| 21:01.56 | KaadmY | where's the ground drawn in the main menu? |
| 21:02.12 | KaadmY | (trying to draw a tank model in the menu background) |
| 21:06.08 | KaadmY | and what would be the best place to put that? |
| 21:06.40 | KaadmY | any way to find out if you're playing? could just render a tank in src/bzflag/BackgroundRenderer.cxx when not playing actually |
| 21:12.33 | KaadmY | woah |
| 21:12.52 | KaadmY | rendering a tank(with in-game effects, ie. shadows/lighting) is pretty difficult |
| 21:13.09 | KaadmY | and i can't seem to find where the background is rendered, either |
| 21:13.27 | blast007 | BackgroundRenderer.cxx ? |
| 21:13.37 | blast007 | :P |
| 21:13.48 | KaadmY | <KaadmY> any way to find out if you're playing? could just render a tank in src/bzflag/BackgroundRenderer.cxx when not playing actually |
| 21:13.57 | KaadmY | ik i can change that file |
| 21:14.10 | KaadmY | but i have no idea how the entire scene node/rendering setup works |
| 21:14.14 | KaadmY | ie. shadows, lighting |
| 21:14.29 | blast007 | "i can't seem to find where the background is rendered" so why wouldn't that be in BackgroundRenderer.cxx? that renders the ground and sky. |
| 21:14.32 | KaadmY | or where the main menu world is generated |
| 21:14.39 | KaadmY | yes |
| 21:14.49 | KaadmY | but where are the render functions called from? |
| 21:14.50 | blast007 | and lots of other bits too, it seems |
| 21:15.00 | blast007 | set a breakpoint in there and look at the call stack |
| 21:15.15 | blast007 | (in your debugger) |
| 21:16.07 | JeffM | when you arn't connected it should just call the renderer with an empty world. |
| 21:16.15 | JeffM | because the menu draws on top of the playing world too |
| 21:16.17 | KaadmY | JeffM: any idea where the world is created? |
| 21:16.23 | KaadmY | the main menu world? |
| 21:16.25 | JeffM | so background renderer shold be called. |
| 21:16.33 | JeffM | there is NO world |
| 21:16.39 | JeffM | the ground is not part of the world |
| 21:16.43 | JeffM | nor is the sky |
| 21:16.47 | KaadmY | ah |
| 21:16.51 | blast007 | use your debugger |
| 21:16.55 | JeffM | those are always drawn |
| 21:17.10 | JeffM | yeah use a friggin debugger and see that it steps into background renderer |
| 21:17.23 | JeffM | then make it draw a tank when the server is disconected |
| 21:17.47 | JeffM | you don't want "in menu" because you can be in menu and on a real map and you don't want to modify that map |
| 21:18.19 | KaadmY | JeffM: yes |
| 21:23.27 | JeffM | yes to the debugger? :) |
| 21:23.40 | JeffM | seriously, just get it setup. |
| 21:23.56 | JeffM | or get a GUI for it |
| 21:24.01 | JeffM | if you don't like GDB |
| 21:26.26 | blast007 | Install QT Creator. It supports autotools projects like ours. |
| 21:28.21 | KaadmY | so from looking through the code, i think just instancing "Player" and rendering in the menu will work? |
| 21:28.24 | blast007 | but do make sure to run BZFlag windowed when you do |
| 21:28.31 | KaadmY | are there problems with that? |
| 21:28.38 | KaadmY | i always run bz windowed |
| 21:28.52 | blast007 | and with mouse grabbing completely disabled |
| 21:28.56 | KaadmY | ie. not bzflag's fullscreen, i use i3's builtin fullscreen tho |
| 21:29.30 | KaadmY | i can't just create a player and put it in the player list |
| 21:29.44 | JeffM | blast007: did you keep or disable Win32NoMin? |
| 21:29.56 | KaadmY | because there's multiple places that check for the tank's existence to see if you're connected to a server |
| 21:30.03 | JeffM | KaadmY: get 3 displays, it's much nicer :) |
| 21:30.17 | blast007 | JeffM: doesn't seem like we minimize on defocus with SDL2 |
