Things are looking good pairing the terrain-diffusion model output with hello-terrain!

Refactoring #HelloTerrain (hello-terrain.kenny.wtf) so you can create arbitrary topologies. Here's a torus-world example. I can't wait to try out a planet-scale example of this with atmospheric scattering! #theejs #r3f

I made an interactive "poster" for next week's creative coding meetup! ccnyc.space inspired by doom metal album covers~

Currently trying to figure out how to do some medieval land use simulation, but I'm having trouble thinking about the "substrate" or like basic node primitives are. Perhaps subdividing voronoi?

I've uploaded a small example of a world you can walk around in, using the raycast and terrain query API of the terrain library to power a simple character controller. Go have a stroll! #threejs #r3f #HelloTerrain hello-terrain.kenny.wtf/examples/ray...

Raycasting character controller + terrain heightmap stamps (from github.com/Roland09/Ter... ) #threejs #r3f #helloterrain

Kenny.wtf @kenny.wtf · 19/03/2026

Terrain raycasting API is working so well~ First time I've ever been able to embody a character and walk around one of my terrain scenes! #threejs #r3f #helloterrain

Kenny.wtf @kenny.wtf · 11/03/2026

My hello-terrain library is finally getting picked up by game devs :) hello-terrain.kenny.wtf #threejs #webgpu #r3f

per-tile bounding boxes~

Kenny.wtf @kenny.wtf · 27/02/2026

The terrain query API is coming along well, and it's fast! ⚡ Game dev stuff like placing objects, snapping characters to the ground and responding to mouse clicks is going to be mega easy~ #threejs #tsl #webgpu

Kenny.wtf @kenny.wtf · 19/02/2026

I changed the backend of #HelloTerrain to use a texture atlas instead of a flat buffer, hopefully that will make it easier to interpolate between values, because I want to start putting trees and stuff on these terrains! #threejs #r3f #webgpu hello-terrain.kenny.wtf/docs/core/el...

011

Kenny.wtf @kenny.wtf · 17/02/2026

Updated the hello-terrain library to alpha.5. Now you can provide an elevation function using #threejs's #TSL to create procedural terrains or consume heightmaps (or both). ⛰️ hello-terrain.kenny.wtf/blog/posts/e...

Some more dessert :)

Kenny.wtf @kenny.wtf · 09/02/2026

Alright, I think I might be getting someplace with this terrain library. Amazing what an environment map, a normal map, and some voronoi can do. Infinite Starlit Dessert #threejs #webgpu

Kenny.wtf @kenny.wtf · 08/02/2026

I've got the heightmaps + normalmaps generating smoothly now, both implemented as extensible little worklets. I love it when a plan comes together~ It's cool to see that uniforms and parameters update and see the effects in real time #threejs #webgpu

Introducing hello-terrain/work! A small reactive work-graph library for typescript! Organize compute with automatic dependency detection and aggressive memoization. Especially made for hot loops like your renderer update cycle~ hello-terrain.kenny.wtf/work

032

Kenny.wtf @kenny.wtf · 31/01/2026

I'm excited about terrain generation mainly because there's not nearly enough fantastic world types out there! Here's an early experiment with a hollow-earth topology. I'm looking forward to fill this with fantastical atmospherics to see how it would look. #threejs #procgen

Kenny.wtf @kenny.wtf · 28/01/2026

Snowed-in this weekend learning to channel-pack PBR materials and then compress them with BCn. I've been avoiding learning texturing for a long time, but I've had so much fun, and learned so many techniques. Can't wait to apply them to terrain! #threejs

030

Kenny.wtf @kenny.wtf · 23/01/2026

Enjoyed creating some new docs for my WIP terrain-rendering library for #webgpu and #threejs. I'm having a hard time architecting things, I want it to be easy to use and super-performant for large open worlds. Learning a ton in the process~ hello-terrain.kenny.wtf/docs/advance...

