0 A.D. Art as GLB

Units, buildings, animals, trees and rocks from the open-source real-time strategy game 0 A.D., each actor resolved into one complete model with its props, textures and animation clips (walk, run, idle, attack, death and more).

Files

Folder	Size	What	For
objects/	1.53 GB	meshopt geometry, WebP textures	three.js, Babylon.js, any glTF viewer with the meshopt decoder
objects_ktx2/	1.87 GB	meshopt, KTX2 textures (ETC1S colour, UASTC normals), mipmaps	WebGPU and WebGL games: textures stay compressed on the GPU
lods/	2.99 GB	three simplified levels: 50, 20 and 6 % of the triangles	distance LOD, crowds, far props
mobile/	1.13 GB	25 % of the triangles, textures at most 512 px in KTX2	phones and light laptops
engine/	5.28 GB	no meshopt, no quantization	Blender and desktop engines that cannot decode meshopt
collision/	4.7 MB	convex collision shapes, plain glTF	Rapier, Jolt, PhysX, Unity colliders

metadata.jsonl has one line per item: title, kind, licence, authors, triangle count and the path and size of every tier. The Dataset Viewer and load_dataset read data/*.parquet: the same rows with the mesh (Mesh, decoded by trimesh) and the thumbnail (Image) embedded. Thumbnails are in thumbs/.

For web games and WebGPU

Load the objects_ktx2/ files for games: KTX2 textures stay block-compressed on the GPU (BC7 on desktop, ASTC or ETC2 on phones), so they take a fraction of the memory of decoded WebP. Switch to lods/ by distance and to mobile/ on phones. collision/ holds convex shapes for physics.

Measured on 12 items spread over triangle count. Phone page: 390x844 at 3x, pixel ratio capped at 2, CPU throttled 4x, network at Chrome's Fast 4G (150 ms, 9 Mbit/s), so phone load includes the download. The GPU is a desktop RTX 3060 and is not throttled: frame time shows the CPU side only, a real phone GPU is slower. VRAM is geometry plus texture bytes on the GPU.

three.js WebGPU:

import * as THREE from 'three';
import { WebGPURenderer } from 'three/webgpu';
import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js';
import { KTX2Loader } from 'three/addons/loaders/KTX2Loader.js';
import { MeshoptDecoder } from 'three/addons/libs/meshopt_decoder.module.js';

const renderer = new WebGPURenderer({ antialias: true });
await renderer.init(); // KTX2Loader needs to know which compressed formats this device takes
const ktx2 = new KTX2Loader().setTranscoderPath('https://cdn.jsdelivr.net/npm/three@0.187.0/examples/jsm/libs/basis/').detectSupport(renderer);
const loader = new GLTFLoader().setKTX2Loader(ktx2).setMeshoptDecoder(MeshoptDecoder);
const gltf = await loader.loadAsync('https://huggingface.co/datasets/codepawl/0ad-art-glb/resolve/main/objects_ktx2/fauna-arctic-wolf/fauna-arctic-wolf.glb');

Use it in 67js

67js loads these files as they are:

npm install 67js@npm:@codepawlhq/67js meshoptimizer

import { Renderer67 } from '67js';
import { loadGltf } from '67js/addons/gltf';
import { MeshoptDecoder } from 'meshoptimizer';

const asset = await loadGltf('https://huggingface.co/datasets/codepawl/0ad-art-glb/resolve/main/objects/fauna-arctic-wolf/fauna-arctic-wolf.glb', { decoders: { meshopt: MeshoptDecoder } });
const renderer = new Renderer67(document.querySelector('canvas'), asset.parts, { ground: true });
renderer.render({ eye: [1.5, 1.2, 2], target: [0, 0.5, 0] });

Tested

Every file was loaded and drawn (drawn pixels counted) in each engine, three.js 0.187.0 and 67js 0.15.0, files from a local copy of this repository.

Changes made: Actor XML resolved into one model per actor: the most frequent variant of each group, props attached to their prop points, textures applied (the player colour mask baked to the default blue player, cutout alpha for foliage), animation clips imported onto each skeleton and merged by name. Scale set to 0.4 m per game unit. Converted from Collada and DDS to GLB and PNG, then meshopt-compressed, LODs, a mobile tier, an uncompressed engine tier and convex collision hulls. The pack is released under the same CC BY-SA 3.0 licence.
