| 02:48.53 | starseeker | kunigami: is it building tcl? |
| 02:49.17 | starseeker | if that's a CMake build, can you post again with make VERBOSE=1 ? |
| 02:50.20 | kunigami | starseeker: right, I'll do that in a minute. I went back to r45780 and it seems fine (r5797 gives a compile error too) |
| 02:50.45 | starseeker | kunigami: it's very probably the tweaks I made to the tcl/tk build system |
| 02:51.07 | starseeker | kunigami: you're on a mac? which version of OSX? |
| 02:51.39 | kunigami | I'm on on mac 10.6 |
| 02:51.44 | starseeker | huh |
| 02:52.00 | starseeker | what's your cmake configure line? |
| 02:52.18 | kunigami | starseeker: cmake ../brlcad -DBRLCAD-ENABLE_OPENGL=OFF -DBRLCAD-ENABLE_COMPILER_WARNINGS=OFF -DBRLCAD-ENABLE_ALL_LOCAL_LIBS=ON -DBRLCAD-ENABLE_OSL=ON -DCMAKE_INSTALL_PREFIX=/Users/kunigami/dev/brlcad-bin/ -DBRLCAD-ENABLE_STRICT=OFF |
| 02:53.42 | starseeker | huh. yeah, if you can post the whole thing (that plus make VERBOSE=1 ) that should help |
| 02:54.47 | kunigami | here it is: http://paste.ubuntu.com/660214/ |
| 02:59.24 | starseeker | kunigami: um. can you try it again from a clean build directory? |
| 02:59.50 | starseeker | eg cmake <options> && make VERBOSE=1 |

| 14:46.43 | brlcad | abhi2011: looking good ... does it work? |
| 14:49.12 | brlcad | one change I'd like to request .. "runphysics" sounds too quirky, too ambiguous |
| 14:49.12 | abhi2011 | umm no brlcad :( |
| 14:49.19 | brlcad | almost like "do science" |
| 14:49.24 | abhi2011 | haha :) |
| 14:49.38 | abhi2011 | "simulate" |
| 14:49.42 | ``Erik | "teh winz: |
| 14:50.01 | brlcad | that's exactly what I was going to suggest, "simulate" is better and extends to other operations in the future |
| 14:50.11 | abhi2011 | right |
| 14:50.18 | abhi2011 | so regarding the code |
| 14:50.43 | abhi2011 | its seems that rt_matrix_transform() takes an input combination and returns an output combination |
| 14:50.59 | brlcad | okay |
| 14:51.00 | abhi2011 | but what would be better is to directly act on the input |
| 14:51.03 | ``Erik | sips his irish coffee in celebration of a successful oil change and tire rotation (next time, imma just pay someone to do it) |
| 14:51.16 | abhi2011 | change its attributes so it gets drawn in the new position |
| 14:51.49 | brlcad | abhi2011: are you saying that the output combination is not the same as the input combination? |
| 14:51.58 | ``Erik | thought rt_matrix_transform() just called the f_xform() field for the primitive, it did NOT operate at the comb level... but I may misrecall |
| 14:52.17 | abhi2011 | brlcad : well I think so |
| 14:52.39 | abhi2011 | because when I add it to the db then it shows an error |
| 14:52.59 | abhi2011 | http://bin.cakephp.org/view/1614988156 |
| 14:53.24 | brlcad | ``Erik: it calls into the object functab |
| 14:53.29 | abhi2011 | I call the output combination as translated_solid |
| 14:53.32 | brlcad | (combs are registered as objects) |
| 14:53.39 | ``Erik | ah, did not know that |
| 14:53.49 | ``Erik | do combs recursively pass the xform? |
| 14:54.10 | ``Erik | xpush style? |
| 14:54.35 | brlcad | I don't recall, but I don't think so |
| 14:54.54 | brlcad | just calls the generic transform |
| 14:55.10 | ``Erik | sets the comb matrix and returns, ok |
| 14:55.19 | ``Erik | might be a pertinent detail to abhi's stuff |
| 14:55.25 | brlcad | which does an import with a matrix applied |
| 14:55.59 | brlcad | abhi2011: what is translated_solid? |
| 14:56.03 | brlcad | "l translated solid" |
| 14:56.11 | brlcad | er, "l translated_solid" |
| 14:56.23 | abhi2011 | its the output of rt_matrix_transform() |
| 14:56.36 | brlcad | no |
| 14:56.38 | abhi2011 | i add the output of rt_matrix_transform() to the database |
| 14:56.40 | brlcad | run that command in mged |
| 14:57.15 | abhi2011 | yes the command adds it to the database |
| 14:57.24 | brlcad | *sigh* |
| 14:57.25 | brlcad | no |
| 14:57.33 | brlcad | run ... "l translated_solid" ... in mged |
| 14:57.39 | abhi2011 | oh ok |
| 14:58.04 | ``Erik | most mged commands are simple wrappers to the C library |
| 14:58.35 | ``Erik | so "what does this mean" can be easily experimented with by doing mged cmds |
| 15:00.19 | brlcad | from that pastebin listing, it looks like translated_solid is wrong -- it's not recognized as a comb yet giving a subtree failure |
