How to Use This Demo

1. Navigate the Scene:
   • Left-click + drag to rotate your view.
   • Right-click + drag to pan.
   • Scroll the mouse wheel to zoom in and out.
2. Inspect a Point's Frequency Response:
   • Click any red sphere on the room surface.
   • The two plots on the right show amplitude vs. frequency for that point:
   • Blue curve = Ours model.
   • Red curve = Ours model without vision input.
3. Visualize the Whole-Room Frequency Response:

   Use the buttons below the scene:

   Button	Description
   Texture	Show the room texture.
   RR: Ours	Show the reflection response map predicted by our full model.
   RR: w/o Vision	Same reflection response map but without using vision input (set vision feature to zero).

Tip: The RGB color encodes frequency-dependent reflection response, with red indicating high-frequency and blue indicating low-frequency. Hard, smooth materials tend to reflect high frequencies (red); soft, rough materials reflect low frequencies (blue).
