Prerequisites

  • Create an API Key from the Eachlabs Console
  • Install the required dependencies for your chosen language (e.g., requests for Python)

API Integration Steps

1. Create a Prediction

Send a POST request to create a new prediction. This will return a prediction ID that you'll use to check the result. The request should include your model inputs and API key.

import requests
import time


API_KEY = "YOUR_API_KEY"  # Replace with your API key
HEADERS = {
    "X-API-Key": API_KEY,
    "Content-Type": "application/json"
}


def create_prediction():
    response = requests.post(
        "https://api.eachlabs.ai/v1/prediction/",
        headers=HEADERS,
        json={
            "model": "tencent-hunyuan-3d-2",
            "version": "Hunyuan3D-DiT-v2-0-Fast",
            "input": {
  "seed": 1234,
  "guidance_scale": 5.5,
  "octree_resolution": 256,
  "remove_background": false,
  "inference_steps": 20,
  "shape_only": false,
  "prompt": "your prompt here",
  "task": "text-to-3d"
}
        }
    )
    prediction = response.json()
    
    if prediction["status"] != "success":
        raise Exception(f"Prediction failed: {prediction}")
    
    return prediction["predictionID"]

2. Get Prediction Result

Poll the prediction endpoint with the prediction ID until the result is ready. The API uses long-polling, so you'll need to repeatedly check until you receive a success status.

def get_prediction(prediction_id):
    while True:
        result = requests.get(
            f"https://api.eachlabs.ai/v1/prediction/{prediction_id}",
            headers=HEADERS
        ).json()
        
        if result["status"] == "success":
            return result
        elif result["status"] == "error":
            raise Exception(f"Prediction failed: {result}")
        
        time.sleep(1)  # Wait before polling again

3. Complete Example

Here's a complete example that puts it all together, including error handling and result processing. This shows how to create a prediction and wait for the result in a production environment.

try:
    # Create prediction
    prediction_id = create_prediction()
    print(f"Prediction created: {prediction_id}")
    
    # Get result
    result = get_prediction(prediction_id)
    print(f"Output URL: {result['output']}")
    print(f"Processing time: {result['metrics']['predict_time']}s")
except Exception as e:
    print(f"Error: {e}")

Additional Information

  • The API uses a two-step process: create prediction and poll for results
  • Response time: ~300 seconds
  • Rate limit: 60 requests/minute
  • Concurrent requests: 10 maximum
  • Use long-polling to check prediction status until completion

Overview

Tencent's Hunyuan 3D-2 is an advanced AI model designed to generate high-resolution 3D assets from textual or image inputs. It supports both text-to-3D and image-to-3D tasks, enabling users to create detailed 3D models efficiently.

Technical Specifications

Architecture: Hunyuan 3D-2 utilizes large-scale diffusion models to generate high-resolution 3D assets. The Tencent Hunyuan 3D-2 has been optimized to reduce inference time while maintaining quality, achieving a balance between speed and detail.

Performance: The Tencent Hunyuan 3D-2 achieves a CLIP score of 0.809, surpassing both open-source and proprietary alternatives. It introduces significant improvements in texture synthesis and geometric accuracy, outperforming existing solutions across standard industry metrics.

Key Considerations

Input Quality: The quality of the generated 3D model is heavily influenced by the clarity and detail of the input prompt or image. Ensure inputs are well-prepared to achieve the best results.

Output Formats: The generated 3D models are typically output in formats compatible with standard 3D software. Verify that the output format aligns with your intended use case.

Tips & Tricks

  • Prompt:
    • For text-to-3D: Use specific and detailed descriptions, including attributes like size, shape, material, and context. For example, "A medieval wooden bridge over a flowing river with stone pillars."
    • For image-to-3D: Ensure the image has a transparent background and clearly depicts the subject to facilitate accurate 3D reconstruction.
  • Task:
    • Select 'text-to-3D' when providing a textual description as input.
    • Select 'image-to-3D' when using an image as the input source.
  • Shape Only:
    • Enable this option if you require only the geometric structure of the Tencent Hunyuan 3D-2 without textures. This is beneficial for applications focusing on form rather than appearance.
  • Inference Steps:
    • Set the inference steps between 20 to 50 based on the desired detail level and available computational resources. Higher steps result in more detailed models but require more processing time.

Capabilities

  • Rapid Prototyping: Quickly generate 3D models for concept visualization in design and development processes.
  • Educational Purposes: Aid in teaching 3D modeling concepts by providing quick examples based on textual or image descriptions.
  • Creative Projects: Assist artists and creators in developing 3D assets for various media, including games and animations.
