted |
| 17:13.23 | brlcad | same problem you had the first time |
| 17:13.24 | aaronkramer | sorry just a sec |
| 17:13.26 | aaronkramer | yea |
| 17:13.28 | brlcad | run from xterm, not Terminal |
| 17:13.55 | brlcad | make sure X11 is running |
| 17:14.04 | aaronkramer | I try to run mged from xterm but it does not work |
| 17:14.10 | aaronkramer | it says command not found |
| 17:14.17 | brlcad | run /usr/brlcad/bin/mged |
| 17:15.21 | aaronkramer | okay it, that works |
| 17:15.25 | aaronkramer | why does it do that |
| 17:16.41 | aaronkramer | and what is a good manual for brl-cad |
| 17:21.29 | brlcad | that gets into just explaining how the unix command line paths work |
| 17:21.34 | brlcad | has nothing to do with brl-cad really |
| 17:22.12 | brlcad | when you run a command, whether it be "mged" or "ls" or "whatever" on the command line .. it searches through a list of directories/folders throughout your filesystem |
| 17:22.20 | brlcad | that list of places is called your PATH |
| 17:22.46 | brlcad | pretty much every operating system has a concept of a PATH that is searched when you run a command, even Windows |
| 17:23.21 | brlcad | BRL-CAD installs into the /usr/brlcad folder, with binaries in the /usr/brlcad/bin folder .. which is not in your PATH of folders searched by default |
| 17:23.47 | brlcad | so you have to either add it to your PATH or you have to specify the full location of the binary application that you're trying to run |
| 17:23.58 | brlcad | which is why /usr/brlcad/bin/mged works |
| 17:24.36 | aaronkramer | in xterm how would I make it so that all I have to do is type mged |
| 17:24.51 | aaronkramer | or is there a way to create a launcher like in linux for mac os x |
| 17:27.05 | brlcad | there are several ways to make "launchers" under mac os x |
| 17:27.18 | aaronkramer | would I use apple script? |
| 17:27.31 | brlcad | but one of the easiest for what you're trying to do would be to add it to the X11 menu |
| 17:27.45 | brlcad | select Applications -> Customize Menu |
| 17:28.00 | brlcad | click the Add button |
| 17:28.02 | aaronkramer | where |
| 17:28.06 | brlcad | in X11 |
| 17:28.20 | brlcad | make X11 the focused app |
| 17:28.31 | brlcad | then up on the menu, select Applications -> Customize Menu |
| 17:29.05 | aaronkramer | then I just put in the command then what I want it to be named |
| 17:29.36 | brlcad | reverse that, but yes |
| 17:29.48 | brlcad | first column is the menu name, second is the command |
| 17:30.28 | aaronkramer | I see |
| 17:30.45 | brlcad | try "/usr/brlcad/bin/mged -f" as the command |
| 17:31.35 | aaronkramer | I didn't work with the -f |
| 17:31.45 | aaronkramer | it worked without it though |
| 17:31.53 | brlcad | really? that's odd .. ok |
| 17:32.36 | brlcad | the other way to make it so that typing "mged" works is to modify your PATH setting |
| 17:32.38 | aaronkramer | actually it didn't work with either |
| 17:33.00 | aaronkramer | how do I do that |
| 17:33.02 | brlcad | hm, I've heard that the X11 launcher is a bit buggy |
| 17:33.25 | aaronkramer | Yea I heard from various sources that mac also killed X11 in mac os x |
| 17:33.57 | brlcad | run this command: ls -lad .??* | grep -i profile |
| 17:34.01 | brlcad | what does it report? |
| 17:34.22 | brlcad | that's a listing of files that start with a "." looking for any profile files |
| 17:34.50 | brlcad | should see either .profile or .bash_profile |
| 17:34.50 | aaronkramer | -rw-r--r-- 1 aaronkra aaronkra 264 Jan 10 18:51 .profile |
| 17:34.55 | brlcad | okay |
| 17:34.59 | brlcad | cat .profile |
| 17:35.37 | brlcad | that displays the contents of the .profile file |
| 17:35.45 | brlcad | what's in there? |
| 17:36.12 | aaronkramer | -rw-r--r-- 1 aaronkra aaronkra 264 Jan 10 18:51 .profile |
| 17:36.21 | aaronkramer | oops |
| 17:36.24 | aaronkramer | sorry |
| 17:36.26 | aaronkramer | it says |
| 17:36.52 | aaronkramer | export PATH=/usr/brlcad/bin:$PATH |
| 17:37.12 | brlcad | ah, so someone already helped you add it to your path |
