Finance Architecture True 3D

A business-grade individual tax parametric model: income as foundation, deductions as negative space, taxable income as load-bearing core, brackets as heat-stress slabs, credits as shields, and payments as satellites. Drag the geometry or use slicers.

Implementation Notes what changed

This version replaces the pseudo-3D canvas with a real Three.js scene, uses volume-based scaling instead of radius inflation, attaches HTML info cards to geometry, implements direct drag-to-adjust for selected objects, and stores/restores scenarios locally and through URL encoding. Source constants are embedded as 2026 planning assumptions with comments in the code.
