How to Use AI 3D Model Generation API: Text & Image to 3D (2026)

How to Use AI 3D Model Generation API

AI 3D generation has crossed a tipping point. You can now generate production-ready 3D models from a text prompt or a single image in under 30 seconds via API. No 3D modeling skills required.

This guide covers the best 3D generation APIs, how to use them, and practical applications.

What Can AI 3D Generation APIs Do?

• Text to 3D — describe an object, get a textured 3D model
• Image to 3D — upload a photo, get a 3D mesh with textures
• 3D reconstruction — convert multiple photos into a 3D scene
• Texture generation — generate or change textures on existing 3D models
• 3D animation — add basic animations to generated models

Best 3D Generation APIs (2026)

All models above are available through Hypereal AI's unified API.

Step-by-Step: Generate 3D Models via API

Image to 3D (Most Common)

import hypereal

client = hypereal.Client(api_key="YOUR_API_KEY")

# Generate a 3D model from a product photo
model_3d = client.generate_3d(
    model="triposr-2",
    image_url="https://example.com/product-photo.jpg",
    output_format="glb",
    texture_resolution=1024
)

print(f"3D Model URL: {model_3d.model_url}")
print(f"Thumbnail: {model_3d.thumbnail_url}")
print(f"Vertices: {model_3d.vertex_count}")

Text to 3D

model_3d = client.generate_3d(
    model="rodin-gen-2",
    prompt="a low-poly medieval castle with stone walls and a red flag on top",
    output_format="glb",
    style="realistic"  # realistic, cartoon, low-poly
)

Batch Processing

import asyncio

products = [
    "https://store.com/photos/shoe-001.jpg",
    "https://store.com/photos/shoe-002.jpg",
    "https://store.com/photos/bag-001.jpg",
]

async def generate_3d_batch(images):
    tasks = [
        client.generate_3d(
            model="triposr-2",
            image_url=img,
            output_format="glb"
        )
        for img in images
    ]
    return await asyncio.gather(*tasks)

models = asyncio.run(generate_3d_batch(products))

Use Cases

E-Commerce 3D Product Viewers

Let customers rotate and inspect products in 3D:

<!-- Embed the generated GLB model in a web page -->
<model-viewer
  src="https://cdn.hypereal.ai/models/product-abc123.glb"
  alt="3D product view"
  auto-rotate
  camera-controls
  ar
  style="width: 100%; height: 400px;">
</model-viewer>

<script type="module" src="https://ajax.googleapis.com/ajax/libs/model-viewer/3.0/model-viewer.min.js"></script>

Game Asset Generation

Generate game-ready assets from concept art:

asset = client.generate_3d(
    model="rodin-gen-2",
    image_url="https://example.com/concept-art/sword.jpg",
    output_format="fbx",
    optimize_for="game",  # Reduces poly count
    max_vertices=10000
)

AR/VR Applications

Generate 3D objects for augmented reality:

ar_model = client.generate_3d(
    model="triposr-2",
    image_url="https://example.com/furniture/chair.jpg",
    output_format="usdz",  # Apple AR format
    texture_resolution=2048
)

Tips for Best Results

1. Clean input images — remove background before processing for better geometry
2. Front-facing photos — straight-on product photos produce the best 3D models
3. Good lighting — evenly lit subjects generate better textures
4. Specify output format — GLB for web, FBX for Unity/Unreal, USDZ for Apple AR
5. Optimize poly count — specify max vertices for real-time applications
6. Post-process textures — AI-generated textures sometimes need manual touch-ups
