@alightinastorm :D

@sweriko another sudden erik banger

~2ms volumetric clouds in threejs/webgpu, we even got some shooting stars :)

@Toyota414 wgsl

@sweriko hlsl????

@sweriko How does this look from space?

@renderfiction its gonna be something fun for sure :D

@sweriko I'm excited to see where this is headed

early prototype of a procedural active ragdoll in javascript

@SwarnimaPrasad ty! yep that was my initial experiement behind this

@sweriko This lookss so Cool! Is this the implementation of non euclidean space

a Threejs portal to Narnia? The experience includes getting yeeted off the skilift and run over by other players and uh, thats it. snow.sweriko.com

@DennisSmolek haha thanks :) they are called octahedral impostors, indeed just a billboard that samples from an atlas containing bunch of possible view angles, usually only used for distant tree lod, you can read more about here shaderbits.com/blog/octahedra…

@sweriko Very sad.. Jumping in the volcano has me in a cave... The fact sounds work here are wild. Fun little project! How are you doing the trees? its some kind of billboard but seems to rotate?

@thaonlyjonathan and all the assets are just placed using noise

@sweriko This is great lol. Can I ask how you made the terrain? Did you make a level editor for this or import one from a 3d modeling program? I'm currently trying to make a threejs level editor.. Trying..

@thaonlyjonathan its actually real elevation data from earth ^^

games in javascript could close this gap

@Colonthreee I kinda plan to do the same xd

@sweriko I would rather use your system as the next-step LOD for this, as when there are more vertices than pixels it's overkill. TwT)

I'm sorry @sweriko but I am gaining on you now. Here are 512000 entities just to test the extents of the GAT. I know I need to improve the CPU->GPU communication but at least it didn't kill my machine, yet. TwT)/

@RobertBeckebans damn

@sweriko It runs with default settings on my Ryzen 9 16 Cores and Geforce 2070 Super with 7 fps

simulating half a million people in javascript. no 3D models, bones, LOD or VATs

bunch of thoughts -current demo has around 180 total unique frames across 5 base character variants, with the current approach I dont think you should go beyond 200 unique frames total, the texture array just gets too big -the walking animations are quite smooth with around 30 frames each, so this would be a first point to optimize, maybe one can reduce each animation to 5-10 frames and do some interpolation or maybe it even fits the intended art style of the game -subvariants are almost free though (small palette changes), but you cant really change the silhouette of the character, just its clothes/gear/colors to some degree. The second most obvious optimization is the texture atlas itself -In most games that dont actually want a pixel art style, you would only use them for LOD and swap for mesh at closeup, in that case you: -dont need such big texture atlases (the demo has 12x12/144 view angles of the 3d model baked at 2k resolution, you only need 4x4 or 8x8 at 1k at distance) -could probably get away with a walk cycle or whatever animation just beeing a few frames I am not sure yet how applicable this approach is for games in general, but can imagine it to work for a handful of games that are specifically built around this.

@sweriko this is pretty cool. have you evaluated constraints on animation count + skin permutations? any kind of clear and obvious memory bounds that would prevent this from scaling into more real usecases with a game?

@SeanEllul right now they are just walking around all day

@sweriko Super cool! Are there any specific behaviors for them? Really cool use of 3js

@splizard basically like this

@sweriko What do they look like close up?

@benrayfield jup, but in this case I also have it all baked offline, would take a minute to do it live, at least for animated ones ^^

@sweriko Are u saying ur using sprites generated from a 3d model? Thats how Donkey Kong on SNES got its sprites but they precomputed not live.

@sweriko Total war in JavaScript now….what a time to be alive 😂