| 15:00.57 | abhi2011 | ya seems that way |
| 15:00.59 | abhi2011 | http://bin.cakephp.org/view/1112923952 |
| 15:01.02 | brlcad | I wouldn't worry about making a copy just yet -- try updating the original object |
| 15:01.36 | brlcad | interesting |
| 15:01.37 | abhi2011 | ok , then rt_matrix_transform() output should be copied into the original object |
| 15:01.55 | brlcad | rt_matrix_transform applied the change to the original object |
| 15:01.59 | brlcad | you just have to write it out to disk |
| 15:02.16 | brlcad | look at the other places where rt_matrix_transform() is called, see what else they're doing |
| 15:02.39 | abhi2011 | yes |
| 15:03.02 | abhi2011 | the translate and rotate commands apply vector math to do their thing |
| 15:03.40 | abhi2011 | I was looking at chgmodel.c for how these commands work |
| 15:04.22 | brlcad | I believe you just feed rt_matrix_transform() the same rt_db_internal pointer for both input and output |
| 15:05.11 | brlcad | then it'll either be written to disk, or you'll call an export function (e.g., rt_db_put_internal()) to write it |
| 15:05.26 | abhi2011 | oh its that simple....:P |
| 15:05.46 | brlcad | it's something close to that simple |
| 15:07.15 | abhi2011 | yes after getting the output from rt_matrix_transform() , I call db_diradd() to get the directory pointer and then rt_db_put_internal() to put the internal format of the combination to the disk |
| 15:08.33 | ``Erik | brlcad: I think I have the new machine cleaned up and about ready to look at migration again, the hiccup with the weird dep thrashing everything is fixed |
| 15:09.44 | ``Erik | (if not zomfg migration, I'd appreciate the crit. name being moved so'z I don't have to remember #'s :D ) |
| 15:14.04 | brlcad | nods |
| 15:19.34 | abhi2011 | YES!!!! :) |
| 15:19.40 | abhi2011 | just moved it |

| 20:46.54 | abhi2011 | ok I get a strange behavior when I link the simulate command with a command wrapper |
| 20:47.28 | abhi2011 | so I have modified cmd.c to include a new command wrapper for the new mged command "simulate" |
| 20:48.05 | abhi2011 | cmd.c now has the implementation for cmd_ged_simulate_wrapper(ClientData clientData, Tcl_Interp *interpreter, int argc, const char *argv[]) |
| 20:48.18 | abhi2011 | its very similar to the cmd_ged_edit_wrapper() |
| 20:49.11 | abhi2011 | http://bin.cakephp.org/view/1859715979 |
| 20:49.48 | abhi2011 | in the command wrapper I call the libged function which actually implements the simulate function : ged_simulate(struct ged *gedp, int argc, const char *argv[]) |
| 20:50.24 | abhi2011 | i call ged_simulate() 100 times from the command wrapper with an artificial delay inserted of 1/10th of a second |
| 20:51.51 | abhi2011 | ged_simulate() is called inside a for loop and I draw the object at the new position as well at the end of each iteration, so it should appear to move every 1/10th of a second in mged |
| 20:52.36 | abhi2011 | but the object is moved only at the end of all the iterations when the command wrapper returns |
| 20:53.10 | abhi2011 | I would have expected mged to draw the object immediately after the cmd_draw() is called to draw the object |
| 20:58.41 | abhi2011 | so the way the simulate command should work is , the user gives the number of steps to simulate as : simulate 10 |
| 20:59.17 | abhi2011 | and then the physics takes over and simulates with the command wrapper for simulate called the libged simulate implementation 10 times |
| 21:00.14 | abhi2011 | but after each call to the libged simulate function ged_simulate(), the position of the dynamic object should be redrawn in mged and not after all the iterations are complete |
| 21:00.14 | ``Erik | command sounds about right, I believe there is a "flush" type command that has to be passed to force display |
| 21:00.25 | abhi2011 | aoh |
| 21:00.35 | abhi2011 | right i ll check it |
| 21:31.23 | abhi2011 | there is a update_views = 1; probably that one |
| 21:54.48 | ``Erik | I tend to avoid gui code, but that sounds familiar. I think there was maybe discussion about an explicit "block until" flush cmd? I'm not sure :/ |
| 21:55.17 | ``Erik | (the discussion being about if we should implement one, or if the variable is adequate) |
