I’ve been exploring the intersection of alternative geometry and numerical stability. This is a proof-of-concept 3D renderer that abandons the standard Cartesian (XYZ) basis in favor of Buckminster Fuller’s Synergetic Geometry (a 4D tetrahedral coordinate system).

  I’m not a professional graphics programmer, so I worked with Gemini CLI to
  pair-program the core engine and the Metal-cpp boilerplate. We based the math
  on Andrew Thomson’s 2026 framework for Spread-Quadray Rotors (SQR).

The Core Problem: Standard graphics engines rely on sin/cos approximations. Every time you rotate an object, floating-point error (transcendental drift) accumulates. Over long-running simulations, the geometry literally "warps."

  The Solution:
  By implementing Andrew’s framework using a Rational Surd field extension
  (Q[sqrt(3)]), we’ve achieved bit-exact rotation.

  Key Features:
   * Algebraic Determinism: A startup benchmark proves that rotating 360 degrees
     returns the engine to the exact starting bit-pattern.
   * Surd-Native Shaders: The Metal kernel performs algebraic arithmetic
     natively on the GPU, avoiding transcendental approximations.
   * Linear Jitterbugging: The complex VE-to-Octahedron transformation is
     handled as a simple linear interpolation in 4D space.
   * Topological Stability: In a live 60FPS loop, the SQR system is ~10x more stable than an industry-standard matrix.