| 21:30.20 | JeffM | KaadmY: don't create a localPlayer, just call the drawing code |
| 21:30.53 | JeffM | blast007: ok, good. the code that did that on win32 was done on purpose, it doesn't have to minimize. Chris just wanted it to do that |
| 21:30.55 | JeffM | so I did that |
| 21:31.01 | JeffM | made debugging a pain tho |
| 21:31.06 | KaadmY | JeffM: do the rendering calls correctly call the shadows/lighting code? |
| 21:31.15 | blast007 | the window is resizable now too |
| 21:32.05 | JeffM | KaadmY: lighting is part of GL. for shadws there is a shadow render node, you can call both. |
| 21:32.18 | JeffM | are shadows still a hack? |
| 21:33.01 | blast007 | I don't recall any changes to shadows, so if it was a hack before, it's still a hack |
| 21:33.04 | JeffM | once you have a debugger, you can step into the code that draws player tanks and see what is called. then jsut call those same functions with out a player object. |
| 21:33.27 | JeffM | the last change was a blending change, it looked better but was not volumetric IIRC |
| 21:33.49 | blast007 | shadows still only apply to the ground, afaik |
| 21:34.00 | blast007 | show on the ground, I mean |
| 21:34.02 | JeffM | yeah, that's just a plane projection of the geometry then |
| 21:34.09 | JeffM | yeah I know what you mean |
| 21:34.43 | JeffM | the geometry of the tank is flattened along a viewpoint from the sun, then just draw as a bunch of flat polygons just above the ground plane |
| 21:34.51 | JeffM | with a blend mode that doesn't make it overlap |
| 21:36.59 | JeffM | projectng that geometry onto a shape is harder |
| 21:37.27 | JeffM | rending that shape to a texture buffer then projecting that texture into the world could be made to work in the GL 1.1 world |
| 21:43.02 | KaadmY | why is gl 1.1 still supported? |
| 21:43.12 | KaadmY | is there any need for 1.1 support still? |
| 21:45.35 | blast007 | that is the version we currently target |
| 21:48.50 | blast007 | we won't be changing the requirement in the 2.4 branch |
| 21:52.16 | KaadmY | yay |
| 21:52.19 | KaadmY | we got a tank model |
| 21:52.23 | KaadmY | except it's translucent |
| 21:52.24 | KaadmY | must fix |
| 21:58.16 | KaadmY | huzzah |
| 21:58.20 | KaadmY | tank drawing :P |
| 22:04.33 | JeffM | KaadmY: because it has to run on a SGI computer from 1995 |
| 22:05.11 | KaadmY | JeffM: this is 2016 |
| 22:05.24 | KaadmY | hasn't ogl 1.1 been pretty much dead for years now? |
| 22:05.33 | JeffM | what does that have to do with bzflag? |
| 22:05.40 | KaadmY | not much |
| 22:05.46 | JeffM | all drivers still support GL 1 and 1.1 |
| 22:06.15 | KaadmY | and nearly all drivers support 2.1 |
| 22:06.29 | JeffM | not on a SGI machine from 1995 ;) |
| 22:06.42 | blast007 | KaadmY: not even your GPU supports GL 2.1 |
| 22:06.46 | blast007 | yours supports 1.5 |
| 22:06.58 | JeffM | yeah he's got no shaders |
| 22:07.03 | KaadmY | blast007: it can *run* 2.1 |
| 22:07.07 | KaadmY | probably mesa tho |
| 22:07.13 | JeffM | so slowness |
| 22:07.15 | KaadmY | not surprised HW's 1.5 |
| 22:07.28 | blast007 | my XP laptop only does 1.1 |

| 22:10.18 | KaadmY | where's the gl viewport aligned to the cockpit? |
| 22:10.38 | KaadmY | btw ground vehicles tend to use the term "cab" |
| 22:10.38 | JeffM | wiht the modelview matrix |
| 22:10.39 | blast007 | his seems to have shader model 3 |
| 22:10.46 | KaadmY | me? |
| 22:11.01 | blast007 | yes you |
| 22:11.15 | JeffM | look for a GL Push, |
| 22:11.17 | KaadmY | glsl 120, not sure what v3 is |
| 22:11.21 | blast007 | unless JeffM was referring to mine |
| 22:11.26 | JeffM | it'll be before it pops and goes ortho |
| 22:11.34 | blast007 | mine definitely doesn't have teh shaders |
