February 23, 2018 [00:00:00] <DarkUranium> chrisf, but it's been on a hiatus due to something else taking priority.[00:00:14] <DarkUranium> it technically still is, but I'm semi-actively looking for a solution that will allow me *NOT* to write a custom SL[00:01:42] <DarkUranium> not that it's a huge task for what I need (which is very specific, so I can avoid implementing most shader features)[00:03:21] <DarkUranium> I need, lemme think. Apart from the basics that any language needs (y'know, arithmetic, variables, that sort of stuff), I basically need uniforms and that's about it.[00:04:13] <DarkUranium> And faked, global-scope callbacks (I've done it in GLSL before, a preprocessor that added glue code to connect the callbacks to wherever they should connect)[00:04:31] <DarkUranium> basically #define FAKE_CALLBACK(x,y,z) real_function(x,y,z)[00:04:48] <DarkUranium> (so not technically a callback as far as the GPU is concerned --- obviously)[00:05:17] <DarkUranium> Oh yeah!

I am *NOT* talking about real-time algorithms; rather, something for creating/baking AO maps for models.[00:06:49] <DarkUranium> err, not implementation, algorithm[00:06:59] <DarkUranium> I dunno what the "best" one would be for this[00:07:22] <chrisf> there's not a lot of rocket science there[00:08:24] <chrisf> sample the front hemisphere[00:08:31] <DarkUranium> I know there's a ton of algorithms, so I'm not sure what's what here.[00:08:48] <DarkUranium> (I don't even know which ones are offline and which are online)[00:09:01] <DarkUranium> by "online", I mean real-time[00:09:04] <DarkUranium> (with some exceptions, e.g. I know screen-space techniques are real-time)[00:13:19] *** Sindriava <Sindriava!~textual@94.230.153.70> has quit IRC (Quit: Textual IRC Client: www.textualapp.com)[00:13:28] <DarkUranium> chrisf, but sample until what range? How many sampling points? What distribution?[00:13:42] <DarkUranium> well, since it's a single model, I guess range can be infinite ..?[00:20:46] <chrisf> if you're not thinking too hard about it, uniform distribution, the number of rays you want to wait for, and far enough that it looks good[00:20:52] *** Tobbi <Tobbi!~Tobbi@supertux/tobbi> has quit IRC (Read error: Connection reset by peer)[00:21:44] <DarkUranium> chrisf, figured as much.

Nothing more, nothing less.[16:39:04] <chrisf> https://www.amazon.com/Mathematics-Programming-Computer-Graphics-Third/dp/1435458869 isnt a bad introduction[16:39:19] <Dariusz> already have it :- )[16:40:37] <Dariusz> I suppose I'm at a stage where I watched master painter paint a picture, and now I try to take brush in my hand and figure out what each pot of paint does/water and how to paint... only so far reading/watching master takes me, now I gotta start paiting @_@[16:41:04] <Dariusz> and imediately I dont know which pot is water which is paint which is brush.[16:41:29] <hampusw> Dariusz, DarkUranium: exactly, you get quite far by just realizing that matrices can be used to represent any linear function between vectors[16:41:42] <DarkUranium> Dariusz, https://i.imgur.com/RadSf.jpg[16:41:55] <Dariusz> I love that pic.[16:42:06] <hampusw> start by making sure you understand that kind of matrices (normal linear algebra) and then read up on homogeneous coordinates to understand how 4x4 matrices can represent a perspective projection in 3D[16:42:13] <DarkUranium> Dariusz, what I'd do is ... yeah, what he said.[16:42:21] <DarkUranium> hampusw, what I'd do is, start with linear maps. Forget computer graphics.[16:42:37] <Dariusz> https://en.wikipedia.org/wiki/Linear_map this?[16:42:49] <hampusw> DarkUranium: exactly. agree. also, without homogeneous coordinates at first, because that's confusing enough on it's own really.[16:42:49] <DarkUranium> yes[16:43:01] <hampusw> its*[16:43:44] <DarkUranium> You have one vector space, say base vectors $\vec i=(1,0,0), \vec j=(0,1,0), \vec k=(0,0,1)$, and you're trying to map it into (say) $\vec i=(0.5,0.5,0), \vec j=(0,0.0,1.0), \vec k=(0.0,2.0,0.0)$[16:43:48] <DarkUranium> write the matrix that maps them.