Build a measured exposure and grading path in Three.js. Use for a 64x36 encoded luminance meter, asynchronous readback, weighted log-average exposure, asymmetric adaptation, single tone-map ownership, and a generated 32-cube post-tone-map LUT.

基于 SOC 职业分类
Implement physically motivated sky and aerial-perspective systems in Three.js. Use for planetary atmospheres, ground-to-space transitions, Rayleigh/Mie scattering, precomputed LUTs, depth-based transmittance and inscattering, sun/moon discs, and atmosphere-aware lighting.
Implement production bloom in advanced Three.js scenes. Use for HDR signal ordering, bloom-node controls, dual selective bloom with guaranteed material restoration, scene-relative emissive hierarchy, and effect-isolation diagnostics.
Direct advanced Three.js camera systems. Use for scale-aware chase rigs, thrust lag, side/orbit cameras, body-relative up vectors, quaternion handoffs, authored cinematic framing, floating origins, pointer-look controls, camera collision constraints, projection ownership, and lifecycle restoration.
Build a deliberate final-image pipeline for advanced Three.js scenes. Use for depth, normal, albedo, and history ownership; GTAO or bent normals; bloom; eye adaptation; tone mapping; 3D LUT grading; effect-local render targets; and pass diagnostics.
Build advanced procedural animation in Three.js. Use for launch kinematics, gravity turns, staging, spin docking, target-frame decomposition, spring-follow motion, rotating-frame alignment, peeling debris, analytic transform timelines, frame-rate-independent response, and quaternion control.
Build authored procedural buildings and architectural kits in Three.js. Use for massing grammars, exposed-edge analysis, façade bays, profiles, arches, cornices, roofs, ornaments, material-slot mesh compilation, deterministic variants, and procedural city assets.

Treat exposure, tone mapping, grading, and output conversion as distinct stages. Tune them from measured HDR signal, not by stacking compensating color operations.
HDR scene
→ luminance meter
→ adapted exposure
→ tone map
→ creative grade / 3D LUT
→ final output conversion
Read references/scene-referred-color-pipeline.md for the exact 64x36 meter, encoded readback, adaptation constants, 32-cube LUT, and signal-ownership ambiguities.
Use $threejs-bloom for HDR glow contribution and
$threejs-image-pipeline when this color path must share ownership with AO,
atmosphere, or effect-local render targets.
