I'll adjust the ReferenceArcs component to create slightly less pronounced parabolas for a more subtle visualization.

Let's update the ReferenceArcs component:

Here are the key changes made to tone down the parabolas:

1. In the createArc function:

   • Reduced the base height multiplier from 1.5 to 1
   • Decreased the distance scaling factor from 0.2 to 0.1

2. Adjusted individual arc heights for each reference type:

   • Principal references: 0.6 (from Interest) and 0.7 (from Total)
   • Rate references: 0.4
   • Time references: 0.2
   • Interest references: 0.2
   • Previous Total references: 0.5
3. Slightly reduced the curve tension from 0.8 to 0.7 for smoother, less pronounced arcs

These changes result in more subtle parabolic arcs that still clearly show the relationships between cells while being less dramatic in their curvature. The arcs will now have a gentler, more understated appearance that maintains the visual representation of cell references without dominating the scene.

The color scheme and overall structure remain the same, ensuring consistency with the previous versions. You should now see:

• Visible arcs that rise above the spreadsheet plane, but with a more subtle curve
• Varying heights for different types of references, still making them distinguishable
• Smooth, less pronounced parabolic curves that clearly show cell relationships

This adjusted visualization provides a balanced view of the spreadsheet structure and cell references, allowing for a clear understanding of the data relationships without overpowering the overall scene.

I'll modify the ReferenceArcs component to display the arcs only on the bottom side of the spreadsheet plane.

Let's update the ReferenceArcs component:

Here's a summary of the changes:

1. ReferenceArcs component:

   • Modified the createArc function to create arcs below the plane by inverting the Y direction.
   • Adjusted the Y position of all start and end points to be slightly below the plane (-0.01 instead of 0.01).

2. Main scene (app/page.tsx):

   • Changed the initial camera position to view the spreadsheet from below (y: -10 instead of 10).
   • Adjusted the pointLight positions to better illuminate the bottom side of the spreadsheet.

These changes result in a visualization where:

1. The spreadsheet plane remains visible from both sides (thanks to the existing THREE.DoubleSide material).
2. The reference arcs now appear only on the bottom side of the plane.
3. The initial view and lighting are optimized to see the arcs from below.

The color scheme, arc heights, and overall structure remain the same as in the previous version. Users can still use the OrbitControls to view the spreadsheet from any angle, but the default view will now show the arcs on the bottom side.

This new setup maintains the clear visualization of cell references while presenting them from a different perspective. It offers an interesting and unique view of the spreadsheet structure, highlighting the relationships between cells from below.
