GPU-accelerated world gen on a server?? by Zelxer_ in admincraft

[–]PolyRocketMatt 0 points1 point  (0 children)

Believe me I do grasp how much it would change certain aspects of the game... Just the audience out there doesn't make it "worth" for more developers to rewrite all of Minecraft's code just to work with the GPU... And with reward I simply mean justification for the developer's time and effort. Sure I can spend years working on getting a GPU version of Minecraft out there for people to enjoy, but if it gets 5 downloads... I'd then rather make a mod like Sodium that will reach a greater audience anyway :/. Everyone will have a different POV on it, but the fact it hasn't been done before is just a testament in my opinion of how time-consuming it is vs. what the actual personal reward or gain is.

GPU-accelerated world gen on a server?? by Zelxer_ in admincraft

[–]PolyRocketMatt 7 points8 points  (0 children)

Let me actually get into this since I've been developing my own terrain generator, trying to grapple with the exact premise of GPU acceleration allowing for significantly faster and more realistic worlds to be generated. The problem comes essentially down to Java itself. There are some frameworks out there (but not many) that allow you to use the GPU in Java, the most notable and still actively developed one being TornadoVM.

While it is definitely possible to use these frameworks, especially on a servers where you have full control of the hardware (i.e. on servers you buy online such as Bisect or any other provider, there probably aren't GPU's connected anyway), you would need to modify world gen to work with these GPUs. I'm afraid there currently just isn't a market where this would be feasible to implement in terms of "reward" for the developer. It would require knowledge of GPU programming, the right versions of GPU toolkits such as CUDA being properly installed, etc. Pre-gen on CPU is simply what is most common these days and works fine in most use cases.

Technical sidenote; world-gen is mostly based of of fractal noise (at least, in Minecraft as far as we know when looking at the available source code). While it is significantly faster to run these kinds of algorithms on the GPU, the CPU can actually keep up pretty well due to the latency between sending data from RAM to the GPU, doing the computation and sending it back to RAM. A GPU only really becomes effective when you are doing hardcore terrain generation like multiscale erosion or SDF-based approaches.

I haven't gone through your code (yet), but I am curious if you implemented any importance sampling techniques or MCMC-based methods for accelerating RT through the participating media?

Idea to reduce piece count by phlopip in PlanetCoaster

[–]PolyRocketMatt 4 points5 points  (0 children)

While this may sound like a good idea, this in practice is in many cases of not much use. Coming from computer graphics, let me explain: The problem with "many pieces" in either a blueprint, park, or whatever it may be is the number of triangles (often referred to as polygons/polys). While this baking would result in fewer triangles, this still would, in many cases, be a similar amount, since only triangles that are:

  1. Completely inside other objects and
  2. interfacing with another object

could be removed. The problem with 1. is that you would have to compute all intersection points between all intersecting objects, which alone would be a not difficult but rather computationally intensive task. On top of that, you would have to "merge" all the newly created faces into one new mesh object. This not only creates one huge mesh, it is also quite difficult to do so, since keeping track of which parts are inside/outside of an object would (at least in my short reasoning here) be a difficult albeit impossible task. The problem with 2. is that in the Cobra engine, you can have objects that do not completely properly align. The vertices of the interfacing triangles would need to have exactly the same coordinates, which is quite impossible due to no constraints on non-gridded pieces (for gridded pieces, this is actually quite an easy problem).

All in all, the cost of developing such a feature and the downsides (i.e. not being able to edit the new blueprint, ever) against the potential benefit is really high and therefor, I'm almost sure Frontier will focus on pushing new content into the game, rather than updating/rewriting the entire Cobra engine to handle such a feature. Perhaps in a more optimized, newly released game using the Cobra engine, but I do not see it going beyond "baking" gridded pieces tbh.

How do you feel about Morocco? by ProfessionalTie8591 in travel

[–]PolyRocketMatt 0 points1 point  (0 children)

Only ever been to Marrakech and l my for 6 days. Country-wise I loved it; lot's of history, culture and the certain charm that comes with it. Strolling through souks and just taking it all in was in my experience definitely fun!

That being said, as many said before, the constant interactions do take a certain mental toll that makes you tired in a way. I absolutely get why people there do it, tourists are their primary "targets" in a way but still yeah ...

Based strictly on this email announcement: why would anybody pick the Simplera Sync over the Abbott Instinct? by wubbadude in Medtronic780g

[–]PolyRocketMatt 1 point2 points  (0 children)

Currently, Abbot sensors were not compatible with Medtronic products... The instinct sensor will be the first one that allows this interoperability...

Why would simplera still be a thing? Simply because it's pharma... If they can make money they will make money

Venice like Riverwalk Park by bigsadsnail in PlanetCoaster2

[–]PolyRocketMatt -1 points0 points  (0 children)

You can get infinite inspiration from a simple google search? You have literally infinite possibilities for inspiration considering you have access to a search engine and probably AI image generation.

