| 05:06.37 | Maloeran | Ahah, that just can't be good |
| 05:07.17 | Twingy | it's quite tastey :) |
| 05:08.57 | Maloeran | I'm sure, maybe if you cover the plate with Parmesan Regiano and Romano :) |
| 05:11.12 | Twingy | that would help |
| 05:11.15 | Twingy | but I was on a budget |
| 05:11.25 | Twingy | I moved $4 from my one account to the other |
| 05:11.36 | Twingy | so I technically have $7 I can spend on wed if I need to |
| 05:12.11 | PKMOBILE | whoa youre rich |
| 05:12.16 | PKMOBILE | can i have a $1? |
| 05:12.48 | Twingy | I don't think the ATM spits out $1 bills anymore |
| 05:12.55 | Twingy | or $5 for that matter |
| 05:13.08 | Twingy | only way I can access that money is buying something |
| 05:13.16 | Twingy | that reminds me |
| 05:13.34 | Twingy | you wanna make $25 on evening of nov 1? |
| 05:13.45 | PKMOBILE | how? |
| 05:13.53 | Twingy | helping me make a couple trips to my new house |
| 05:14.00 | PKMOBILE | ok |
| 05:14.16 | Twingy | probly end up moving like a couch, a book case, and maybe something else |
| 05:14.31 | Twingy | and that's about it |
| 05:14.42 | PKMOBILE | im free nov 1 |
| 05:14.58 | Twingy | k, probly like 6:30pm - 8:30pm |
| 05:15.03 | PKMOBILE | ok |
| 05:15.14 | Twingy | I'm renting a truck |
| 05:16.32 | PKMOBILE | ok... may want to remind me when it gets closer |
| 05:17.12 | Twingy | k |
| 05:17.36 | pra5ad | is this offer open to everyone? |
| 05:17.44 | Twingy | everyone but prasad |

| 05:18.24 | Twingy | yep |
| 05:18.47 | Twingy | prasad, I'm gonna get the honda insight |
| 05:18.53 | Twingy | 80mpg |
| 05:18.57 | pra5ad | no fidelity shape-wise until about 14px height |
| 05:19.14 | pra5ad | how long till u recoup cost? |
| 05:19.25 | Twingy | I'll save $1k a year in gas |
| 05:19.38 | pra5ad | do the math |
| 05:19.44 | Twingy | plus $2600 tax credit in '06 |
| 05:19.48 | Twingy | car is $21k |
| 05:20.38 | Twingy | saving about $80 a month it'll pay for the insurance and gas |
| 05:21.20 | Twingy | probly wait till march 1 to get it |
| 05:21.34 | Twingy | I wanna put down atleast $10k to finance it |
| 05:21.52 | Twingy | then jan1 07 I might just pay it off |
| 05:22.52 | Twingy | then I'll end up getting sucked into some kind of relationship |
| 05:23.06 | Twingy | and money will be gone :( |

| 07:41.02 | pra5ad | ohh redundancy.. |
| 07:44.45 | Maloeran | Just ask away, I'm sure someone here can answer |
| 07:46.01 | pra5ad | think i found the answer |
| 07:46.11 | pra5ad | implementing camera strafing |
| 07:46.40 | pra5ad | seems i need the vector perpendicular to the up vector and the view vector |
| 07:46.54 | pra5ad | as in cross product |
| 07:53.10 | pra5ad | how do most ppl manage objects in the scene that require their own transformations? |
| 07:53.39 | pra5ad | do they loadident() -> apply camera transform() -> render object() .. for each object? |
| 07:53.53 | pra5ad | er apply object transform() somewhere in there |
| 07:54.11 | pra5ad | or is there an easier/better way |
| 07:55.22 | Maloeran | Depends of your needs, it's common to maintain a matrix per object and glPushMatrix,glMultMatrix,Render,glPopMatrix for each |
| 07:56.02 | Maloeran | You can follow the same patterns if you have objects with an orientation and position relative to others, you may want to store your rotations as quaternions for more flexibility |
| 07:56.14 | pra5ad | done and done |
| 07:57.55 | pra5ad | just to clarify, the camera transformation has to be mult'ed per object, yes? |
| 07:58.14 | pra5ad | i assume the glmultmat is the camera |
| 07:59.48 | pra5ad | gah .. brain is shutting down |
| 07:59.49 | Maloeran | Yes, you post-multiply the object's matrices by the current modelview matrix, after setting up the eye |
| 08:00.15 | Maloeran | I'm using the opengl vocabulary, this is what you are working with, right? |
| 08:00.21 | pra5ad | yea |
| 08:01.54 | pra5ad | what's the benefit of pushmat in this case? |
| 08:03.17 | Maloeran | Just to restore the previous matrix, to render the following objects |
| 08:06.29 | pra5ad | sample call list: camera.setperspective(does modelview transforms); pushmat(); obj.translate(); obj.render(); popmat(); |
| 08:07.02 | pra5ad | that sequence wont position the obj correctly relative to the eye, yes? |
| 08:08.39 | Maloeran | Why would it not? You have the consider the translation matrix will be multiplied by the current matrix though |
| 08:08.59 | Maloeran | Personally, I find it less bothersome to just manage matrices myself and glLoadMatrix |
| 08:10.20 | pra5ad | ahh |
| 08:14.16 | pra5ad | thanks much =) |
| 08:15.08 | Maloeran | :) Good luck |
| 08:15.59 | pra5ad | fix one more problem and i sleep |
| 08:16.45 | pra5ad | view vector X (0,1,0) .. causes strafing to be x-axis aligned |
| 08:19.16 | Maloeran | Your 3 axis vectors are stored in your "eye" matrix, [2,6,10] is forward |

| 18:56.03 | Maloeran | Hm sorry pra5ad, I think I confused with my ray-tracer's matrix orientation, try [8,9,10] :) and [0,1,2], [4,5,6] for the other axes |
| 19:11.33 | pra5ad | that's funny |
| 19:11.39 | pra5ad | since 2,6,10 works fine |
| 19:13.07 | Maloeran | Ah, good |
| 19:14.39 | Maloeran | You shouldn't have to cross though, use [0,4,8] or [1,5,9] directly for your other axes |

| 19:37.12 | AchiestDragon | realy need it to beable to convert it into dxf with 3d position info ,, do any of the converters give a 3d output ?? |
| 19:39.01 | Twingy | you could try g-stl |
| 19:39.15 | Twingy | I don't think I've ever used g-dxf |
| 19:39.22 | Twingy | but I know dxf-g works, most of the time |

| 20:08.37 | AchiestDragon | may be better haveing a config option where the user can specify one |
| 20:09.54 | brlcad | the user can specify one |
| 20:10.04 | brlcad | EDITOR env var prevails |
| 20:10.20 | brlcad | the issue is supporting configurations where there may not be a suitable system editor |
| 20:10.52 | brlcad | or where there is an expectation of jove as the editor (as brl-cad has shipped jove for over a decade) |

| 20:11.15 | brlcad | phasing it out is probably in order, though |
| 20:11.36 | brlcad | perhaps simply disabling it's compilation by default, instead of the current "compile jove if not detected" behavior |
| 20:12.50 | AchiestDragon | was going to sujest including a editor as there are a number of simple small gnu ones arround , but if it already has one then may as well keep it there |
| 20:13.09 | brlcad | i'm not about to try and force an editor preference on someone, and if they're used to getting jove from brl-cad, so be it |
