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)
| Model | Input | Quality | Speed | Price | Output Format |
|---|---|---|---|---|---|
| TripoSR 2.0 | Image | Very Good | 10-20s | $0.05 | GLB, OBJ |
| Rodin Gen-2 | Text + Image | Excellent | 30-60s | $0.10 | GLB, FBX |
| Hunyuan3D 2.5 | Text + Image | Very Good | 20-40s | $0.08 | GLB, OBJ |
| Tripo3D | Image | Good | 15-30s | $0.06 | GLB |
| Meshy | Text + Image | Good | 60-120s | $0.10 | GLB, FBX, OBJ |
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
- Clean input images — remove background before processing for better geometry
- Front-facing photos — straight-on product photos produce the best 3D models
- Good lighting — evenly lit subjects generate better textures
- Specify output format — GLB for web, FBX for Unity/Unreal, USDZ for Apple AR
- Optimize poly count — specify max vertices for real-time applications
- Post-process textures — AI-generated textures sometimes need manual touch-ups
Why Hypereal AI for 3D Generation
- Multiple 3D models: TripoSR, Rodin, Hunyuan3D, Tripo3D — pick the best one for your use case
- One API: Same API key as your image and video generation
- Multiple output formats: GLB, OBJ, FBX, USDZ
- Pay-per-model: $0.05-0.10 per 3D model, no subscription
- Fast: 10-60 seconds depending on model and complexity
- No restrictions: Generate any type of 3D content
Conclusion
AI 3D generation APIs are making it possible for any developer to add 3D capabilities to their products. From e-commerce product viewers to game assets, the technology is fast, affordable, and accessible.
