Frustum-culling now comes standard in the #HelloTerrain system~

I always enjoyed the debug demonstrations like these, now I get to make my own!

Normal map compute stage - fixed ✅

You can't tell where the seams are anymore, how about that!

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

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

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!

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.

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

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~

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.

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.

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"

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

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:

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

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.

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)_/¯
