| 04:59 | | * Zed needs a really smart person who knows the answer to his computer-build problem |
| 05:00 | <@Vornicus> | Just Ask |
| 05:00 | < Zed> | I have a ... lemme get names |
| 05:01 | < Zed> | MSI K9A2 motherboard |
| 05:01 | < Zed> | I was running on it, recently, using a phenom X3 720 BE |
| 05:02 | < Zed> | Then I gave the mobo to my little brother along with my OLD old proc (an athlon 64 3200) and upgraded to another MSI board, an AM3 board which works just fine |
| 05:02 | < Zed> | I then upgraded to a phenom II x6, which works great on my am3 board |
| 05:03 | < Zed> | But when I tried to put the x3 720 back into Nik's computer, it's not working |
| 05:04 | <@Namegduf> | Hmm. |
| 05:04 | < Zed> | which made me think it might be dead, so I had a friend test it in his new mobo, which worked fine |
| 05:04 | <@Namegduf> | No idea. |
| 05:04 | < Zed> | So I thought I might have damaged the mobo, so I tried it with the old proc |
| 05:04 | < Zed> | worked fine. |
| 05:04 | < Zed> | Thought the power might have been insufficient, so I tried it with my power supply, and had no luck |
| 05:04 | < simon_> | hmm |
| 05:04 | < simon_> | the C++ standard says: |
| 05:04 | < Zed> | memory was working fine on the old chip, but I thought about switching to a single dimm and trying in different slots, with no luck |
| 05:05 | < simon_> | hexadecimal-escape-sequence: |
| 05:05 | < simon_> | \x hexadecimal-digit |
| 05:05 | < simon_> | hexadecimal-escape-sequence hexadecimal-digit |
| 05:05 | < Zed> | I tried flashing the BIOS on the mobo, which shouldn't fix it, cuz it had been running fine on it before, but it didn't help, either |
| 05:06 | < Zed> | I'm just coming up kinda blank. |
| 05:06 | < simon_> | oh, wait, never mind! |
| 05:06 | < Zed> | So I'm totally clueless. |
| 05:06 | < Zed> | I've got no answers, but the problem just doesn't make sense |
| 05:07 | < Zed> | all the pieces WERE compatible with each other, and now they don't work when assembled together |
| 05:07 | < Zed> | They all test out as working just fine when put into other setups, though. |
| 05:08 | < simon_> | yes, one question: does that mean that \xBE \xEF is a valid escape sequence? |
| 05:10 | | * simon_ tries. |
| 05:10 | < Zed> | I'm just at a loss as to what to TEST next. |
| 05:10 | < Zed> | Is it, simon? |
| 05:12 | < simon_> | Zed, don't new mobos have those LED displays that tell you what might be wrong? |
| 05:12 | < Zed> | Not a new-new board. |
| 05:12 | < Zed> | It's a generation old, after all |
| 05:12 | < simon_> | and it doesn't make any funny beeps that one can decipher, either? |
| 05:13 | < Zed> | It's not giving me any POST beeps when it has the phenom II in it |
| 05:13 | < Zed> | and it works just fine when it has the other proc in it |
| 05:13 | < simon_> | is that a graphics card? |
| 05:13 | < Zed> | Which would be definitive "it just doesn't work" except it DID |
| 05:13 | < Zed> | Phenom II? |
| 05:13 | < simon_> | yes? |
| 05:13 | < Zed> | nah, it's an AMD cpu |
| 05:14 | < simon_> | did you test whether it's the CPU chip that doesn't work? you only mentioned that a friend tested the mobo, right? |
| 05:29 | < Zed> | No, the proc was tested in their mobo |
| 05:29 | < Zed> | came up just fine |
| 05:30 | < Zed> | I ran on it myself earlier that day, too |
| 05:30 | < Zed> | like, all diagnostic steps point to the proc - except the part where it works fine. |
| 05:31 | < Zed> | Then all diagnostic steps point to it just not being compatible with that setup |
| 05:31 | < Zed> | except that it was IN that exact setup |
| 05:31 | < Zed> | same vid card, same memory, same mobo, same proc, and the PSU has been tested with one that's known working with much higher load equipment, AND all the parts work fine with the other proc. |
| 05:32 | < Zed> | BIOS flash should not have been necessary, but it's been tried anyways |
| 05:32 | < Zed> | What I need is an idea on setting it up better |
| 05:32 | < Zed> | like, a way to install it more ... something-y. |
| 05:32 | < Zed> | ly, I should say |
| 05:32 | < Zed> | adverbially speaking |

| 18:24 | < Derakon[irssi]> | I don't get why they want to block IRC in the first place. |

| 19:51 | < Derakon[irssi]> | The framebuffers are upside-down! |
| 19:51 | < Derakon[irssi]> | (I figured this out by labeling each individual tile) |
| 19:53 | < Derakon[irssi]> | Now, *why* are they upside-down? |
| 19:56 | < Derakon[irssi]> | Unrelated: Child's Play opened today and is already almost at $200k. |
| 19:57 | < gnolam> | There was a bit too much unrelated code in that for me to put in the effort to decode, unfortunately. |

