Nolgthorn: Jan 30, 2001; The pendulum of the mind alternates between sense and nonsense

It's a bit like cheating because far less than being a really cool thing, it's more like practically a working product. Over the last year or so I've been building this Vue app that works like a poor man's single sign on. Instead of giving all of your social media data to whatever company were to implement it, it instead gives them nothing but a uuid.

Since I figured no business would ever implement such a sensible thing. I tacked on the ability to generate email addresses that you can plug into their signup form.

Then it works the same way, essentially, as long as you have a password manager because these addresses ("6f3meitj.o53u1qx5 @ getinbox.io") for example are impossible to remember. But if it were implemented as a single sign-on solution, it would just perform a redirect and authorise a session the same as all the rest of them.

https://www.getinbox.io

It's also a notification system. So if your site were to implement it, you could send email-like messages to users without having to deal with email just websockets instead.

Yeah I tested that creating 10 calendars and checking the first five with the Wikipedia results. Then again the program just bakes in the Italian festivities, and it would take a bit to stop using all those statics for a console app which just spits out a calendar in a default ditectory.

If I could fix the above problems (statics, lack of tests), how would you bundle different festivities from different countries? I was thinking about reading a json into a dictionary, excluding mobile festivities... Pro / Cons?

Doing unit testing for Gauss's Easter algorithm - which is different from the one posted - will be an interesting exercise in the limits of unit tests since Gauss's algorithm famously gives the wrong answer for some years. You'd better know to check Easter in 4200 when writing those tests!

I'm currently working on a realistic building generator. It utilises squarified treemaps and another white paper for the logical construction of it (links below). Currently randomly places doors but each RoomData construct contains a tag along with flags like NOCONNECT(<list>) that will determine what must be connected, what cannot, what needs windows, etc, etc.

In the long term I am cooking up actors for different styles of windows, doors and trim, which again will be flagged and placed appropriately. You can already specify wall and floor materials which is nice. Last bit is to have each room contain a list of appropriate items and place them around. This is done by each item actor containing info such as general placement (CENTRE, WALL, CORNER, etc), and a bit of a humanising factor with regards to both rigidity in placement (do you want everything lined up, or have a bed a bit further from the wall than the dresser?) as well as angle wiggle room (because realistically no one places everything at straight angles).

That's the long term goal anyway!

Note: Rendering done in UE4 but I intend to eventually make it platform agnostic as far as the data and manipulation structures go. Rendering is a you problem :P

That's actually addressed in the second paper! Although I am taking a cheat's method. Basically, it takes all vertexes and figure out what rooms need to be connected to the through-corridor. I then find the optimum shift (up or down) and resize the rooms intersecting the corridor.

See this:

Yes, you can absolutely create intersections such that the lost area of each room is minimised, creating non-rectangular rooms, and that is in the cards. But right now I am lazy :v:

I'm working on a toy model that simulates epidemics. I've stared way too long at graphs of cases/deaths, read too many papers about various factors that impact the spread of covid/other diseases, and seen way too many models trying to make predictions. Earlier in one of the covid threads I'd been playing around with some spreadsheet models and it was a really interesting exercise.

So I decided I'd start hammering out my own model in C#. I know it will never be all that accurate, but it's more just fun I've been working on. It models a handful of things like vaccination, travel between regions, seasonal changes. It also takes a ton of inputs for things like secondary attack rate in various settings, frequency of travel, how many locations a person can potentionally visit. It's not based on taking real world numbers and making future predictions but rather in a totally fabricated setting.

It's a console app that takes JSON files or manual input for the various parameters to build the model and outputs some console logging and dumps a lot more data to CSVs so I can make graphs in google sheets.

Compared to the other stuff here, it's not the most advanced thing by a long shot. It is however useful for embedding a cell from an informal database that is a Google Spreadsheet atop of some README, wiki, forum post, or web page.

