| 08:54.51 | abhi2011 | hi |
| 08:55.09 | abhi2011 | So I was trying to add a new command yesterday to mged |
| 08:55.18 | abhi2011 | I get this error during the build |
| 08:56.03 | abhi2011 | http://bin.cakephp.org/view/276195617 |
| 08:56.29 | abhi2011 | seems after adding the implementing c function to setup.c, it has to be also declared somewhere |
| 08:59.07 | bhinesley | abhi2011: lets see your setup.c line again |
| 08:59.32 | abhi2011 | {"tire", cmd_ged_plain_wrapper, ged_tire}, |
| 08:59.34 | abhi2011 | <PROTECTED> |
| 08:59.36 | abhi2011 | <PROTECTED> |
| 08:59.53 | abhi2011 | the 2nd lie was added by me |
| 09:00.39 | abhi2011 | i think ged_runphysics has to be declared in libged somewhere |
| 09:01.14 | abhi2011 | maybe after i changed the implementation name in the c file |
| 09:01.27 | abhi2011 | I have to declare it in a related header |
| 09:02.28 | bhinesley | there are a ton of places for new commands to be "declared", for various uses. It's kind of a dark art. Try adding a line to the cmd_tab in src/libtclcad/tclcad_obj.c |
| 09:03.31 | bhinesley | not sure if that will do you any good since you're trying to add it to mged only |
| 09:03.47 | abhi2011 | ok i will try that |
| 09:04.49 | abhi2011 | but are you sure there is no header file like src/libged/runphysics.h required for the newly added src/libged/runphysics.c |
| 09:05.17 | bhinesley | yes, actually, I just recalled what it is you probably need: include/ged.h |
| 09:05.31 | abhi2011 | i do have it included |
| 09:05.38 | abhi2011 | let me paste the code 1 sec |
| 09:06.21 | abhi2011 | http://bin.cakephp.org/view/1016518663 |
| 09:08.03 | bhinesley | Oh, right... I meant that you probably need to add a ged_runphysics declaration to the file include/ged.h |
| 09:08.04 | abhi2011 | but ged.h does not have a declaration of the new function in runphysics.c , |
| 09:08.05 | abhi2011 | int |
| 09:08.06 | abhi2011 | ged_runphysics(struct ged *gedp, int argc, const char *argv[]) |
| 09:08.11 | bhinesley | nods |
| 09:08.13 | abhi2011 | ok |
| 09:11.09 | abhi2011 | by the way, what does wdb routine mean |
| 09:11.14 | abhi2011 | came across them in ged.h |
| 09:12.21 | bhinesley | search HACKING for libwdb |
| 09:12.35 | abhi2011 | right :) |
| 09:13.57 | abhi2011 | cool the build resumed again |
| 09:14.14 | bhinesley | cool |

| 09:33.20 | CIA-62 | BRL-CAD: Updated several helper functions to work with a recent change from automatic |
| 09:33.20 | CIA-62 | BRL-CAD: arguments in union edit_cmd to pointers. Added command-specific functions to |
| 09:33.20 | CIA-62 | BRL-CAD: initialize the needed argument pointers. Fixed a problem with the help |
| 09:33.20 | CIA-62 | BRL-CAD: subsystem, and eliminated a bit of redundancy. More edit() testing, but not a |
| 09:33.20 | CIA-62 | BRL-CAD: whole heck of lot of foreward progress yet. |

| 12:18.36 | abhi2011 | success!! |
| 12:18.41 | abhi2011 | new command added :P |
| 12:22.10 | abhi2011 | I was wondering, regarding mged application wrappers |
| 12:22.32 | abhi2011 | so suppose i have written a simple application that say just prints hello world |
| 12:22.45 | abhi2011 | now I want to integrate it into mged |
| 12:23.48 | abhi2011 | so I would insert code in libged like |
| 12:23.50 | abhi2011 | int |
| 12:23.51 | abhi2011 | ged_runphysics(struct ged *gedp, int argc, const char *argv[]) |
| 12:24.51 | abhi2011 | so i guess i would need to migrate the c code to the wrapper c file inside libged |
| 12:25.29 | abhi2011 | it would not be possible for mged to call my precompiled program and direct its output to its own output in the mged window ? |
| 12:26.51 | abhi2011 | and also provide it input through the argc, argv[] arguments that is generally used to receive command line parameters by c programs ? |
| 12:29.30 | abhi2011 | hmm I guess not, such a thing would need to be done by the wrapper function if at all required |

| 13:53.47 | brlcad | kunigami_: ah, that makes a lot more sense! |
| 13:55.27 | brlcad | looks like there's a curious bias, though -- I'd expect surface reflectivity to be fairly constant for the flat surfaces |
| 13:56.10 | brlcad | looks more like it's showing the relative amount of energy reflected |
| 13:57.58 | brlcad | abhi2011: you could call a preompiled program and direct output to the mged window (several mged commands do exactly that) ... it's just bad design |
| 13:58.20 | brlcad | and for a physics engine integration, you really don't want unnecessary overhead |
| 13:58.53 | brlcad | needs to be tight and fast so you could call it 20 times a second without delay |

| 15:14.06 | abhi2011 | right i ll insert it as a command in mged |
| 15:14.51 | abhi2011 | right now I am checking with a checked out copy of brlcad, whether i can compile and install bullet with it and start the physics through a command |
| 15:15.11 | abhi2011 | so bullet has it own sources of course |
| 15:15.31 | abhi2011 | where would you generally place the sources for an external library, in the src tree i mean |
| 17:35.02 | ``Erik | src/other/ usually... but until it's end user ready, it might be better to say "hey, developers, you need bullet installed to use it" |
| 18:37.01 | abhi2011 | right ok |
| 18:37.10 | abhi2011 | so i have got bullet installed and running now |
| 18:37.39 | abhi2011 | will proceed to write add it to the runphysics command |
| 18:37.42 | abhi2011 | but before that |
| 18:38.11 | abhi2011 | is there any command or app wrapper that access the list of objects in mged |
| 18:38.17 | abhi2011 | i want to se how its done |
| 18:38.50 | abhi2011 | because say the user has drawn a sphere, then I would need its dimensions to insert it in the physics world and run a simulation |
| 18:49.52 | abhi2011 | hmm...I am using the autotools build, I have included a new Bullet header now to the new command I had added to mged earlier (by modifying tire.c in src/libged) |
| 18:50.52 | abhi2011 | the new header is #include <btBulletDynamicsCommon.h> , and its already been placed in /usr/local/include/bullet during Bullet installation |
| 18:51.05 | abhi2011 | but apparently bullet does not look here for headers |
| 18:51.19 | abhi2011 | have to modify the build logic to make sure it does |
| 18:55.33 | abhi2011 | any idea where exactly can add this so it appears as a -I/usr/local/include/bullet compiler option during the build |
| 19:03.20 | CIA-62 | BRL-CAD: 03starseeker * r45732 10/brlcad/trunk/CMakeLists.txt: Provide an option to allow RPMS to have a version-specific unique name, to make it simpler to allow for installing multiple versions of BRL-CAD on one system. |
