three.js scene
A convincing 3D page is mostly light and proportion, not polygon count. The White House reads as the White House because its storeys, column spacing and cornice depth are right, and because a low sun throws long shadows across it, not because every window has a frame. This skill builds scenes the way an architect's model is made: from real dimensions, in code, with lighting done properly.
Start from the starter
assets/starter/ is a complete, working scene (a round pavilion on a lawn) with everything below already wired. Copy it, keep env.js, kit.js and main.js, and replace scene.js with your subject.
cp -r assets/starter my-scene && cd my-scene
python3 -m http.server 8000 # any static server; ES modules need http://, not file://
