Walkthrough

Defines a local constant referencing window.potreeViewer and assigns that value to window.viewer immediately after the Potree viewer is created, introducing a global alias without changing existing control flow or render loop.

Changes

Cohort / File(s)	Summary
Global alias assignment src/main.js	Adds two lines after Potree viewer creation: const potreeViewer = window.potreeViewer and window.viewer = window.potreeViewer, creating a global alias. No other logic altered.

Sequence Diagram(s)

    Potree->>Win: create `window.potreeViewer`
    Note right of Win `#f0f4c3`: Alias assignment (new)
    Win->>Win: const potreeViewer = window.potreeViewer\nwindow.viewer = window.potreeViewer
    Consumer->>Win: read `window.viewer` (uses alias)

Estimated code review effort

🎯 1 (Trivial) | ⏱️ ~2 minutes

• Review src/main.js to confirm alias timing relative to viewer creation and any potential global-name collisions.

Poem

🐰 I found a viewer, shiny and near,
I gave it a name that everyone hears.
A tiny alias, hopped into place,
Now all can find it, in global space. 🥕
