SCENE STAGER

SCENE
STAGER

Cinematic camera physics married to dynamic lighting.

Seven rig profiles. Eight starter scenarios. Target-linked lights that hold exposure as the camera moves. An AI Inverse Cinematography loop that matches reference frames in 30–90 seconds. Bakes to keyframes in Blender, Maya, and Unreal — same math, same output, every host.

Inverse Cinematography as Geometric Compiler

From heuristic to theorem-grade — five substitutions, one substrate.

Scene Stager's typed compiler boundary — SceneScript → IR → MoksBakePlan → Host adapter — was designed so that anything touching the IR is pure math. The Inverse Cinematography front-end bolts an AI loop onto this boundary; the geometric tranche replaces every estimator inside the loop with a closed-form construction from discrete topology, persistent homology, and Riemannian geometry.

Each replacement preserves the dataclass schema bit-for-bit, so the heuristic baseline and geometric upgrade coexist behind a single flag. Every shipped test from the heuristic tranche still passes after the geometric tranche lands.

§ I.1

Spherical Harmonics over HDRI. Replace any external environment-map reference with an L=2 SH projection. 27 RGB floats reconstruct the ambient probe in any host via the Ramamoorthi-Hanrahan cosine-lobe convolution. Shareable presets become sub-kilobyte JSON, dependency-free.

§ I.4

Math-Over-Matter validator. Every shareable artifact passes a recursive walker that forbids file extensions (.hdr, .exr, .obj, .fbx, .blend, .png, …), absolute paths, and inline base64 payloads. The promoted preset library becomes "Cinematic Git" — diff-able, forkable, DCC-portable.

§ II.1

Fabric Transform Tree pullback. The hand-tuned 13×N JACOBIAN dissolves into the analytic pullback M_parent = Σ Jᵀ M J. Closed-form Newton step on a well-conditioned Jacobian; Levenberg-Marquardt damping handles the H_spec discontinuity. 5 iterations → 1–2 iterations.

§ II.2

Morse-Smale Lotus point. Banchoff cyclic-link classification of 8-neighbour ring sign-changes partitions the luminance manifold into Neumann domains. The Lotus point — contained extremum of the primary domain — is theorem-grade robust to window blowouts and compositional clutter.

§ II.3

Betti signature. The H_spec gate fires on persistent-homology invariants of the specular mask: β₀ for components, β₁ for enclosed loops. Machined panels (β₀ large, β₁ ≈ 0) clamp tight; organic membranes (β₀ = 1, β₁ large) relax. Topology, not brightness, drives the rule.

§ II.4

Operator commutativity for TargetLink. The seam connection on the target surface's tangent bundle replaces Euler-angle transport. The commutator ‖C_ij S_i − S_j C_ij‖_F = 0 dictates intrinsic light motion — immune to gimbal lock, well-defined at umbilics, mesh-portable across users.