It's a simple Go server that uses Google's API to output JSON that https://shields.io can read. Mix it in with some simple Vue generator front-end to take public spreadsheet URLS and tada.

The badge generator web UI can also make BBCode for embedding (along with modern Markdown and so on).

I've already used it for this and that. The former outputs a running bounty total and the latter is community annotation progress.

Love threads like this. Some of you have mad chops.

Here's a really early dev screenie (still prototyoping really) of me and my pals "weird west" narrative roguelike where everything is turnbased but you have a high degree of control over the combat (in this screenshot you can see I'm aiming the gun manually). This character has skills like throwing dynamite (modify the turns to burn out the fuse, blow holes in the level, shoot it if you need it to explode early!) and richoceting bullets off of scenery, enemies, yourself etc.

We think the game is mostly going to be about positioning and area control. You are very fragile and so are the baddies. Putting a bullet in your gun takes a turn, so you need to manage your spacing, stay out of enemies sight lines (the can only shoot in cardinal directions), and keep away from melee monsters.

Hey nerds. I think the last thing I posted in this thread was me working on a procedural floorplan generator. Lotta stuff has happened in my life, but guess what, work has continued.

So basically there's some whitepapers that other people here have used to generate floorplans and they work great, using squarified tree maps. I had that project pretty sorted and it was awesome. I then discovered a whitepaper that had some very nice algorithms for realistic layouts and generation of cities, from a top down generation. I was like, hell yeah gonna use that. Then I found out they had made a UE4 demo of the project, so I snagged that. In the process I noticed something.

https://github.com/magnificus/Procedural-Cities

118 forks. And if you go through them I think not one of them has had any actual work done. None. Which bodes well, because people forked it thinking "gee whiz, free procedural cities that will make an entire game for me!" like so many people do. Then they see the code and say gently caress this. I ran the demo and was pretty happy with the layout and general design of buildings, and I figured it was a good start.

My goal is not to make a game. That's boring. My goal is to first cure boredom by giving myself a project, and second is to create tools that will help actual devs prototype games quickly, giving them a base. So no running off and going "ooh cool, now to add spaceships!" Very focused on the goal.

Step one was changing a lot of code. A lot. Basically the UE4 demo provided made some assumptions:
1. It was a demo for a paper, not a product. So the code is justifiably not modular or neat. Or commented much.
2. It is designed to generate during playtime, not beforehand. I however wanted it to be a dev tool, so it needed to be modified to generate in editor so devs can see what they're working with.

Those two factors were big. So I've been tweaking and changing things. It now generates in editor, instead of during runtime. The code has been much tidied (although to my shame not really commented because my brain was on fixing) and made more modular, removing dependencies on a lot of weird things. It can now, on my baby laptop, generate cities of up to 300 roads. To give an idea of that, it generated this within a couple minutes on my laptop:

Because of the generation it means every building is able to be entered, filled out, etc. The visuals aren't amazing, obviously, but it does the trick.

Ripping out a bunch of static code has definitely helped the neatness of the whole thing, but there's a bunch to do. Right now my checklist before initial release is:
1. Material pools. Because each building is tagged as a specific type I can create a nice neat container of materials and have each assign a different one to each building. Simple build should very much help with monotony.
2. Incorporate the floorplan generator. The provided code and paper point out that interiors are not well done. They essentially consist of random lines for walls, and they make poor use of space and don't feel realistic. So the floorplan project I made is going to be put in as a way to provide proper interior designs. Other advantages will be that the floorplan treats each room as a separate but simple object, meaning I can quickly assign materials to individual rooms without worrying about the exterior building.
I will note though that the floorplan assumes a rectangular shape for the building. The current (temporary) planned workaround is to simply build based on a rectangular container of the building and trim the rooms as needed. This is a poor solution, and purely temporary.

