selwyn: throw a cardboard box in front of a moving bus, and i suspect you would see problems with single floats (aka scales actually are different enough to be a problem with single floats, if i remember correctly)
8:13:16
shinmera
It's a problem with high speeds and it's a problem if things are far away (large enough worlds)
8:14:41
|3b|
and "large enough" isn't all that big, aren't you in the cm range a few km from origin?

ACTION 's brain wasn't being particularly cooperative to start with, then there was an ice storm at the beginning of feb that dropped a few trees on my car, house etc (somehow without actually doing any visible damage to either), which was somewhat stressful and distracting
8:18:52
|3b|
lot less rough than it could have been, since the tree could have easily squashed the car :p
8:21:43
|3b|
ACTION 's brain is possibly trending back towards usability, but not wanting to do the "need to do" tasks like dealing with those branches tends to be a problem since if i think there is something else more important i should be doing i end up not doing anything :/

acquiring medication is on that list of things that causes problems (though tends to get ignored)
8:25:21
shinmera
I fortunately don't suffer from ADHD stuff like that, but I have started taking Lexapro/Cipralex/Escitalopram in December and it's helped my depression a lot.
8:26:03
shinmera
Yeah, just trying to say that it can be absolutely worth it to get that stuff done.
8:36:28
|3b|
doesn't help that i'm very bad at any sort of remembering/imagining of 'sensory' type stuff (including stuff like state of mind), so i can't even really tell if things are working or not if it isn't a huge difference
8:37:37
shinmera
Have you tried keeping a journal? Like, just jot down a sentence or two before bed?
8:38:25
shinmera
Like, as far as I understand the antidepressants aren't happy pills anyway, but if they work they prevent doomspirals and other holes. Which it definitely has for me.
8:38:59
shinmera
So it's not that it has made me happier, really, but it has prevented me from falling into endless cycles of "I fucking suck"
8:40:09
shinmera
Even just that little can make you more aware and mindful of yourself, and that can help on its own.
8:40:35
|3b|
ACTION isn't sure if i have a different sort of depression from others, or if i just happened to have different context that affects it, or if i just happened to have good enough ways of coping
8:41:57
|3b|
but i could see how if i had more external constraints, that "not doing anything" could turn into failing to meet said constraints in ways that would inspire negativity
8:44:15
shinmera
I don't know where you're located, but surely there's gotta be *some*thing in reachable distance?
8:49:16
shinmera
Anyway, I unfortunately don't know much about the system in the US, but if you ever want to chat about this sorta thing, let me know.
8:53:32
|3b|
probably only really US-specific parts are "adhd meds are scary drugs so need to be prescribed and picked up in person with written prescription" and "i need to deal with stupid insurance stuff" :/
8:59:37
|3b|
hmm, restitution slot defaults to 0.5, but constructor defaults it to 0.0, which seems slightly confusing
9:09:08
|3b|
looks like it isn't even really possibly to make a table of "real" values, depends on too many other parameters
9:23:40
shinmera
I was very surprised that I couldn't find a ready to use table in some other engine
9:43:58
|3b|
looks like people tend to just store a value per material and combine them somehow (multiply, etc)
9:45:55
|3b|
one thing i read suggested friction is complicated enough that you might want per-pair values if you want good driving
9:47:13
|3b|
(and your example list probably also shows same thing, velcro-velcro is very high, but velcro-anythingelse is probably pretty low
9:48:11
|3b|
and yeah, good driving might be different enough from the default case to be completely separate
10:04:28
|3b|
cool, it's on my list of things that would be interesting to do soon, though not sure that implies much for "likely to do soon"
10:05:12
shinmera
I need to decide what to do next because I really don't want to work on implementing GJK
10:05:13
|3b|
ACTION should really find some way to produce income at some point, and that probably doesn't really qualify :/
10:07:48
selwyn
and it writes code which is then (with the programmers approval) executed in the repl
10:09:43
shinmera
I've been thinking about refactoring the spatial query structures into their own library and at least adding a grid3 implementation.
10:10:56
|3b|
unity apparently lets you pick how to combine them per material (avg,min,multiply,max)
10:11:25
selwyn
so you can say 'computer make a chair and put it on the ground to my left' and it will write a lisp snippet to do that
10:16:45
shinmera
it just has a btMaterial with a friction and restitution value, but no library for em.
10:25:45
shinmera
Maybe I'll do a softbody thingy for cloth. That could be fun (and something I'll need).
10:30:31
shinmera
If the easiest way to get a close enough shape to describe what my model is is two partially intersecting cubes, then... well.
10:32:48
shinmera
I suppose for the intersecting case we'd need a whole computational geometry suite to compute mesh union/intersection/etc.
10:34:35
shinmera
But yeah, having the simple case covered for now at least would already be better than nothing :)
10:58:17
shinmera
There's so much stuff that can be done for 3D, I am 100% certain there's things you can offer.
12:28:58

gingerale: how do you feel about splitting off bvh2 and quadtree into a 3d-spaces library?
12:30:46
gingerale
So an octree? Sure. Not sure how bvh2 does exactly so I'll have to read on that first but it shouldn't be too tough.
12:31:10
shinmera
I mean just taking the source files and putting them into a library separate from trial