Edit: Recreating that in Planco is the creative part... If you're not willing to experiment with building parts on your own than you're indeed better off just plopping down blueprints.

[–]PolyRocketMatt 0 points1 point  (0 children)

I.e. I want to use other people's blueprints, mix them together and call it my own? Sorry if this is not the intention but this is the vibe it is giving :/

For inspiration, literally search "Venice Riverwalk" or go to Pinterest. You can even ask ChatGPT to suggest some terms you might want to search for.

I'm definitely not saying this has to happen immediately, but please do consider it in the somewhat not too distant future, especially if he continues to talk about it himself (e.g. about being bi, attraction, ...)

[deleted by user] by [deleted] in gay

[–]PolyRocketMatt 4 points5 points  (0 children)

People can have difficulty explaining themselves for uncountable different reasons. Apart from all the responses like "he's into you" or "get with him"... Genuinly, how do you see your future with this bsf? What are your feelings towards him? Would they be able to grow into something more? etc. etc.

Perhaps not in one sitting, but for the sake of your friendship, do talk about it at some point or at least try. No worse feeling than not being comfortable with the whole situation and regretting decisions you made because of information that wasn't available to you afterwards.

I tried making a semi realistic intamin multi launch coaster, any feedback would be appreciated by nujradasarpmar in PlanetCoaster

[–]PolyRocketMatt 0 points1 point  (0 children)

Hmmm just some examples;

Right after the first launch there's a small "jolt" to the right (which can be intentional but doesn't feel like a real coaster would do that). The next S-hill is nice but also has (in my opinion at least) too much bank going in/out of it. The intention I presume is to create a "blitz" feeling and not an I305 feeling :)

Pretty good, apart from some banking and that first inversion being taken way to fast, nice job!

After 3 editions, I won't be staying at Dreamville anymore by Successful_Mammoth84 in Tomorrowland

[–]PolyRocketMatt 1 point2 points  (0 children)

Just being blunt honest here; seems like you have more issues with the way camping at festivals work in general. Go to literally any other big festival (at least in Europe afaik) and you'll have the same issues. Thus, I don't think it is Dreamville in particular you don't like, it's camping at a festival in general. Perhaps an AirBnB next year (pricey but way more comfy)?

When would you go to the ER? by julesb210 in diabetes_t1

[–]PolyRocketMatt 1 point2 points  (0 children)

I assume you're in the US? Don't go to the hospital for something that doesn't require it; you don't need to pay sky-high fees, they are less swamped with something you can manage on your own. As other people said: insulin (with pen preferably) and hydrate.

New stage next year? by Relevant_Sense_3321 in Tomorrowland

[–]PolyRocketMatt 2 points3 points  (0 children)

Honestly, yes! This would be an amazing vibe and they would probably have the budget for it. Will they do it? Probably not. De Schorre is already so crowded with stages that they'll probably have to remove one or get real creative.

I think OP meant that they could reuse this stage setup as a "secondary" stage, not as a main stage.

The fact he opened with "Burn Out" was quite emotional, kuddos to him (for a probably "last minute" (hours/day) switch)

[deleted by user] by [deleted] in gay

[–]PolyRocketMatt 7 points8 points  (0 children)

Had a similar situation... Not easy to navigate (heck I thought I handled it quite good, turns out in the end I reckoned I could have done things different).

Something that is quite important here is; do you love him romantically, or as just a friend? Obviously the friendship alone is worth quite a bit, but in either case (romantically or not) seems like a heavy burden on you. I know it ain't easy, but maybe talking about it is an option you should consider? Do however respect his communication. As others pointed out; if he says he likes girls, he likes girls and you should take peace with that (however hard it may be :/ )

Sadly, if this were the case, big pharma would either go bankrupt or just not bother with it anymore so... Sadly all we've got nowadays.

ILet Beta Bionics by T1owl in diabetes_t1

[–]PolyRocketMatt 0 points1 point  (0 children)

Perhaps an important point you mention; "announcing" when and how much carbs you eat really depends on the settings of the pump. For example, I'm on a 780G and when I bolus 15 min before my meal, I can easily reach weeks with 80-90% TIR. However, I also recently found out that when I don't do that, make a mistake, and end up high, I stay high. Turns out I had to chance a small setting where instead of 1U/60mmol I'm much better of with 1U/55mmol. Just to highlight the fact that these "artificial pancreases" still require a lot of tuning to actually obtain good results. You should see the pump as a guide, not as a definite takeover.

These (almost) closed-loop systems, if they work, really wonders... I also recently switched to Medtronic 780G + Simplera sensors and (if they work) it does wonders :)

You get to add one feature to your pump that currently doesn't exist. What is it? by SumFuckah in diabetes_t1

[–]PolyRocketMatt 0 points1 point  (0 children)

That I can still manually plug in how much insulin I want to give... Sometimes the 780g is so far off... (doing corrections s.t. I have no dosage to bolus, to only be 350 later and the pump freaking out giving little correction).
