Mark a wheel's world position
A frame stands at x = 2 and is turned 90° around y. A wheel is its child, at local (1, 0, 0).
Add a small ball named marker to the scene (not to the frame) at the wheel's world position. Ask three.js for that position; do not work it out yourself.
What Check tests
- A mesh named marker exists
- The marker is a direct child of the scene
- The marker is at the wheel's world position (2, 0, -1)
- The wheel itself has not moved (local x = 1)
