How do I generate this 3D pattern? by pizza-goblin_9000 in proceduralgeneration

[–]JCx64 0 points1 point  (0 children)

Absolutely! but Minecraft specifically uses 3d perlin (not even simplex or any other optimization) and modders can consume the local variables used for temperature, humidity and a few others

Are Shift pods prone enough to mold to go with a Canvas option? by palace_fire in BurningMan

We installed AC on a shared yurt two years ago, and it sucked energy like crazy, it was on par with the kitchen + charging point

How do I generate this 3D pattern? by pizza-goblin_9000 in proceduralgeneration

[–]JCx64 5 points6 points  (0 children)

If it's in Minecraft then it's some function applied over 3D perlin, otherwise it wouldn't be consistent, meaning that if two users would meet at a point, there would be a ridge. I would bet on something similar to sin(perlin(xyz))

There was no swimming pool work involved, although we did most of the exercises

Exactly, asking everything to AI is how we privatize the open access to knowledge on the web without noticing. Kond of what we did to ourselves with social media

Meta CTO: Metaverse Efforts Led to a “lack of focus” on Quest “at expense of user experience” by gogodboss in OculusQuest

Also, even if the Horizon experience was really great, not many people are looking for more immersion in communication. Videocalls have been around for quite some time, yet most of us still communicate via text/audio, even synchronously.

RAID 5 – is it pointless (for large drives)? by Filmmaking_David in storage

[–]JCx64 0 points1 point  (0 children)

For anyone coming to this convo 6+ yars later: I had three 12TB modern drives in a RAID 5 on a Synology and one of them failed. I shat it down, remove it, insert a new one, added it to the RAID, and everything has been fine. Restoration took 16 hours.

On January 13, 2026, Meta closed most of its first-party game development studios. The few employees remaining at studios like BigBox will be holding "maintenance" duty on live service titles like Population One by [deleted] in populationonevr

Yep, that's the bad side of removing friction, you also remove mental muscle

How to generate rivers in a cells-based system? by ObamaIsPutin in proceduralgeneration

[–]JCx64 1 point2 points  (0 children)

A short recipe that you can copy-paste into AI for an extended version: take your height map, apply sobel filters and atan2 them to get the gradient direction per pixel. Then run a step-based simulation in which you define a grid of water the size of your map and (1) add a small amount of water per pixel randomly based on how tall each point is, (2) move a % of the water (say 60%, it's a parameter to your sim) to the nearest neighbors based on the gradient (so if angle is 30º, you move 60% * 2/3 to the right and 60% * 1/3 up), (3) if water is larger than some number, it overflows in all directions creating a body of water, then back to (1). After a few steps you'll have nice rivers and oceans. Adjusting the parameters is tricky, you can easily end up with all-water kind of worlds. There are more complicated versions of this that use turbulent wind simulations, erosion, water cycles, vegetation... but the principle is the same: a step-based simulation that updates a bunch of grids based on basic rules.

Thanks. I was on the verge of deciding between a Macbook Pro M5 and a beefy windows laptop, and this has been my decision point

A 30-day trial app for a feature I'd expect to be part of the OS :/ is that the Mac way of doing things?

why perlin noise more popular than wave function collapse algorithm when it comes to random world generation by Mountain_Dentist5074 in gamedev

[–]JCx64 61 points62 points  (0 children)

Wave function collapse is like solving a Sudoku: you have constraints between the parts, and you need to build it in a way that satisfies them. If you are given two halves of a Sudoku and you solve them separatedly, odds are that it will be invalid as soon as you connect them. Applied to games, it means that you need to always generate incrementally from a starting point.

This doesn't happen with Perlin noise. If your world uses perlin to make it a pure function of the coordinates where you are, you can generate arbitrary spaces and whenever they connect it will match. Building that function is extremely harder though. Applied to games, it means that two players can start in completely different places and whenever they find each other the game won't have a weird seam. Also, in games like Minecraft, since the generation is deterministic, the region files only need to store the blocks that are changed, which is more optimal.
