| 00:00.15 | mastergoon | nice |
| 00:00.39 | mastergoon | getting sockets working right can be hard |
| 00:00.47 | mastergoon | had many struggles getting them to work on my game lol |
| 00:18.00 | mackstann | netxx library for c++ looks neat |
| 00:18.04 | mackstann | for network stuff |
| 00:19.06 | mastergoon | never heard of it, will have to take a look |
| 00:20.30 | hyriand | oh.. before I forget.. |
| 00:20.48 | hyriand | there's a philosophical off-by-1-pixel error in awidgets |
| 00:21.50 | brailsmt | ooh, philosophy |
| 00:21.53 | brailsmt | :) |
| 00:21.56 | hyriand | I assume "right = left + width" everywhere |
| 00:22.18 | hyriand | but.. it's supposed to be "right = left + width - 1" |
| 00:22.37 | hyriand | so that left == right if the width is 1 |

| 00:25.23 | hyriand | the problem is how one looks at a rectangle on a dimensional plane that has only pixels instead of 'real' dimensions |
| 00:26.56 | hyriand | in a mathematical vision, left == right would mean the rectangle has no width |
| 00:27.12 | hyriand | but it seems, digital science thinks otherwise |
| 00:28.18 | hyriand | (or am I not making any sense at all here?) |
| 00:28.58 | mackstann | -1 seems wrong to me |
| 00:29.13 | brailsmt | hyriand: no you are, it makes sense too |
| 00:29.16 | mackstann | if there is width, then there is a difference between left and right, and they should not be equal |
| 00:29.46 | mackstann | the index of the pixel is its left edge, if that makes any sense |
| 00:29.47 | brailsmt | mastergoon: but with only one pixel, left and right are the same |
| 00:30.14 | mackstann | brailsmt: think about a box, or something real |
| 00:30.21 | mackstann | that's definitely not the case |
| 00:30.25 | brailsmt | mackstann: a pixel isn't real |
| 00:30.31 | hyriand | mackstann: 'real' world things don't apply since their precision is infinite |
| 00:30.35 | brailsmt | we are talking strictly pixels |
| 00:30.37 | hyriand | and a pixel is a pixel |
| 00:30.41 | mackstann | but it works with a number line, like anything else, doesn't it? |
| 00:30.43 | hyriand | yeah, what brailsmt says |
| 00:30.47 | brailsmt | not real life stuff |
| 00:31.01 | mackstann | what makes pixels different? it's all numbers |
| 00:31.21 | brailsmt | and even if we were talking about real life things... ever hear of quantum mechanics... :) |
| 00:31.23 | hyriand | no it's not.. you can divide a meter into centimeters.. |
| 00:31.44 | hyriand | you can't really splice a pixel |
| 00:31.47 | mastergoon | there are no half pixels |
| 00:32.15 | brailsmt | you could choose a dimension so small in real life that you cannot subdivide it further, in which case this would apply to real life things too :) |
| 00:32.18 | hyriand | there's subpixels.. but those are still limited.. |
| 00:32.22 | mackstann | if you limit yourself to meter precision, then you can't splice a meter |
| 00:32.30 | mackstann | but it still behaves the same, doesn't it? |
| 00:32.58 | mackstann | other than the fact that you can't divide it into smaller pieces of course |
| 00:33.05 | hyriand | mackstann: yes.. the precision is the limiting factor.. which is exactly why there is a difference between math and computer science |
| 00:33.13 | brailsmt | what is that constant that give the smallest unit of increment possible in the physical world? |
| 00:33.46 | brailsmt | *sigh* |
| 00:33.46 | hyriand | brailsmt: real world doesn't really apply.. math does.. in which an infinite precision is possible |
| 00:34.00 | mackstann | when i think of pixels, i don't really think of the pixels themselves |
| 00:34.01 | brailsmt | hyriand: yeah, i'm just splitting hairs |
| 00:34.02 | mackstann | i think of the grid they're on |
| 00:34.11 | brailsmt | :) |
| 00:34.16 | mackstann | if you think of the grid, then what i'm saying makes sense, i think |
| 00:34.20 | hyriand | (I told you it was philosophical) |
| 00:34.25 | mackstann | if you think of the squares, then what you're saying makes sense, i think |
| 00:34.31 | brailsmt | its fundamental though... |
| 00:34.41 | brailsmt | there are lots of things that don't make sense in pixel-verse |
| 00:34.45 | brailsmt | :) |
| 00:34.54 | hyriand | yeah, like subpixels :P |
| 00:35.29 | brailsmt | for example, if you draw a line 5 pixels high, then one 5 pixel to the left, how many pixels are in the 'hypoteneuse'? |
| 00:35.46 | brailsmt | % |
| 00:35.46 | brailsmt | 5 |
| 00:35.58 | mackstann | did you guys learn this in school or something? |
| 00:35.58 | mackstann | am i missing something here? |
| 00:36.00 | mackstann | is this like, "pixel theory" or something that i just haven't learned? |
| 00:36.01 | brailsmt | pythogoras need not apply |
| 00:36.28 | brailsmt | mackstann: yes, my graphics class... though this is just conceptual |
| 00:36.29 | hyriand | mackstann: I learned it from Qt and investigated further |
| 00:36.55 | mackstann | anything i should google for? |
| 00:37.33 | brailsmt | hyriand: why do you track left and right in awidgets? |
| 00:38.41 | hyriand | brailsmt: I don't.. but ARect has a right and bottom property |

| 00:41.00 | pmazer | luckily i have locks on my doors |
| 00:41.44 | hyriand | mackstann: if an onscreen rectangle has a (1,1) geometry and a top-left coordinate-pair of (0, 0).. what would be the coordinate pair for the bottom right pixel? |
| 00:42.33 | mackstann | 1,1, if you're thinking in a grid |
| 00:42.37 | mackstann | which is how i think about it |
| 00:42.53 | hyriand | mackstann: I'm talking about the actual coordinate of the pixel |
| 00:42.57 | mackstann | but i suppose when it comes down to drawing, that's not right |
| 00:43.13 | mackstann | it would be 0,0 |
| 00:43.30 | hyriand | and there's the difference between 2d and a display |
| 00:44.10 | hyriand | a display is a collection if uni-dimensionals |

| 00:55.16 | mackstann | yeah, it makes sense now |
| 00:55.27 | mackstann | if i just think of it as blocks (pixels) instead of a grid surrounding them |
