| Anteru | I don't get it | 10:37 |
| Anteru | my first line in aqsis.cpp is #define _SECURE_SCL 0 | 10:38 |
| Anteru | the STL has: #if !defined (_SECURE_SCL) | 10:38 |
| Anteru | #define _SECURE_SCL 1 | 10:38 |
| Anteru | #endif | 10:38 |
| Anteru | I can click on "ignore" but it stops in that assertion anyway | 10:41 |
| Anteru | and the docs here http://msdn2.microsoft.com/en-us/library/aa985896(VS.80).aspx cleary state that I should have them disabled | 10:42 |
| Anteru | Ah | 10:45 |
| Anteru | I've built boost with _SECURE_STL on :/ | 10:46 |
| Anteru | Which is the default | 10:46 |
| Anteru | So the workaround is to rebuild boost with _SECURE_STL off | 10:46 |

| pgregory | various interesting things. | 13:47 |
| pgregory | I'm working on a new FB | 13:47 |
| pgregory | A new developer has stepped up to implement point cloud/brickmap support. | 13:47 |

| c42f | Hi Paul | 15:28 |
| pgregory | hi Chris | 15:28 |
| c42f | pgregory: do we do any kind of anisotropic filtering ATM? As far as I can tell the SampleMap() function(s) don't really do it. | 15:29 |
| pgregory | no | 15:29 |
| c42f | Ok, that's what I gathered. Do you think it's worth investigating? | 15:31 |
| pgregory | sure | 15:31 |
| pgregory | if you can identify a valid case where it would provide a significant advantage, then it's bound to be worth it. | 15:32 |
| c42f | Cool. I'll have to understand it a bit better first... | 15:32 |
| c42f | Also, what do you think about the bilinear vs trilinear defaults? I'm quite strongly in favour of making trilinear the default. Bilinear filtering often seems to cause some nasty artefacts. | 15:33 |
| pgregory | gets my vote, as long as it's not an order of magnitude slower, quality is always primary. | 15:35 |
| pgregory | of course speed is a very close second ;-) | 15:35 |
| pgregory | gotta go, maybe back later, cya | 15:38 |
| *** pgregory has left #aqsis | 15:38 | |
| c42f | Ah damn, hope to see you later Paul ;-) | 15:38 |
| c42f | (damn that Paul went before I could distract him with further questions that is) | 15:49 |
| mafm | :D | 15:56 |
| *** AlexK has quit IRC | 16:19 | |
| c42f | Hmm, with a simple scene containing only a textured linear patch (ie, should be heavily texture-limited if anything is), bilinear filtering took 2m26s, while trilinear took 3m8s. That's only a ~30% speed increase, for double the number of texture accesses. | 16:24 |
| c42f | s/double/half/ | 16:25 |
| * c42f certinally doesn't consider this an "order of magnitude" ... | 16:25 | |
| mafm | an order of magnitude would be like 20min | 16:28 |
| c42f | Exactly. | 16:29 |
| c42f | Better that we get something correct here I feel, rather than a bodgy job at only 30% speed increase... | 16:30 |
| *** Anteru has joined #aqsis | 16:34 | |
| mafm | I think that too | 16:35 |
| renderguy | c42f: Hi Chris... next step would be (on-going) optimisation anyway. ;-) | 16:38 |
| renderguy | c42f: Weren't you thinking of changing the default texture filter to 'sinc' rather than 'box' too? | 16:42 |
| c42f | Yes, I was thinking of doing that for mipmap generation. | 16:43 |
| renderguy | c42f: I'm assuming there's little/no penalty in doing that either? | 16:44 |
| c42f | The new mipmap generation is _at least_ an order of magnitude faster than the old (really), so speed shouldn't be an issue. | 16:44 |
| renderguy | c42f: 8-) | 16:44 |
| c42f | I can run an 8x8 sinc filter over an 800x800 image in ~1sec. | 16:44 |
| c42f | Not blindingly fast, but certinally usable. | 16:44 |
| c42f | The old code took ages to do that - at least a minute, say. | 16:45 |