Future things to do will be:
- Visual improvements. Adding proper surrounds, pillars if needed, etc. Little things to flesh out
- Better material designation. Having each building have a (relatively) unique texture is good, but I want to provide the ability to specify ranges for materials to be modified (HSV shifts etc). The idea is if you had several bedrooms they could all use the base painted wall texture, with a specified HSV to provide many different randomised versions on generation with low overhead. Should help with making it more interesting.
- Using the individual room objects to take the space and add pre-made actors into it using a set of rules to designate where it would be placed, with fuzziness factors such as rotation and offset to make it a little more humanised. I hate when procedural stuff is all right angles.
- Elevation consideration. This is the big one that I'm doing a lot of research into. The generator assumes a 100% flat ground. Which isn't ideal. So the idea is that once a city is generated it will take the elevation at each building and either build up on a base or level down (or both!) so buildings are still sound, but also can be built into elevated ground.

So this is what I've been working on! It's amateur and there's probably a billion similar projects that do this better, and that's okay, because this keeps me sane. Thanks for reading!

Edit: No one cares but I made updates. I added specific helper components that work as material pools. This lets you specify a material pool for each building type, but right now I'm lazy and it all works off the one. But now you can specify as many materials for each part of the building as you want which is pretty rad.

Also not related to the generation itself but I tweaked the visual settings for the project for funsies and to show that it looks far nicer than the previous pics showed haha.

I am becoming quite happy with the progress. Also to note that the old way the materials were handled basically created a new version for each material on each building, which was not great. The new version relies on instanced materials, on the basis that if anything is tweaked it's still far more efficient to use an instance than a completely new material every time.

For some reason I thought about gopher the other day. I remember getting a gopher client on one of the disks we received when we got internet access in 1995, but not spending more than a few minutes with it as the web existed. So I start googling and next thing you know I'm looking at the RFC and, gently caress it, I wrote a basic library that handles some basic stuff like directory listing and downloading text/binary files. Then tonight I threw together some quick code to traverse a server (no downloads yet) displayed using HTML with some emojis to gussy it up displayed in WebView2 (Chromium Edge) in a winform.

I doubt I'll ever finish it, but I think I spent more time goofing around with gopher in the last few days than I did way back when.

Neurion: Jun 3, 2013; The musical fruit
The more you eat
The more you hoot

Some years back I posted about a project where I made a tool for running alongside DOSBox, and when you played Star Wars: TIE Fighter it would show you a real-time combat map, mission goal readout, and other displays. One of the things that was part of the project was reverse-engineering the file format of the 3D models used in the game. At the time I got as far as the basic meshes of the models, but none of the actual surface details. Lately I've been making a similar program for Star Wars: X-Wing, and since TIE Fighter was basically built upon an expanded X-Wing engine, it was much easier to get in and reverse-engineer and disassemble X-Wing (though there were some new difficulties owing to the fact that X-Wing runs in real mode and used the older segmented memory model, while TIE runs in protected mode and uses a linear memory model, which is much more straightforward to disassemble.)

Anyways, as part of the fruits of my labors, I finally figured out how the two games store and interpret surface details on their 3D models. Here's a screenshot of a test form showing the TIE Fighter model. The green wireframe indicates the actual model mesh, while the red regions are the surface markings on the faces. The wireframe is also being rendered with very basic and primitive backface culling, to make it slightly clearer visually.

It's interesting how the game applies surface details to the meshes, as there's no actual textures used for the game's models. Models are made up of one or more parts, which split the craft up into sub-parts, such as wings, fuselage, and other details. In Star Wars: TIE Fighter these individual parts are uniquely targettable, and some can even be destroyed such as turrets and comms antennas. X-Wing has only a rudimentary version of that, in that you can't target sub-parts of a craft, but you CAN blow the shield generator domes off of the bridge of a Star Destroyer to instantly bring its shields down. Another thing I discovered during my disassembly and code tracing is another craft has destroyable hardpoints: the two turrets of the Corellian Corvette can also be blown off, which I had no idea was possible as no game documentation made mention of this and it doesn't come to play in any missions. As for turrets on all other craft, they are modeled as invisible weapons hardpoints with unrestricted targeting angles, which means it doesn't matter which angle you approach a capital ship from, as every turret can independently target you (with the laser bolts even passing through the model to accomplish this). This differs from TIE Fighter, where turrets are restricted to only being able to shoot at targets that would not result in the shot passing through the parent craft.

