# TechIDaily Full Architecture, Resource Intelligence & Ecosystem Documentation

## 1. Overview
TechIDaily provides software tools, spatial computing research, and verified data assets for AI agents, robotics engineers, and developers.

## 2. Resource Intelligence Architecture
TechIDaily's resource system indexes over 106,000 public 3D and code assets:
- **Sandflow Sand3D (106,094 parametric objects)**:
  - CAD Dataset: 24,495 precision engineering parts (CC-BY-4.0).
  - Articraft Dataset: 9,209 articulated mechanisms with kinematic joints (CC-BY-4.0).
  - Automate Dataset: 3,169 industrial factory & conveyor systems (CC-BY-4.0).
  - SimReady Dataset: 2,334 robotics simulation objects paired with NVIDIA SimReady models.
  - Objaverse Dataset: 66,887 everyday 3D objects represented as constructive Python code.
  - Native Web Explorer: https://techidaily.com/resources/explorer (Native in-app 3D-as-Code inspection, Python 3.13 constructive code viewer, kinematic joint evaluation, and OpenUSD conversion).
- **NVIDIA SimReady Assets (2,603 models)**:
  - UsdPhysics collision meshes, physical mass/inertia, PBR materials (CC-BY-4.0).
  - 100% paired with constructive Python code from Sandflow Sand3D.
- **Scenario 3D Collection (1,342 models)**:
  - AI-generated 3D assets with verified Parquet metadata and output hashes.

## 3. Technology & Delivery Rules
- Zero local 3D binary assets: All binary payloads, USDA files, and Parquet tables resolve strictly to immutable Hugging Face mirrors under SZFSPC.
- High-Performance Edge Delivery: Cloudflare Workers edge runtime with strict bundle size constraints.
- Internationalization: Full 24-locale support including zh-Hans, en-US, de-DE, fr-FR, ja-JP, and es-ES.
- Machine-Readable API: /api/resources provides JSON search, filtering, and OpenAPI 3.1 definitions.
