| 00:50.26 | starseeker | What operating system are you using? |
| 00:50.38 | killerflo | mac os x 10.4 |
| 00:50.43 | starseeker | Ah. |
| 00:51.11 | starseeker | Not sure where it is there - don't have a Mac handy |
| 00:52.00 | starseeker | Did you build it yourself or use the binary? |
| 00:52.10 | killerflo | binary |
| 00:52.37 | starseeker | Um. Did you put it in the Applications folder? |
| 00:53.34 | killerflo | normaly the programmes are installed in the application folder, but there is nothing new after the installation |
| 00:53.59 | killerflo | so it must be installed somewhere else |
| 00:54.08 | killerflo | but i can't find it |
| 00:54.19 | starseeker | What about a global search for mged |
| 01:02.50 | killerflo | i have a solution |
| 01:03.04 | starseeker | what's that? |
| 01:03.13 | killerflo | i have to run x11 and start it from there |
| 01:03.23 | killerflo | i found it in the folder u said |

| 18:36.32 | starseeker | I was "zooming in" on the cassini model, but it's so tiny |

| 18:38.52 | starseeker | I made a wild remark to brlcad yesterday, and he didn't let me get away with it |
| 18:39.06 | yukonbob | ?What comment? |
| 18:39.11 | yukonbob | *remark |
| 18:39.31 | starseeker | private chat |
| 18:40.38 | starseeker | working on making some docs, and my example model didn't go so hot for what I was calling it. So I said I'd call it Earth |
| 18:40.47 | starseeker | opps |
| 18:41.16 | yukonbob | nice |
| 18:41.45 | starseeker | So this morning I decided I'd give it a go, and one thing sorta led to another... |
| 18:42.35 | brlcad | did you get internal texture working or is that external? |
| 18:44.23 | starseeker | external |
| 18:44.57 | starseeker | it's actually pretty simple - a texture shader for the external sphere, then the rest as basic shapes |
| 18:46.40 | starseeker | yikes |
| 18:48.02 | yukonbob | starseeker: what images are you using? |

| 18:57.19 | Z80-Boy | When I run "mged" it says backgrounding or initializing or something like that and waits for a long time |
| 18:57.25 | Z80-Boy | then it returns with "Detached" |

| 18:57.35 | Z80-Boy | no mged process is running afterwards |
| 18:57.42 | brlcad | how'd you install it? |
| 18:57.50 | Z80-Boy | During the wait, one there is one mged process and one mged [defunct] process |
| 18:57.57 | Z80-Boy | ./configure --prefix=/usr; make; make install |
| 18:58.09 | brlcad | ah |

| 19:01.26 | Z80-Boy | isn't it freetype or fontconfig or something like that? |
| 19:01.41 | louipc | that's why the default configure; make; make install installs in /usr/brlcad |
| 19:02.14 | louipc | Z80-Boy: I think it's some kernel stuff too |

| 19:02.42 | louipc | lol |
| 19:03.08 | starseeker | Z80-Boy: This is experience talking. If you're on Linux, the odds are good that the answer is yes |
| 19:03.15 | louipc | why would you convert that to png? |
| 19:03.26 | starseeker | To convert it to pix, to use it as a texture |
| 19:03.31 | Z80-Boy | Linux comes pre-borked by design |
| 19:03.46 | louipc | no support for jpg textures? |
| 19:03.47 | louipc | gah! |
| 19:04.15 | Z80-Boy | it's not a matter of RAM, but a matter of well written program |
| 19:04.18 | louipc | Z80-Boy: how's that? |
| 19:05.01 | Z80-Boy | You can do conversion without placing the whole image into the memory |
| 19:05.28 | louipc | i mean how is linux pre-borked? |
| 19:06.36 | starseeker | Well, so far the Gimp is thrashing and Imagemagick's convert refused to try |
| 19:06.44 | starseeker | what else 'ya got? |
| 19:08.59 | Z80-Boy | what is the source format of the image? |

| 19:09.22 | Z80-Boy | how much tile cache do you have in GIMP? |
| 19:09.27 | Z80-Boy | What are the dimensions of the jpeg? |
| 19:09.41 | brlcad | Z80-Boy: possibly.. |
| 19:09.45 | Z80-Boy | Imagemagick is a piece of crap, very suboptimal |
| 19:09.48 | brlcad | that is why it's not the default |

| 19:11.10 | starseeker | 1 gig |
| 19:11.11 | brlcad | Z80-Boy: the issue really depends on your system .. if you had the deprecated librt.so installed and in use, you'll have problems (as we have a librt) |
| 19:11.32 | brlcad | another common one is libbu and libbn .. but those are much more rare |
| 19:12.40 | brlcad | louipc: no support for any lossy formats |
| 19:13.15 | Z80-Boy | starseeker: to convert this image into png, you need 518400 bytes of memory |
| 19:13.22 | Z80-Boy | a strip 21600 pixels wide and 8 pixels high |
| 19:15.05 | starseeker | Hang on - looks like I might be able to use some old fashioned tools and make a pit stop in pnm... |
| 19:15.48 | Z80-Boy | lol |
| 19:15.55 | starseeker | bingo |
| 19:15.56 | Z80-Boy | you need a lot of disk space for that I guess |
| 19:17.14 | starseeker | Yep - if the other tools were trying to do that in memory no wonder it crapped out |
| 19:18.57 | starseeker | Heh - cool - the pnm and the pix formats are almost exactly the same - pnm VERY slightly bigger |

