Kinetiq Engine — Hybrid Generative Motion Synthesis
A technical overview of the Kinetiq architecture: solving the "Gelatin Problem" via Ecological Interaction Data and a client-side WebAssembly refinement pipeline.
Author: Isaías Reis Verdin (Thirdrez Labs) Published: December 2025 DOI: 10.5281/zenodo.17849581 Type: Technical Whitepaper
Summary
Generative motion models can produce plausible movement from text prompts, but their output rarely survives a real production pipeline. Foot sliding, joint hyperextension, mesh interpenetration, and root drift accumulate across long sequences — artifacts the paper groups under the "Gelatin Problem": motion that lacks weight and deterministic contact.
Kinetiq Engine takes a hybrid approach: a generative backbone for variation, paired with a deterministic refinement layer that runs client-side in WebAssembly. The browser becomes the cleanup studio — no installs, no uploads, no desktop GPU required. The whitepaper covers:
- A formal characterization of the Gelatin Problem and its biomechanical roots
- The Ecological Interaction Data training paradigm — how naturalistic, intent-driven motion differs from controlled lab mocap
- The four-stage Kinetiq pipeline (synthesis → physics refinement → style adaptation → export)
- Real-time, in-browser refinement at 60 FPS on consumer hardware
- A privacy-preserving architecture where user animations never leave the device during cleanup

MotionPrint Protocol — Cryptographic Provenance for 3D Motion Data
A privacy-first protocol for authenticity in generative 3D pipelines: client-side Ed25519 signatures, embedded directly in the file. Zero servers, zero uploads, mathematical trust.
Author: Isaías Reis Verdin (Thirdrez Labs) Published: December 2025 DOI: 10.5281/zenodo.17843580 Type: Protocol Specification
Summary
As generative AI accelerates 3D content production, attribution and chain-of-custody are increasingly hard to verify. Existing 3D watermarking techniques (spectral embedding, vertex displacement, texture watermarks) are destructive, format-specific, and easily stripped by routine workflow operations. Worse: most verification systems force creators to upload their work to a third-party server.
MotionPrint takes the opposite approach. It defines a non-destructive provenance schema that signs motion files using Ed25519 elliptic-curve signatures, embedded in spec-compliant metadata containers (extras for glTF/GLB, header comments for BVH). Verification runs entirely in the browser via WebAssembly — the file is never transmitted. The paper covers:
- A canonical, deterministic JSON payload schema for signed provenance
- Format-specific, non-destructive embedding strategies (glTF/GLB and BVH)
- A client-side verification pipeline using the audited
@noble/ed25519library - Sub-10 ms verification latency with under 400 bytes of overhead
- Automated PDF Certificate of Authenticity generation with verification QR
The framing matters: MotionPrint is provenance (attestation), not DRM (restriction). It tells you who signed a clip and proves the bytes are unchanged — without locking anyone out, calling home, or tracking creators.