020

Kenny.wtf @kenny.wtf · 02/11/2025

Frustum-culling now comes standard in the #HelloTerrain system~ I always enjoyed the debug demonstrations like these, now I get to make my own! #threejs #webgpu #tsl #procgen

Kenny.wtf @kenny.wtf · 01/11/2025

Normal map compute stage - fixed ✅ You can't tell where the seams are anymore, how about that! #procgen #terrain #threejs #webgpu

020

Kenny.wtf @kenny.wtf · 31/10/2025

Heightmap compute stage: done ✅ Normal map compute stage: some flashing, overwriting index issues? 💥 Texture splatting stage: todo already feels very fast compared to previous implementation, huge terrains running at 60-120fps #procgen #threejs #webgpu #terraingen

i hope i can live in a world where i never have to look upon highways again

Kenny.wtf @kenny.wtf · 24/09/2025

wheeee, it mostly works in react-three/fiber, with updating the params in real time

050

Kenny.wtf @kenny.wtf · 24/09/2025

My #webgpu compute shader terrain engine now can make LODs from a quadtree, at about 0.2ms (only when the quadtree needs to resolve, not each frame!). Next step is to use that data to generate normals and texture splats. Users can simply pass in an elevation function! #threejs #tsl #procgen

030

Kenny.wtf @kenny.wtf · 08/09/2025

Hello Terrain library progress, now using the improved terrain geometry, and a bunch of new convenient #tsl nodes~ This shows a new TerrainMesh which handles the instancing, compute shader stuff coming next. #threejs #webgpu #procgen

140

Kenny.wtf @kenny.wtf · 05/09/2025

Oh yeah this is feeling nice and slick. Going to make it easy to read from all those compute shader buffers

010

Kenny.wtf @kenny.wtf · 05/09/2025

The default planeGeometry from #threejs has this quirk in the vertices where if you pull down the outer ring to make a skirt (a way to hide terrain seams), you would get this little alcove from a crossing edge Made a new geo has four-way symmetry to fix it, it's pretty~

000

Kenny.wtf @kenny.wtf · 01/09/2025

Some bad math happening at the edges and skirts, but that's heightmap data being streamed from the compute pass only when the cpu quadtree updates. Next is to mop it up and implement the normal compute stage. #threejs #tsl #webgpu

051

Kenny.wtf @kenny.wtf · 31/08/2025

Was able to get a compute stage set up. Now I'll write all the data to a heightmap, normals, and texture splat buffer for each node only when the quadtree resolves differently, instead of doing it for each vertex each frame. #threejs #tsl #webgpu #procgen

010

Kenny.wtf @kenny.wtf · 14/08/2025

This looks and feels amazing. How far a little bit of quadtrees and textures will get you. Zooming off a drop from a 100km tall "mountain" #threejs #tsl #webgpu

1131

Kenny.wtf @kenny.wtf · 12/08/2025

I think this is textures working, weighted by slope and texture heightmaps. The textures are pretty detailed which creates a lot of noise when far away, I wonder how to fix that #threejs #webgpu #tsl

240

Kenny.wtf @kenny.wtf · 03/08/2025

Normals are now blended properly according to this wonderful article, so they're reoriented to the underlying surface: blog.selfshadow.com/publications... I've made a gist of the #TSL: gist.github.com/kenjinp/5900... #threejs

I have achieved perhaps playstation-era graphics (but big scale) #threejs #procgen

everything looks better with some cheap fog

Kenny.wtf @kenny.wtf · 25/07/2025

FBM noise looks pretty good, still trying to figure out how to get the normals to be calculated on the frag shader with TSL. At least I think that's the problem, the shading is flat on the polygons. #threejs #procgen

010

Kenny.wtf @kenny.wtf · 22/07/2025

hop in nerds, we're doing huge webgpu worlds~ #threejs

060

Kenny.wtf @kenny.wtf · 20/07/2025

Hey TSL isn't so bad, just need to figure out how to get the worldUV in all my nodes... Very fun to play with. I wanted to light all the rivers into a rainbow, but best I got was sea level. #threejs

020

Kenny.wtf @kenny.wtf · 19/07/2025

Okay, I managed to get terrain skirts looking okay and math'd a bit better, even though my plane tiles have two more triangles than they should ¯\_(ツ)_/¯