| 22:34.23 | starseeker | meh - even the high resolution map doesn't have NEARLY enough detail |
| 22:55.21 | brlcad | starseeker: you can go into object/solid selection mode which will illuminate objects -- hit 's' or 'o' in the graphics window and move the mouse up/down |
| 22:55.26 | brlcad | it'll illuminate and tell you the name |
| 22:55.34 | brlcad | hit q or esc to cancel |
| 22:55.50 | brlcad | (otherwise it effective does an oed or sed) |
| 22:55.54 | starseeker | OK. Yeah, that's how I had been doing it |
| 22:56.29 | starseeker | Not a very normal problem for this type of software anyway ;-) |
| 22:56.56 | brlcad | what do you mean? |
| 22:57.36 | brlcad | or is it just something so small that even illuminated it's not clear what/where it is? |
| 22:57.49 | starseeker | zooming from something 6000km across to something a couple meters long |
| 22:58.00 | starseeker | basically |
| 22:58.13 | starseeker | the eyepoint and lookat settings did the trick |
| 22:58.31 | brlcad | center work similar to lookat as well |
| 22:59.10 | brlcad | or if you autoview one object and then e up additional objects, it won't change the display size |
| 22:59.21 | brlcad | e.g. B up something tiny, then e up the big thing |
| 22:59.28 | starseeker | Ah |
| 22:59.37 | starseeker | That would do it |
| 23:00.03 | starseeker | No biggie - even the really high resolution photo didn't have nearly enough detail for the shot I was trying to line up |
| 23:00.23 | brlcad | ahh |
| 23:01.48 | starseeker | This is kinda cool: http://my.bzflag.bz/~starseeker/earth-night.png |
| 23:03.20 | brlcad | yeah, that is |
| 23:03.51 | starseeker | Nothing you couldn't do with any sphere mapping software of course |
| 23:04.55 | brlcad | yeah, nothing special, but still pretty cool ;) |
| 23:05.01 | brlcad | you can do some other effects |
| 23:05.11 | brlcad | is that just the texture shader or stacked with phong? |
| 23:05.19 | starseeker | texture shader |
| 23:05.39 | brlcad | try the "stack" shader, and add texture and glass |
| 23:06.07 | brlcad | or texture and bumpmap.. that might be neat |
| 23:10.57 | starseeker | What should I see on bumpmap? |
| 23:11.11 | brlcad | good question :) |
| 23:11.14 | brlcad | depends on the bump map |
| 23:11.33 | starseeker | Do I enter the bump map first or the texture first? |
| 23:12.44 | brlcad | bump mapping in general fakes the impression of surface detail |
| 23:12.46 | brlcad | I'd think the texture is first |
| 23:13.11 | brlcad | adding glass or plastic on top should make it look like it's painted/glossy |
| 23:13.54 | brlcad | nasa has some topological maps, those would probably work even better, but you should get something from just using the same image as a bump map too |
| 23:15.30 | starseeker | Glass killed it somehow |
| 23:15.44 | brlcad | huh? |
| 23:15.51 | brlcad | killed as in crashed? |
| 23:15.55 | starseeker | just getting speckles |
| 23:16.04 | brlcad | hm |
| 23:16.05 | brlcad | ahh |
| 23:16.20 | brlcad | yeah, maybe not glass, it's going to let most of the light through |
| 23:16.32 | brlcad | plastic probably better |
| 23:20.24 | starseeker | hmm - http://my.bzflag.bz/~starseeker/weird1.png |
| 23:21.05 | starseeker | it's interesting, that's for sure... |
| 23:21.23 | starseeker | stack {{texture {file world4.pix w 21600 n 10800}} {bump {file world4.pix w 21800 n 10600}} {plastic {}}} |
| 23:22.50 | brlcad | any reason the file dimensions are different? :) |
| 23:22.59 | starseeker | ooops |
| 23:23.26 | brlcad | it's not an ideal bump map either, so it may still look wonky |
| 23:24.00 | brlcad | usually it's a greyscale indicating depth |
| 23:24.14 | brlcad | heck, it may even be assuming bw instead of pix |
| 23:24.39 | starseeker | could be |
| 23:25.12 | starseeker | Yeah, that's better - not much in the way of bumpmapping though |
| 23:25.25 | starseeker | bbl, gotta put away dishes |
| 23:25.58 | brlcad | I'd imagine at that scale, you'd have to increase the bump size considerably too |

| 23:50.02 | starseeker | brlcad: technically, any bumpmapping that would have anything like visual significance on this scale probably wouldn't be physical anyway ;-) |
| 23:57.21 | starseeker | ah, shoot - the mapping of the image isn't corresponding to the physical dimensions I had laid out |
