00:39.34 Nohla this
00:45.05 starseeker interlay puts the wireframe under the raytrace image, but keeps the faceplate gui on top
00:45.47 starseeker To see this - check both Faceplate and Faceplate GUI under Misc in the MGED window
00:46.06 starseeker Then bring up the raytrace control panel, do a raytrace, and enable the framebuffer
00:46.32 starseeker Try switching between underlay, interlay and overlay
00:52.25 starseeker does that help?
00:52.50 Nohla yes :)
00:53.05 starseeker interlay isn't used as commonly as the other modes
00:54.16 starseeker situations where you want both a framebuffer view and the faceplate GUI are fairly rare
00:55.32 starseeker any luck getting set up for committing?
00:59.06 starseeker Nohla: if your login is fixed, committing is simple
01:00.02 Nohla login in SF?

03:01.42 Nohla buuu
03:05.57 Nohla well, is anybody out there? I've a simple question about a word.
03:06.06 louipc hi

03:09.42 *** join/#brlcad jesica__ (n=jesica@168.226.176.181)
03:09.53 jesica__ sorry I'm back
03:10.11 jesica__ I'm trying to translate blast command
03:10.24 jesica__ literally blast is like blow up
03:10.52 jesica__ but its function remaind me the word refresh more than explode
03:11.50 jesica__ *remind
03:12.18 louipc hmm I'm not sure what the command's name comes from
03:12.50 jesica__ blast replace both, Z and Draw command
03:12.52 louipc it reminds me more of etch-a-sketch
03:13.17 louipc you know that toy with the two dials that you draw with
03:13.32 louipc if you shake it everything is erased and you can draw again
03:14.21 jesica__ well, but it clears the grafic window and redraw the last parametres
03:14.33 jesica__ It's not the same, I think
03:14.46 brlcad hey jesica__
03:14.46 ``Erik the 'b' blast command?
03:14.51 jesica__ yes
03:14.52 brlcad B is blast
03:15.04 jesica__ ah?
03:15.07 ``Erik it sets the display list to the specified item (removing everything that used to be in it)
03:15.32 brlcad B == Z + e
03:15.38 louipc why's it called blast?
03:15.46 ``Erik cuz it's both barrels, baybee
03:15.56 brlcad Z is zap
03:16.16 jesica__ brlcad I know, but I can see why it's called blast
03:16.31 brlcad jesica__: can or cannot?
03:16.40 jesica__ can't :)
03:17.05 brlcad because it's derived from "zap" ... but does more
03:17.27 jesica__ ?
03:17.50 louipc i'll zap you with my laser cannon
03:17.52 ``Erik mostly colloquialisms... :)
03:18.02 louipc I mean blast you with my laser cannon
03:18.54 brlcad hm, que significa zap.. que es lo que pasa cuando tocas una amiga y te pasa una pequen~a electrificacion? .. en ingles, se dice que el sonido es un "zap"
03:18.54 jesica__ but blast doesn't draw again
03:19.08 brlcad "B something"
03:19.11 jesica__ tocas a una amiga???JAJAJAJA
03:19.23 jesica__ aaaah tocar de tocar!
03:19.23 brlcad no asi .. :P
03:19.23 ``Erik blast will draw only what's specified, it sets the display list
03:19.26 jesica__ XD
03:20.16 brlcad electricidad est?tica causa un sonido "zap"
03:20.39 jesica__ brlcad do you know the synonymous of blast, in spanish?
03:20.43 brlcad blast es como una explosion, mas grande :)
03:21.00 jesica__ una explosion redibuja?
03:21.05 brlcad ra'faga?
03:21.22 jesica__ busqu? su traduccion literal
03:21.46 jesica__ me confunde que sea Z y draw
03:22.13 brlcad "B algo" == "Z + e algo"
03:22.21 jesica__ sorry, we shouldn't write spanish :P
03:22.43 brlcad oh, and "e" is "draw"
03:22.49 brlcad they mean the exact same thing
03:23.03 brlcad I'm just used to the old short name
03:23.29 brlcad 'draw' is the newer name for the command, what everyone should be using
03:23.53 jesica__ The Blast command is shorthand for the combination of the Z and draw
03:23.53 jesica__ commands.
03:24.08 ``Erik if spanish improves communication to aid in translating, then why not? :) I'll just sit here and imagine you were talking about commodores and tacos :D *duck*
03:24.11 jesica__ that says the lesson
03:24.27 brlcad jesica, do you know what transparency paper is?
03:24.46 jesica__ yes
03:25.40 brlcad if you have two pieces of transparency paper, those are like the framebuffer and the graphics window .. overlay/interlay/underlay is how those two sheets interact
03:26.17 Nohla ah?...
03:26.27 brlcad overlay, the framebuffer sheet is on top; underlay, the framebuffer sheet is underneath .. and interlay is a little more complicated but they basically go through each other
03:27.20 Nohla you can see both at the same time?
03:27.28 Nohla no...
03:28.03 Nohla if they're transparencies you can with overlay and underlay too
03:28.10 Nohla doesn't it?
