# OpenUSD **Aliases:** OpenUSD Core Specification 1.0 **Entity class:** World substrate **Integration priority:** P1 **Collections:** [[collections/Consciousness Continuity|Consciousness Continuity]] · [[collections/Neurotech|Neurotech]] · [[collections/Machine Succession|Machine Succession]] **Canonical source article:** [[articles/Mind Uploading and AI — The Host is Reusable and the Person is the Delta|Mind Uploading and AI — The Host is Reusable and the Person is the Delta]] ## Definition **OpenUSD** — Pixar-originated interoperable scene framework now used for digital twins/robotics. ## Relationships  This entry is routed through [[collections/Consciousness Continuity|Consciousness Continuity]], [[collections/Neurotech|Neurotech]], and [[collections/Machine Succession|Machine Succession]]. Its source context is developed in [[articles/Mind Uploading and AI — The Host is Reusable and the Person is the Delta|Mind Uploading and AI — The Host is Reusable and the Person is the Delta]] and [[articles/Technologies for Consciousness Mapping and Transfer|Technologies for Consciousness Mapping and Transfer]]. Status-qualified source edges are preserved in the terminal Research Edges section. ### Key Relationships - [[wiki/Universal Scene Description|Universal Scene Description]] is associated with **OpenUSD**. Open-source scene description lineage. - **OpenUSD** is used by NVIDIA Omniverse. Shared scene representation. - [[wiki/Newton Physics Engine|Newton Physics Engine]] is associated with **OpenUSD**. Official. ### Technology and research relationships - The technical comparison identifies a convergence: **OpenUSD** converges technically with [[wiki/Digital Twin Interoperability|Digital Twin Interoperability]]. Shared scene ontology/reference semantics enable exchange across tools. ### Connections in this corpus - **OpenUSD** is connected in the corpus with [[wiki/reference-plus-delta architecture|Reference-Plus-Delta Architecture]]. Instancing stores one canonical scene asset plus per-instance transforms/overrides. - **OpenUSD** is connected in the corpus with [[wiki/World Modeling|World Modeling]]. Scene graphs provide persistent addressable world structure beneath generative elaboration. - The technical comparison identifies a convergence: **OpenUSD** is connected in the corpus with [[wiki/Standards as Governance|Standards as Governance]]. Shared world representation becomes governed interoperability substrate. ### Standards and interoperability - [[wiki/Alliance for OpenUSD|Alliance for OpenUSD]] standardizes **OpenUSD**. Normative interoperability.  ## Related Work in the Corpus  - In [[articles/Mind Uploading and AI — The Host is Reusable and the Person is the Delta|Mind Uploading and AI — The Host is Reusable and the Person is the Delta]], **Host-infrastructure crosswalk** provides the narrative context for **OpenUSD**: A durable habitat would likewise be hybrid.  ## Research Edges  #### Host–residual infrastructure patch — 2026-09-10 **Resolved aliases:** `OpenUSD Core Specification 1.0` **Collections:** [[collections/Consciousness Continuity|Consciousness Continuity]] · [[collections/Neurotech|Neurotech]] · [[collections/Machine Succession|Machine Succession]] **Canonical source article:** [[articles/Mind Uploading and AI — The Host is Reusable and the Person is the Delta|Mind Uploading and AI — The Host is Reusable and the Person is the Delta]] **Related acquisition source:** [[articles/Technologies for Consciousness Mapping and Transfer|Technologies for Consciousness Mapping and Transfer]] **Relationship source:** [[research/Mind Uploading and AI Host-Residual Ecosystem Relationship Graph - 2026-09-10|Mind Uploading and AI Host-Residual Ecosystem Relationship Graph — 2026-09-10]] #### Host-infrastructure integration Pixar-originated interoperable scene framework now used for digital twins/robotics. #### Outgoing typed edges - **HR-0253 — `used_by` → `NVIDIA Omniverse`** — **VERIFIED EXTERNAL**; evidence `ARTICLE`, `WEB_NEWTON`.