| 17:37.29 | aaronkramer | possibly |
| 17:38.02 | aaronkramer | so why wouldn't it work |
| 17:38.06 | brlcad | run this: open -e .profile |
| 17:38.13 | brlcad | that will open up the with in TextEdit |
| 17:38.20 | brlcad | add a line that says this: |
| 17:38.24 | brlcad | export DISPLAY=:0 |
| 17:38.30 | brlcad | save the file |
| 17:39.12 | aaronkramer | okay |
| 17:39.16 | aaronkramer | done |
| 17:39.25 | brlcad | now you can type "mged" from Terminal |
| 17:39.38 | aaronkramer | I already could as long as x11 was open |
| 17:40.28 | aaronkramer | it gives me the same error when I type it in from terminal with x11 closed |
| 17:40.31 | brlcad | only because I made BRL-CAD 7.10.4 on Mac OS X specifically try to search for X11 |
| 17:40.38 | brlcad | yeah, X11 has to be running |
| 17:40.55 | brlcad | we've not made a release that doesn't need it (though one is being worked on) |
| 17:41.18 | aaronkramer | cool |
| 17:41.31 | aaronkramer | will it ever move away from CMDUI |
| 17:41.58 | aaronkramer | CMDLUI* |
| 17:42.32 | brlcad | one of the major efforts is to make it more "gui-friendly" |
| 17:42.43 | brlcad | more user-friendly in general with a new look |
| 17:43.03 | aaronkramer | that would be really nice |
| 17:43.10 | brlcad | the command line will never go away, but you won't necessarily *have* to use/learn it to be productive |
| 17:43.22 | aaronkramer | yea |
| 17:43.25 | brlcad | just like how mac os x has a command line, but you don't necessarily have to learn it |
| 17:43.49 | brlcad | as for documentation/tutorials, they're on the website: http://brlcad.org/ |
| 17:43.59 | aaronkramer | okay |
| 17:44.01 | brlcad | Documentation section .. I'd suggest just going down the list in order |
| 17:44.42 | brlcad | the really big one is the "Introduction to MGED" |
| 17:44.46 | aaronkramer | About BRL-CAD's features, I heard it had a chemical library that let you define the composition of a component is that true |
| 17:44.54 | aaronkramer | okay |
| 17:45.02 | aaronkramer | i think I will download all of those as back up |
| 17:45.05 | brlcad | that's the extensive introduction that takes you through tutorial after tutorial that will give you instruction on the basics |
| 17:46.26 | brlcad | not sure what you mean by chemical library -- we coordinate, hook into, and are USED by several major analysis packages (including for ballistics, optics, chem, bio, radar signature, V/L, etc) |
| 17:47.27 | brlcad | you can specify an objects material properties in brl-cad for computation of things like mass/weight, centroids, volume, etc |
| 17:47.41 | aaronkramer | thats pretty cool |
| 17:48.40 | brlcad | the material property basically boils down to the modeler specifying a list of material densities, marking objects as being a given material type, and then running one of our tools that performs calculations that use the material information (rtweight, g_qa, others) |
| 17:49.02 | brlcad | rtarea for projected presented coverage areas if you're looking at profile information |
| 17:49.16 | brlcad | rtcheck and g_qa for overlap/interference computations |
| 17:49.33 | aaronkramer | what renderer does it use |
| 17:51.52 | brlcad | we have a variety of renderers |
| 17:52.31 | brlcad | there's a wireframe render in mged, there are various ray-tracers (rt, rtedge) |
| 17:53.29 | brlcad | as a real quick tutorial, you can run this: mged /usr/brlcad/share/brlcad/7.10.4/db/havoc.g |
| 17:53.39 | brlcad | then in the mged command window type: e havoc |
| 17:53.56 | brlcad | then type: rt -s 1024 |
| 17:54.02 | brlcad | then type: rtedge -s 1024 |
| 17:54.35 | brlcad | (there are ways to do that all via the gui, but much easier to explain/describe it as commands |
| 17:55.39 | brlcad | got to run off, so best of luck on the tutorials -- they really are essential *just* to get a grasp of the basics |
| 17:56.09 | aaronkramer | see ya |
| 17:56.11 | aaronkramer | and thanks |
| 17:56.37 | brlcad | sure, btw, you should see something like: http://brlcad.org/images/havoc_rtedge.png after that last step |
