| 00:04 | <@Alek> | well, as a moon is actually a satellite... I don't know yet if any natural satellites have their own natural satellites (the balance may be VERY finicky), but our moon at least has had artificial satellites temporarily. |

| 06:32 | <@celticminstrel> | The stencil buffer doesn't seem to make sense. |
| 06:40 | <@celticminstrel> | Okay, so if I understand this right, to draw to the stencil buffer you do something like glStencilOp(GL_REPLACE). |
| 06:49 | <@celticminstrel> | I guess I'll see if this works later. |

| 21:12 | <@celticminstrel> | Well, the intro screen drew, then I had to sort through a number of resources not getting loaded, and then it got stuck in a dialog event loop because I forgot to create the window. |
| 21:14 | <@celticminstrel> | The only problems are that the delay before the intro screen didn't happen, and the intro picture appears on the botton left instead of centred. |

| 21:41 | <@celticminstrel> | Okay... the texture seems to have been stretched to fit instead of repeating. That's definitely not what I want. |
| 21:45 | <@celticminstrel> | And now it's not stretched but still not repeated. |
| 21:47 | <@celticminstrel> | I wonder if the issue could be related to the fact that I'm only using a subrectangle of the full texture... |
| 21:49 | <@celticminstrel> | Or I'm just using the wrong destination rectangle. That'd do it. But now it's stretched again... |

| 22:40 | <@celticminstrel> | I can't figure out why the texture is scaling instead of repeating. :/ |
| 22:41 | <&McMartin> | What are the UV coordinates? |
| 22:41 | <&McMartin> | Your options should be *clamped* vs. repeating IIRC |
| 22:44 | <&McMartin> | (I've missed what it is you're actually doing here, other than something involving OpenGL) |
| 22:44 | <@celticminstrel> | I'm not sure what the UV coordinates are since the library I'm using abstracts this away, but I've set the texture rectangle to a 64x64 area, and the area being drawn to is quite a bit larger than that. |
| 22:44 | <@celticminstrel> | And it's quite clear that only that 64x64 area is being drawn. |
| 22:44 | <~Vornicus> | (there's also, uh, what's it called -- where you fall to a solid color or transparent, though I don't know how often that shows up) |
| 22:45 | <~Vornicus> | celticminstrel: The library is Wrong. |
| 22:45 | <@celticminstrel> | Could be. |
| 22:45 | <@celticminstrel> | I think it's supposed to be normalizing the texture coordinates internally. |
| 22:47 | <&McMartin> | I'm not sure it's wrong; if you tell me "I have a 64x64 pixel texture and I want you to put it on this giant polygon" that says "stretch" to me unless something special is happening |
| 22:47 | <@celticminstrel> | Hm. |
| 22:48 | <&McMartin> | If it's "I have this 512x512 texture and I want you to put this 64x64 subset on this polygon" that's the only thing I know how to do without writing a custom shader |
| 22:48 | <&McMartin> | Because yeah, a cornerstone of OpenGL spritework is "I don't have to worry about rotozoom; I just put the vertices in different places and that entirely solves my problem" |
| 22:50 | <~Vornicus> | hooray for no futzing with rotozoom |
| 22:51 | <@celticminstrel> | It's also possible I'm using the library wrong. |