[16:44:03] <DarkUranium> that's a good excercise, Dariusz, and once you learn to do that ^ you'll understand a lot more about what's going on.[16:44:17] <DarkUranium> hampusw, and yeah, that last ping was meant for Dariusz :P[16:44:21] <DarkUranium> err, s/ping/highlight/[16:44:29] <DarkUranium> and yes, without homogeneous[16:44:56] <hampusw> Dariusz: yeah, start with linear transformations, then read up on https://en.wikipedia.org/wiki/Affine_transformation after that and finally https://en.wikipedia.org/wiki/Homogeneous_coordinates[16:45:06] <hampusw> but give each of those quite a bit of time on their own[16:46:24] <hampusw> there's a lot of other interesting linear algebra theory to know too, but it's not really essential to understand what's going on in this context[16:47:30] <DarkUranium> ^[16:47:41] <DarkUranium> and a lot of other interesting matrix things to know, but again, not really essential[16:48:13] <DarkUranium> (e.g. I'm a fan of relation matrices, despite [for sparse relations] using up a lot of storage)[16:48:23] <Dariusz> hmmmmmmmmmmmm[16:48:33] <hampusw> DarkUranium: maths is a ton of fun :D[16:48:46] <DarkUranium> hampusw, my favorite topic were linear proofs. I was faster than the professor in those :D[16:48:57] <DarkUranium> (had the proof done the moment they finished writing the problem on the blackboard)[16:49:03] <DarkUranium> grammars were quite fun, too, though[16:49:16] <DarkUranium> for some reason, we called those "theories" (I'm sure there's a mathematical reason for that name)[16:50:16] <hampusw> DarkUranium: I loved proofs in general too. Studied pure mathematics. Reading up on graphics again now after doing unrelated software dev for some years. It's just awesome. Maths is useful for once![16:51:28] <DarkUranium> hampusw, haha[16:51:46] <DarkUranium> hampusw, well, it was useful for me in parsing, too. The way I did LL(1) verification was via relation matrices.[16:51:54] <DarkUranium> I studied comp sci, but always liked mathematics.[16:52:21] <Dariusz> o.o[16:52:41] <DarkUranium> hampusw, here's how to do it (this is a part of my thesis, translated to English; see the very last page for the "meat"): http://stdrand.com/data/verifying-ll-1.pdf[16:52:43] <hampusw> DarkUranium: Nice. Whenever you can use some mathematics, it's always really good to know it! It's like magic sometimes.[16:52:58] <hampusw> DarkUranium: awesome. I'll check later.[16:53:01] <DarkUranium> hampusw, basically, you compute 3 matrices, then do a bunch of closures & multiplications.[16:53:11] <DarkUranium> (again, last page)[16:53:12] <DarkUranium> sure[16:53:22] <hampusw> cool. it never ceases to amaze me how much can be done with linear algebra and matrices.[16:54:53] <chrisf> homogeneous coordinates arent all that crazy once you understand what's going on, too -- we use them because they make things /easier/ :)[16:56:47] <Dariusz> black magic.[16:56:48] <DarkUranium> chrisf/hampusw, I think the most insane thing in mathematics is how one goes ... "Okay, I have a hard problem here, and I'm not sure how to solve it. I know! I'll add another dimension to the problem!"[16:56:49] <Dariusz> :- )[16:57:06] <DarkUranium> example: doing (2D) delaunay triangulation by extending the points into 3D space and computing the convex hull[16:57:07] <chrisf> DarkUranium: solves plenty.[16:57:40] <hampusw> yeah, exactly. homogeneous coords is one of those really nice extensions that makes all the existing techniques useful for even more.[16:58:00] *** _gr3g_2 <_gr3g_2!~greg@pool-72-80-159-17.nycmny.fios.verizon.net> has quit IRC (Remote host closed the connection)[16:58:15] *** acksys_ <acksys_!~fritz@mail12.shutterfly.com> has quit IRC (Ping timeout: 256 seconds)[16:58:31] <DarkUranium> chrisf, another case is navigating hex grids. https://www.redblobgames.com/grids/hexagons/#coordinates-cube[16:58:33] <hampusw> I also like it how mathematicians always try to transform hard problems back to easier problems they already know how to solve. works.[16:58:53] <DarkUranium> hampusw, that's true of programmers too, though.
