| 00:30 | < McMartin> | Also, this application appears to not run on my phone because my phone does not, I think, have a D-pad. |

| 15:38 | < Vornicus> | gah, brain, no, I do not have the time nor skill to pull that off, stop trying to think of modified lighting models for minecraft with randomly-scattered corners. |
| 15:39 | < Tamber> | Oh, you know you want to~ |
| 15:43 | | Alek [omegaboot@1526F6.9A8C26.9BD24E.3E88DC] has joined #code |
| 15:44 | < Vornicus> | (the difficulty: With randomly-scattered corners, the faces no longer all point the same direction -- so they should change their lighting slightly in accordance. Not much, though - my curent guess gives a 10% change, at most, in location, which gives at most about a 12 degree angle, which gives at most a 3% change in lighting. The problem is that you can't really change the face normals without |
| 15:44 | < Vornicus> | getting some effects that screw up the way light works in minecraft in general.) |

| 20:09 | < Vornucopia> | Oh oh oh I see how to do this now. |
| 20:11 | < Vornucopia> | So what I actually would do is have six lights - one from each cardinal 3d direction - and each poly only gets light from one of them. Then to change the incident light level I use a poly color other than white. (in opengl your thing gets its light level from its "color" and the local lights; then the texture gets applied, multiplied by that light level.) |
| 20:12 | < Vornucopia> | This keeps the original Minecraft lighting mechanics and still makes the lighting vary a bit with the roughness. |
| 20:14 | < celticminstrel> | Wait, what are you doing? |
| 20:14 | < Vornucopia> | (you have to make sure that each light only hits one set of sides because otherwise you get an up-to-10% increase in light from being hit side-on.) |
| 20:15 | < Vornucopia> | So I had this crazy idea. |
| 20:16 | | Kindamoody|out is now known as Kindamoody |
| 20:16 | < Vornucopia> | What if instead of always being perfect cubes, minecraft rendered the cubes slightly off kilter. |
| 20:17 | < celticminstrel> | Um, okay? |
| 20:17 | < Vornucopia> | With each corner offset a little bit (no more than 10%) from where it should be. |
| 20:19 | < Vornucopia> | The effect however isn't really visible on "flat" surfaces except through some minor distortion of the texture; thus, a small lighting change becomes useful. |
| 20:24 | < Vornucopia> | But the lighting change from being off kilter like that is a 2%-or-less drop from straight-on lights... and a 10% /gain/ from side-on lights. |
| 20:26 | < Vornucopia> | If minecraft light worked on actual occlusions this would be easier. |
| 20:29 | < Vornucopia> | (because then light could simply originate from wherever it, you know. originates from.) |
| 20:34 | < Vornucopia> | I'm actually not sure which would be better, really. |
| 20:34 | < Vornucopia> | or or or. |
| 20:35 | < Vornucopia> | what if the light comes from the direction that is toward increasing brightness. |
| 20:38 | < Vornucopia> | ...would actually make the sides of any hole really dark. |
| 20:40 | < Vornucopia> | not that the smooth lighting doesn't make small holes really dark already. |
| 20:48 | < Vornucopia> | Meh. It's all masturbation until I get around to actually rendering anything. |
| 20:50 | < Vornucopia> | (but the point is for it to look something like this: http://tech.mit.edu/V117/N53/dungeonkeeper.53.gif ) |

| 21:09 | | * Vornucopia thinks about the euclidean algorithm. |
| 21:21 | < gnolam> | I prefer the non-Euclidean algorithm. Much better at finding the Greatest Cthulhian Divisor. |
| 21:22 | < Vornucopia> | >_< |
| 21:32 | < Vornucopia> | So I was thinking about how you could actually pull out powers of 2 (and 5, if you're a human instead of a computer) relatively quickly, which allows you to possibly find the gcd faster. Take for instance 599/919; the first remainder is 320, which you can pull out 64 (or 320, if you're human) from quickly, and then you're left with 599/5 or 599/1 and you're practically done instead of fighting with it for another 5-6 divisions. |
| 21:36 | < TheWatcher> | Argh, language clash |
| 21:36 | < Vornucopia> | ??? |
| 21:37 | < TheWatcher> | Interesting fact: gcc can't compile perl code! |
| 21:37 | < Vornucopia> | ...no it can't! |
| 21:38 | < TheWatcher> | (spent all afternoon writing perl, apparently my brain hasn't caught up to the fact that I'm now writing C) |
| 21:41 | < Tamber> | -chuckles- |

| 22:48 | | * TheWatcher wonders if there's an emacs script that will convert lines containing only spaces into empty lines on saving... |
| 22:49 | < jerith> | Probably a couple of lines of elisp. |
| 22:49 | < Tamber> | Of course there is. (I don't know where, or who wrote it, and haven't even seen it; but, if experience bears out...) |
| 22:49 | < Tamber> | ;) |
| 22:49 | < jerith> | Personally, I prefer to just highlight trailing whitespace and fix it by hand. |
| 22:50 | < TheWatcher> | heh, delete-trailing-whitespace will do it, I just need to hook it into the save |

| 22:55 | < Tamber> | ...so, no change from normal, then. |