03:29.56 brlcad you can see both
03:30.01 brlcad until you draw on them
03:30.10 brlcad then whichever is on top will show
03:30.46 brlcad so if you are overlay and have raytraced, you will not see the wireframe.. because the raytrace is drawn to the framebuffer (which is on top)
03:31.21 brlcad if you switch it to underlay, the framebuffer will be underneath and you'll see both the wireframe and the raytrace
03:35.19 Nohla until I draw on then too
03:35.22 *** join/#brlcad Desert69 (n=Desert69@190.48.220.225)
03:36.14 Nohla brlcad we left blast :P
03:36.45 brlcad right, until you draw on the graphics window too.. but those are a LOT harder to fill :)
03:37.29 brlcad which is a pretty useless wireframe if it has that many edges :)
03:38.15 Nohla and interlay bring both views?
03:38.25 Nohla even if you draw on it?
03:39.28 Nohla buuu hard to put it in my head :P
03:39.37 brlcad interlay depends on the depth of objects in the graphics window.. it is more like a cube and the framebuffer slices through it
03:39.57 brlcad it's easier to understand when you run mged and see it in action
03:40.14 Nohla so I should
03:41.54 Nohla well, brlcad sorry if I'm boring with it
03:42.16 Nohla but I still cannot understand how blast can build a draw
03:42.33 Nohla at least, it's an explosion :)
03:46.28 brlcad Nohla: heh, you're not boring :P
03:46.44 brlcad nobody claimed that blast was a good name :)
03:47.19 brlcad technically it's just the "B" command, but it was derived from zap so it was called blast
03:47.23 louipc it sounds like it's a blast
03:47.45 brlcad very punny
03:47.48 Nohla no :)
03:47.53 Nohla I dont think that
03:48.40 Nohla blast = zap ?
03:49.55 Nohla such a pun!
03:50.46 Nohla well, I've done worse thing with marijuana :)
03:51.16 brlcad heh
03:51.55 Nohla brlcad any suggestion to translate it?
03:52.10 brlcad "sounds like it's a blast" contains a pun on blast -- there it means "sounds like it's a lot of fun"
03:52.20 Nohla just to bring and idea for some pleople who don't know a word in english
03:52.39 brlcad call it the "B" command :)
03:52.54 brlcad borrar y dibujar
03:53.10 Nohla isn't it like refresh?
03:53.16 brlcad no
03:53.27 Desert69 redraw? :)
03:53.31 Nohla it zap and write? or zap and let it ready to be drawn?
03:53.38 Desert69 (hi there! :) )
03:53.59 brlcad it's only a redraw if you B the same object(s) you were already looking at
03:54.10 brlcad but you can erase and draw anything
03:54.48 Nohla well, I'll do this: explain what B does, and since then, i'll just call it B command
03:54.50 *** join/#brlcad akafubu (n=akafubu@unaffiliated/akafubu)
03:54.56 Nohla do you like it?
03:55.08 brlcad sounds great
03:55.24 brlcad you could say "Borrar y dibujar"
03:55.33 brlcad that fits
03:55.54 Nohla its not the same that zap and let it ready to draw
03:56.00 Nohla isn't it?
03:56.14 brlcad no entiendo
03:56.38 Nohla it zap and write? or zap and let it ready to be drawn?
03:56.46 brlcad "B object" is exactly equal to "Z" followed by "draw object"
03:56.54 Desert69 it **do** draws every object you were looking at, right?
03:57.19 Nohla brlcad ah ok
03:57.21 brlcad no, Desert69 .. it draws whaever object(s) you list after B
03:57.30 brlcad draw a b c
03:57.31 brlcad Z
03:57.43 brlcad [that erases a b c]
03:57.48 Desert69 apsss ok... got it :)
03:57.49 Nohla loud and clear :)
03:57.49 brlcad draw a b c
03:57.58 brlcad B a d e f
03:58.09 brlcad [that erases a b c, then draws a d e f]
03:58.30 brlcad would have been the same as
03:58.33 brlcad Z
03:58.35 brlcad draw a d e f
03:58.40 brlcad instead it's just
03:58.41 brlcad B a d e f
03:59.11 brlcad minor efficiency, but pretty important when you do that hundreds of time in one day
04:00.55 Nohla brlcad I'll finish 4th and 5th tomorrow
04:01.25 Nohla and starseeker will help me and show me something he announced yesterday
04:01.59 Nohla (maybe you know what)
04:02.08 starseeker Nohla: I announced something?
04:02.40 Nohla starseeker I was not in that moment, but read it before
04:02.46 Nohla let me look for it
04:04.14 Nohla well, I don't know
04:05.17 Nohla It was something like you changed (don't know what) and will show me how to do it now
04:05.30 Nohla with that change
04:05.35 starseeker uh
04:05.54 Nohla sorry, I was too tired when I read it
04:06.05 starseeker if your sourceforge account is ready, I can walk you through doing the commit of the two new translations yourself
04:06.24 Nohla ok, we will
04:06.37 Nohla (tomorrow, you know)
04:06.41 starseeker brlcad: she does have commit access, yes?
04:06.52 starseeker to at least doc/docbook?
04:07.04 Nohla starseeker I think I do
04:07.12 starseeker ok, cool :-)