Getting back on track to how the games handle surface details. Faces on the model mesh can have one or more "markings", which are regions of the face that are recolored during rendering, sort of like an extremely primitive pixel shader. The model of a TIE Fighter, for example, if rendered without these markings, would have completely grey wings, without the iconic black solar panel details. The game basically stores the vertices of a marking as an index into the array of vertices that define the face the marking is on, and then a pair of ratios. The vertex of the marking is calculated by taking 3 vertices: the one indicated by the index, it's preceding vertex, and it's following vertex, and then combining them in a way defined by the ratios to basically get offsets onto the face from the vertices themselves. I haven't looked at the actual rendering code yet, as it's all complex and still going to take me time to figure out exactly how it works, but my prediction is that when a polygon for a face is being drawn, it checks if the current pixel falls within one of these marking regions and changes the color of the pixel if it does.

Hey nerds. I think the last thing I posted in this thread was me working on a procedural floorplan generator. Lotta stuff has happened in my life, but guess what, work has continued.

I've been meaning to reply to your post since I saw it show up but haven't had the time to.

What you are undertaking is exactly what I've wanted to do for some time and never find myself with any due to childcare / COVID lockdowns so I'd be very keen for you to post any updates you have as you progress through it.

I used gopher a lot back in the day, because I was accessing the net from Minix on a 286 with a modem to dial into a BBS that had a linux shell with gopher , irc, and pine and whatever it was that we read usenet from. So the web was pretty hypothetical then, I *think* it had been released (It was 1993 or 94) but I hadnt seen it yet. To be honest 90% of my net use was usenet, that bloody thing seemed immense at the time.

edit: I just dawned on me that Usenet, which was invented in 1980, can do 90% of what people use facebook for AND it was completely decentralized. No concept of anonymity or privacy though. I mean you can sort of do anonymity, but it had no concept of "private" newsgroups. Not really. I mean you could set up a local newsgroup with no distribution, but it was private only to your server.

Hollow Talk: Feb 2, 2014

For some reason, EVE Online is still strangely appealing to me on a conceptual level, even though any time I get even close to logging in, I remember how much the whole thing just feels like a job (and not necessarily a particularly fun one, at that). However, I started playing around with some bits and pieces quite a while ago, and a few months ago I felt like picking things back up, as any excuse to play around with some stuff is good, even if it's EVE-related... :sigh:

As a background, every time a player (and some NPCs) kill another player's ship, player-owned structure etc., EVE generates what is called a "killmail", essentially a permanent record of a kill. There are some third-party websites who collect these after people post them (or grant access to have them pulled directly from the API for their character), and one of them offers what is essentially a streaming API that can be continuously queried for any new killmails that arrive on the platform.

Now, naturally, there is a lot of noise in there, as I don't really care about every single dead ship. What I always enjoyed most was getting a better overview of the galaxy in its entirety, about hot spots, strategically import fights unfurling etc. For this application, I do a bit of filtering and some aggregations in the background, and I can therefore follow along passively, in my browser, in sort-of real-time (depending how quickly killmails get pushed etc.) without having to actually log in, which is the best way of playing EVE.

Since I don't really like Web Development (and because I can't design anything nice), everything looks a bit rubbish, but it does its job. :v:

(click for huge)

The application can be monitored via Grafana, and the application itself pushes new data via a (very simple) pub/sub-system (over WebSockets) to all connected browsers. There is some more stuff happening in the background, but it gives me something to fiddle around with that actually produces a visible result, so that's fun.
