3D Generation API Integration & Evaluation

Generate, evaluate, host, deliver — the full 3D generation engineering pipeline.

Real-world application: 3D API integration and evaluation (Chamfer distance, geometric accuracy) demonstrates you can build production 3D generation systems, not just call APIs.

What you will learn

Integrate Tripo API and Rodin API for programmatic 3D generation
Deploy Hunyuan3D for self-hosted 3D generation
Evaluate 3D model quality: mesh quality, texture fidelity, geometric accuracy (Chamfer distance)
Implement 3D model hosting and delivery: CDN, format conversion, thumbnail generation

Objective

Inspect generated assets as usable geometry, materials, and motion—not merely attractive previews. In the paired studio lab, build an evaluation pipeline that takes generated 3D models and scores them on: mesh quality (polygon count, topology), texture fidelity (resolution, PBR completeness), geometric accuracy (if reference available, compute Chamfer distance), and printability (watertight, manifold). Output a quality report with pass/fail gates.

The Problem

A team integrates the Tripo API for 3D generation. They can generate models, but:

They don't know how to evaluate quality — is the generated model accurate?
They don't know how to host models — where do they store the GLB files?
They don't know how to generate thumbnails — they need preview images
They don't have a fallback — if Tripo fails, they have no backup

3D API integration and evaluation (Chamfer distance, geometric accuracy) demonstrates you can build production 3D generation systems, not just call APIs.

What you'll build
Integrate Tripo API and Rodin API for programmatic 3D generation. Evaluate 3D model quality (mesh quality, texture fidelity, Chamfer distance). Implement 3D model hosting and delivery (CDN, format conversion, thumbnails).
