Assembly · Construction plant and machinery
Tracked excavator
A tracked excavator built from just four placed parts, each a unique component model: a base, a boom, a stick and a bucket. The split follows the way the machine is described, so the arm is three separate pieces that meet at the base.
Since the parts are separate models, a developer can read the assembly to see how they are positioned relative to one another, then place the same four models in a different arrangement if the scene needs a different pose or a bucket at another angle.
It is one of eight machines in the Construction plant and machinery pack. The others are the mini excavator, piling rig, site dumper, skid-steer loader, tandem roller, telehandler and wheel loader, all built the same way from separate parts.
An assembly from the Construction plant and machinery pack: 4 placed parts positioned by an assembly file, using 4 unique component models. Load the whole thing with the pack's three.js loader, or read the file to build your own variations.
The picture is a studio render. View in 3D loads the GLB files themselves in three.js; switch between high, medium and low to compare.
This scene on its own: the assembly file and the 4 models it places, each in high, medium and low detail, plus the three.js loader and a working example (2.2 MB zip).
