Excavator

A tracked excavator whose arm solves rather than poses: name a spot and two-bone IK works out the boom, stick and both hydraulic rams.

Interactive demo, running in a sandbox. Drag inside it to look around.

What it is

A tracked digger with a boom, a stick and a bucket on rams. Point it at a spot and the arm works out how to reach, so it can dig, swing and dump. For a building site, a quarry or a yard.

It has 3,232 triangles and 12 named parts, including: trackRollers, tracks, trackFrame, house, cabGlass, boom, stick, bucket.
Named parts are separate nodes, so you can move or hide them individually.

Load it at runtime — do not rebuild the geometry on the page:
  npx modelkit vendor .        # from antics-modelkit, puts glbload.js + three next to your page
  import { loadGLB } from "./glbload.js";
  const parts = await loadGLB("./model.glb");   // [{ name, geometry, material }]
  for (const p of parts) scene.add(new THREE.Mesh(p.geometry, p.material));

To change its proportions instead of using it as-is, download the recipe, run
`npm i antics-modelkit three`, edit the arguments and `npx modelkit build`.

Published with its recipe by its author, who states it is original work. We host both files; we have not re-run the recipe ourselves.
