Advanced AI Prompt for Low-Poly Abstract Noise Particles

Act as an Avant-Garde WebGL Artist. Architect a Three.js background comprised entirely of floating low-poly geometric particles (e.g., Tetrahedrons or Icosahedrons). Utilize the [GEOMETRY_DETAIL] parameter to dictate the harsh, chunky face count. Algorithmically distribute these geometries using a 3D [NOISE_TYPE] field (like Simplex or Perlin) to prevent uniform clustering. Each individual particle must be assigned a randomized, independent [ROTATION_SPEED] vector and a mathematically mapped [COLOR_VARIANCE] based strictly on its absolute position in 3D space. You must implement this utilizing `THREE.InstancedMesh` combined with a 'dummy' Object3D to calculate and update the transformation matrices, ensuring thousands of complex shapes render at a locked 60fps.
