As a long time engine programmer, it makes me sad how baroque the leading engines of the day are.
It doesn't have to be this way.

imagine if you could program a computer without needing a doctorate

@efi show me a PhD that can program a computer! :P

There is a serious rabbit hole - er - black hole relating to generalizations of Latin squares that would take multiple lifetimes to explore. Ain't nobody got time for that!

That includes interleaved gradient noise, for example :)

Friday me: I bet orthogonal (taguchi) arrays could be used for sampling!
Sunday me: oh. I've seen this paper before derp! https://cs.dartmouth.edu/~wjarosz/publications/jarosz19orthogonal.html

the problem with telling people to "just read the docs" is that sometimes the docs are just this:

like, what the fuck does that even mean

@demofox@mastodon.gamedev.place avatar

@eniko so true. If it was hard (significantly harder than it needed to be) it's a failure on the part of the hw/sw designers :P
A computer is a whole lot of really simple components. The rest is abstraction.
Agree 💯 😂

@demofox Another place for blue noise, I think? https://www.youtube.com/watch?v=yQqpe2jFMd4

You want each "tooth" in a rasp to cover the part of the cut that the other teeth didn't go through. And you can't get the teeth too close to each other :)

@jon_valdes that's neat! Probably low discrepancy sequences too

We've had a preprint on hold for over a month on arxiv, and have since seen papers related to our work announced at conferences. It's starting to defeat the point of arxiv at this point.
We emailed but didn't get a useful response (just keep waiting pls).
What's the hold up? Ai gend papers clogging the works?

If I was more of a bad ass, I would have like 10 remote data entry jobs, but automated, and use that to fund my independent game dev and research projects.
Hell, why aren't more of us using our powers to take advantage of the system? :)

On a tangent, learning about the "taguchi loss function" (not a loss function in the ML sense), it's nice, but I feel the modern world has a "one sided taguchi loss function" where corps only care about their loss.

@glassbottommeg I have a knack for leaving just before layoffs and shutdowns. Kinda wishing i stuck around for severance some of those times past and tried that too 🙃

I've been using a landscape for my ground just because it was easy to fill with temp data, and it's already set up for virtual texturing and sampling the ground colour.

Problem is, landscapes are not designed to be edited at runtime. Like, at all. Looks like a huge ballache. Which for a game with procedural levels is not ideal. So, that's out then, building my own ground patches it is https://forums.unrealengine.com/t/runtime-landscape-editing/631305

Ugh, 10pm is too late for me to start a blog post on how orgs constantly set designers and design teams up for failure then wonder why the competition outdoes them.

demofox,
@demofox@mastodon.gamedev.place avatar

@hbuchel sounds like lots of companies I know of that have more money than sense... buying up semi successful studios, having them make derivative games, then layoffs and shutdowns when it doesn't work out.

Can anyone explain what the global and local dictionaries are for in functions like pyrun_string?
Not groking it from the sparse info in the docs, and examples with either make a new dictionary and send it as both, or will get some module directory as global and make a new dictionary as local.
What's the behavior here?

demofox,
@demofox@mastodon.gamedev.place avatar

@pervognsen I have a bunch of scripts to run in a "game world" and am thinking they each get the same global dict, and their own individual local dict. As a way to make global, and per script variables, using globals()[key] and locals()[key] respectively.
Does that fit with the functionality as you remember it?

demofox,
@demofox@mastodon.gamedev.place avatar

@pervognsen thanks for the info! I was planning on compiling each individually, but combining them is an interesting idea.