| renderguy | c42f: Seems you've really been getting into the texturing stuff, with good results, congrats. | 16:45 |
| c42f | Well, thanks :-) You should see some nicer results soon, when I've finally fixed the trilinear filtering properly. (I have a solution ATM, but it's a nasty hack ;-) | 16:46 |
| renderguy | c42f: Still being influenced by 'The Dark Side' (Pixie)? ;-) | 16:48 |
| c42f | I'd *really* like to know how 3delight does it's gaussing filtering without stochastic sampling... | 16:48 |
| c42f | renderguy: The pixie codebase will be a useful source of ideas at times I think. | 16:49 |
| renderguy | c42f: I think we'd like to know how 3Delight does a lot of things. :-D | 16:49 |
| c42f | I'd like to think that | 16:49 |
| c42f | oops | 16:49 |
| c42f | I'd like to think that the open source world represents a whole pool of solutions, and people can mix and match from here and there to get inspiration. | 16:50 |
| c42f | It's hard not to think of Pixie as "the competition" sometimes though ;-) | 16:50 |
| c42f | Hopefully they can get inspiration from parts of our codebase at times. | 16:51 |
| renderguy | c42f: I'm sure they have, as have others. | 16:51 |
| c42f | and regarding 3delight, yep it'd be very nice to peek at thier code twice in a while :-) | 16:52 |
| renderguy | c42f: Perhaps we need to get a sleeper in there. | 16:53 |
| * renderguy goes covert. | 16:53 | |
| c42f | hehe | 16:53 |
| renderguy | I've been getting into Paul's eqshibit (new FB) work, it's already my prefered FB! | 16:55 |
| renderguy | ... it's seqsy. :-) | 16:56 |
| c42f | :-) | 16:56 |
| * renderguy makes note of that name for potential use in future. | 16:57 | |
| c42f | All these words with q's in them are so darn slow to type :-( | 16:59 |
| *** Anteru has quit IRC | 16:59 | |
| c42f | aqsl aqsis eqshibit teqser... Argh! | 16:59 |
| c42f | ;-) | 16:59 |
| renderguy | c42f: I still trip-up on eqshibit occasionally, but getting use to it. | 16:59 |
| c42f | When I first saw that I couldn't help reading it as eqsh*t all the time :-/ I think I've got used to it now though. | 17:01 |
| renderguy | c42f: Maybe we'll drop the 'h', so it scans better. | 17:01 |
| c42f | yeah, actually eqsibit seems much nicer to me | 17:02 |
| c42f | much more obvious what it's meant to represent phonetically. | 17:02 |
| renderguy | c42f: That said, if it changes I'll spend a while getting used to typing the *right* (new) name. ;-) | 17:06 |
| renderguy | c42f: BTW... would you be interested in (simple) documenting your texture/filter work on our blog? | 17:09 |
| renderguy | c42f: http://aqsis.blogspot.com | 17:09 |
| c42f | Seems like for bilinear interpolation, the artefacts can be made much less objectionable if the mipmap level is chosen more appropriately... | 17:09 |
| * c42f has just been playing. | 17:10 | |
| c42f | Oh, I didn't know we had a blog. | 17:10 |
| * c42f goes to look | 17:10 | |
| renderguy | c42f: Not many do, as it's still a WIP. | 17:10 |
| renderguy | c42f: I need to update my posts, but other such contributions by the team *are* welcome... to show what goes-on behind the scenes. | 17:11 |
| * renderguy next update will regard eqshibit. | 17:12 | |
| c42f | Sounds cool. I'd have to find time to write it though. | 17:14 |
| c42f | I guess the tone is light. I wrote rather extensively on my earlier tests with mipmapping on the wiki. That was rather detailed though. | 17:14 |
| c42f | s/tone is light/tone should be light/ | 17:15 |
| c42f | Anyway, I'd better go. | 17:15 |
