SemaFrame Demo Gallery — English

Three silent-first English SemaFrame demonstrations: parametric pump placement, collision-aware living-room editing, and an editable miniature-city emergency route. These films use deterministic captured evidence and synthetic scenes; they are not field scans, live infrastructure feeds, continuous-path simulation, or engineering certification.

SemaFrame v0.3.0 — Spatial Modeling & Reality

SemaFrame v0.3.0 — Spatial Modeling & Reality

SemaFrame v0.3.0 turns the semantic spatial workspace into an editable modeling and reality environment. An approved Agent can now build exact parametric assemblies, inspect collision and bounded physics evidence, publish reusable models, import a user-supplied Gaussian capture, connect it to semantic engineering proxies, preserve the result through undo/save/reopen, and export standard modeling formats while a person remains able to inspect and edit the same authoritative Workspace.

Highlights

• Parametric modeling: exact SI primitives, editable assemblies, reusable digest-pinned models, numeric transforms, and collision-aware placement.
• Interchange: OpenUSD USDA, Manifold STL/OBJ, and an OpenCascade AP242 STEP subset from bounded lazy Workers.
• Reality Layer: PLY, SPZ v4, and SOG v2 Gaussian splats with explicit calibration, local content-addressed storage, digest relinking, semantic proxies, LOD, and context recovery.
• Agent-native workflow: 18 approval-gated MCP tools, descriptor-only Reality inspection, one-use streaming uploads, SSG 3.1 spatial understanding, and atomic revision-bound mutations.
• One human/Agent authority: UI edits, Agent transactions, rendering, history, persistence, data bindings, collision, and physics continue to share the same WorkspaceStore.

Public contract changes

• Workspace Protocol / project schema: 1.3
• SemaFrame Spatial Graph: 3.1
• Agent Guide: 2.6
• MCP server: 1.7.0
• Public MCP tools: 18
• Built-in components: 19, including spatial-primitive, model-assembly, and gaussian-splat

Workspace 1.0 through 1.2 project files migrate through the validated serializer. Projects from the removed pre-Workspace Scene/Compose runtime remain intentionally unsupported.

Upgrade

git pull
npm ci
npm run dev

Node.js 22.12 or newer is required. This repository remains a source-distributed browser application and is not published as an npm CLI package in v0.3.0.

The v0.3.0 GitHub Release should use GitHub's generated source archives only. Do not attach the current dist/ directory as a binary distribution: the optional OpenCascade WebAssembly path requires a dedicated redistribution package with complete third-party license texts and corresponding-source/relinking information.

Validation evidence

• TypeScript project references and demo source type-check successfully.
• Production Vite build succeeds with fingerprinted Manifold and OpenCascade WASM assets and a lazy Spark Reality chunk.
• Full Vitest suite: 103 files / 773 tests.
• CAD, CSG, and Reality runtime bundle verifiers pass.
• Real browser Agent smoke and Workspace smoke pass, including approval, 18-tool discovery, SSG 3.1, persistence, responsive layout, and the exclusive pre-handshake connection gate.
• npm audit --omit=dev: 0 known vulnerabilities.
• Independent Reality security/lifecycle audit: no remaining P0/P1 findings in the reviewed scope.

Important boundaries

Gaussian splats remain visual-only. Collision, mass, support, structural feasibility, CAD export, and engineering claims must come from explicit parametric, asset, or assembly proxies. Current physics is bounded feasibility preflight rather than FEA or certification. Reality binaries stay in the importing browser's private asset vault and are not embedded in project JSON.

Third-party runtime obligations are documented in THIRD_PARTY_NOTICES.md, including the LGPL-2.1-only OpenCascade WebAssembly dependency used by the optional STEP path.

SemaFrame v0.2.0 — Launch Demo

The first public product demo for SemaFrame, a semantic spatial workspace for AI agents.

Demo assets

• semaframe-demo.mp4 — 78-second 1920×1080 product tour
• semaframe-demo-short.mp4 — 18-second 1080×1920 vertical cut
• English and Simplified Chinese subtitle files

The demo covers Agent connection and approval, live Workspace construction, Universal Space Data, collision and bounded physics, live-data panels, 2D/3D interaction, and deterministic history.

The reproducible Remotion source and sanitized capture evidence are included in the repository under video/.
