| 04:35 | | * Vornicus tries to figure out how to create a random spherical starfield. |
| 04:40 | < Stalker> | Generate two sets of degrees and a length, the first set of degrees determines how the second set intersect the a plane. |
| 04:40 | < Stalker> | You could also just generate a random cubical starfield and prune everything outside your circle. |
| 04:42 | | kwsn [kwsn@Nightstar-ca9721ae.dyn.centurytel.net] has joined #code |
| 04:42 | <@Vornicus> | "two sets of degrees"? |
| 04:42 | < Stalker> | Circular degrees? |
| 04:42 | < Stalker> | 0 to 360? |
| 04:42 | <@Vornicus> | Right, but, how do you mean by that. |
| 04:42 | <@Vornicus> | Or rather ,why two sets of them, and how do you get them together so you don't have a strong pole bias. |
| 04:42 | < celticminstrel> | Solid angle. |
| 04:43 | < celticminstrel> | For spherical coordinates; r, ?, ?. |
| 04:43 | < Stalker> | First you generate a horizontal angle, then you generate a vertical angle.. |
| 04:43 | <@Vornicus> | And get around the pole bias... how? |
| 04:43 | < Stalker> | Pole bias? |
| 04:44 | < celticminstrel> | Hm. |
| 04:44 | < Stalker> | Why would there be pole bias? |
| 04:44 | <@Vornicus> | Pole bias. by choosing latitude randomly, stars are twice as dense at 60degrees north than at the equator. |
| 04:45 | < celticminstrel> | ...wait, what? How? |
| 04:45 | <@Vornicus> | There's only half as much room. |
| 04:45 | | EvilDarkLord [jjlehto3@Nightstar-f1ccbb45.hut.fi] has joined #code |
| 04:45 | < Stalker> | I don't get it. |
| 04:46 | <@Vornicus> | If you walk around the equator, it takes you 24,000-ish miles. If you walk around the world along the 60th parallel, you walk 12,000-ish miles. |
| 04:46 | < Stalker> | Yeah, how is that pertinent? |

| 04:47 | < Stalker> | Two numbers between 0 and 360 and one between 0 and 100 shouldn't be too hard. |
| 04:47 | < Stalker> | I don't see why it would bias any pole in particular, mostly because it's two circles. |
| 04:48 | <@Vornicus> | Because the second circle always goes through the poles. |
| 04:48 | <@Vornicus> | It would bias both poles. |
| 04:48 | < Stalker> | Ah. |
| 04:48 | <@Vornicus> | toward both poles, that is, and away from teh equator. |

| 04:49 | < celticminstrel> | Are spherical coordinates precisely the same as altitude/latitude/longitude? |
| 04:49 | < Stalker> | I suppose you could generate a third number and yaw the second axis that much. |
| 04:49 | <@Vornicus> | celticminstrel: usually that's what you use, yes, but the problem with doing it that way is that as latitude increases, longitude does less work. |
| 04:49 | <@Vornicus> | ...hm... |
| 04:50 | <@Vornicus> | ...the sand reckoner. |
| 04:50 | < celticminstrel> | You could just generate cubical coordinates and discard those that don't fit in the sphere... |
| 04:50 | < celticminstrel> | Or cylindrical. |
| 04:51 | < Stalker> | I suggested that too. |
| 04:51 | < celticminstrel> | I know. |
| 04:51 | <@Vornicus> | Actually I don't care about distance, is the thing. |
| 04:51 | <@Vornicus> | Which means... oh, this is cool. |
| 04:52 | < Stalker> | Ignoring the gyro in the middle, this is what I'm trying to explain: http://ismashphone.typepad.com/.a/6a00e55225079e8834013486224972970c-500wi |
| 04:52 | <@Vornicus> | Two variables: 0..2pi, -1..1. Draw the point on a cylinder, then project it straight toward the axis. |
| 04:53 | <@Vornicus> | Onto the surface of the sphere. |
| 04:54 | < Stalker> | What do you need a spherical starfield for? |
| 04:54 | <@Vornicus> | Curiosity, mostly. |

| 18:21 | < celticminstrel> | Okay, so I'd like to have a generator that basically does the same thing as calling set(...) - that is, it iterates through an iterable, and filters out duplicates. |
| 18:21 | < celticminstrel> | (Python) |
| 18:21 | | Tarinaky is now known as Caeldir |
| 18:22 | < celticminstrel> | Am I correct in supposing that there's no way to do this with itertools and generator syntax? |
| 18:22 | < celticminstrel> | The only way I can think of is writing a generator function that keeps a list of objects already returned. |
| 18:22 | < celticminstrel> | Which sounds horribly inefficient. |
| 18:26 | <@jerith> | Keep a set of objects? |
| 18:27 | < celticminstrel> | Hm? |
| 18:27 | <@jerith> | Sets have O(1) lookup. |
| 18:27 | < celticminstrel> | ...well, that's somewhat better than O(n) for lists, true. |
| 18:29 | < celticminstrel> | I suppose that requires the elements to be hashable. |
| 18:29 | <@jerith> | It does. |
| 18:29 | < celticminstrel> | Which shouldn't be a problem; just make sure they're tuples, not lists. |