| 21:38 | < Derakon[irssi]> | Okay, so, only the framebuffer that is positioned at (0, 0) is getting drawn to correctly... |
| 21:39 | < Derakon[irssi]> | I'd guess this means I need to toss a translate in or something? |
| 21:40 | < Derakon[irssi]> | I want to partition the entire view area into a 2x2 grid of tiles, then render content to them. |
| 21:40 | < Derakon[irssi]> | So I do glViewport(i * self.width / 2, j * self.height / 2, self.width / 2, self.height / 2) |
| 21:41 | < Derakon[irssi]> | Then glScalef(2, 2, 1) |
| 21:41 | < Derakon[irssi]> | Then I just draw everything for that part of the view. |
| 21:42 | < Derakon[irssi]> | This works fine for the tile at (0, 0) but the other tiles don't show what is rendered to them; they're just white (the fill color). |
| 22:20 | < gnolam> | Be careful with scaling. It's so easy to overlook a translation somewhere. |
| 22:28 | < gnolam> | (Also, it scales normals, but I guess you don't have to worry about those.) |
| 22:32 | < Derakon[irssi]> | Oh, dur. I should add a translate to compensate. |
| 22:32 | < Derakon[irssi]> | And yeah, this is strictly 2D. Thanks. |
| 22:35 | | * gnolam headdesks. |
| 22:39 | < Derakon[irssi]> | Gah, I suck at visualizing this stuff. |

| 22:39 | < gnolam> | My looping sounds didn't stop looping properly. After dissecting my own loop stopping code and the Sound Envelope Controller, it turns out that the culprit was a misplaced if in the loop /starting/ function. :P |
| 22:39 | < Derakon[irssi]> | Exactly where you'd look when it doesn't stop properly, naturally. |
| 22:40 | < gnolam> | The whole "should I stop this loop now and switch to another one?" bit was quite cleverly bypassed in favor of KEEP PLAYING NO MATTER WHAT. :P |
| 22:41 | | RichardBarrell [mycatverbs@Nightstar-689c9c54.cable.virginmedia.com] has joined #code |
| 22:48 | < Derakon[irssi]> | So, problem I'm trying to solve is that I have e.g. a 10000x10000 canvas with lots of textured quads in it, and I want to render that canvas from a distance without lagging. Therefore I pre-render the quads to other quads at a fixed level of zoom, packing multiple of the distant quads into each close quad. |
| 22:48 | < Derakon[irssi]> | Here's the code where I render to a close quad: http://paste.ubuntu.com/532644/ |
| 22:49 | < Derakon[irssi]> | Gnolam's almost certainly right that I need a glTranslate call in there somewhere, but I can't for the life of me visualize the setup and figure out where it should go. |
| 22:50 | < Derakon[irssi]> | There are NUMTILESxNUMTILES prerendered quads, with i and j iterating over them. |
| 22:52 | < Derakon[irssi]> | When drawing normal (non-prerendered) quads I do glScalef(ZOOM, ZOOM, 1); here I use a lesser zoom...wait, am I using the proper zoom here? |
| 22:52 | < Derakon[irssi]> | ...yeah, because when I draw I do get one prerendered quad to show (the one at (0, 0)) and it has the right scale. |
| 22:56 | | RichardBarrell [mycatverbs@Nightstar-689c9c54.cable.virginmedia.com] has quit [Connection closed] |
| 23:11 | < gnolam> | The whole glViewporting is a bit iffy as well. |
| 23:12 | < Derakon[irssi]> | Yeah, I'm not entirely clear how that relates to the scene. |
| 23:12 | < gnolam> | Where does i and j come from? |
| 23:12 | < Derakon[irssi]> | They're iterating over the prerendered textures. |
| 23:12 | < Derakon[irssi]> | So they range from 0 to NUMTILES - 1, each. |
| 23:14 | < gnolam> | And the framebuffer is supposed to do what exactly? |
| 23:15 | < Derakon[irssi]> | Prerender hundreds of textures that are each shown at a low resolution, so I can just draw the one texture when it comes to actually showing things. |
| 23:15 | < Derakon[irssi]> | I have a massive canvas that shows thousands of 512x512 textures, but they're downscaled so they only use maybe 64x64 of actual screen real estate. |
| 23:16 | < Derakon[irssi]> | The costs of rendering all of those textures each frame make the app very unresponsive. |
| 23:16 | < Derakon[irssi]> | So I figured I could prerender them to a single texture. |
| 23:17 | < gnolam> | All of them to a single FBO? |
| 23:17 | < Derakon[irssi]> | I only have one framebuffer that I re-use for each of the prerendered textures. |
| 23:17 | < Derakon[irssi]> | That's self.buffer. |
| 23:18 | < Derakon[irssi]> | Which I note isn't referred to in this code. Hm. |
| 23:19 | < Derakon[irssi]> | Anyway, target in this case is the texture being rendered to. |
| 23:19 | < Derakon[irssi]> | It is (self.canvasWidth / NUMTILES) x (self.canvasHeight / NUMTILES) in size. |
| 23:28 | < gnolam> | ... which would make the viewport go outside that at any i or j > 0. |
| 23:29 | < gnolam> | Or did you mean tiles? |
| 23:31 | < gnolam> | *in size |
| 23:31 | < Derakon[irssi]> | NUMTILES is 2 here, and canvasWidth = canvasHeight = 7000. |
| 23:31 | < Derakon[irssi]> | Thus each prerendered tile (mini-canvas?) is 3500x3500. |
| 23:32 | < Derakon[irssi]> | self.width = self.height = 700px, i.e. on-screen the entire thing is rendered into a 700x700 window. |

| 23:35 | < Derakon[irssi]> | Hey hey hey! I think this is what I want! |
| 23:35 | < Derakon[irssi]> | Switched the glViewport to start at (0, 0) and added a translate after the scale. |
