Setup

On first use, ensure the NEURAL4D_API_TOKEN environment variable is set.
All API requests must include the header: Authorization: Bearer <YOUR_TOKEN>.

When to Use

Use this skill when generating 3D models from text prompts or images using DreamTech's Neural4D engine. This is particularly suited for creating assets where precise format conversions (like .stl, .obj, .fbx) and physical dimensions are required for manufacturing workflows.

Core Rules & Cost Guardrails

1. Point Consumption Awareness

Always track API point costs before executing bulk runs:

• - Text to 3D: 20 points per operation.
• Image to 3D: 20 points per operation.
• Chibi-style Generation: 30 points per operation.
• Format Conversion: 10 points per operation.
• You can query the remaining balance at /api/queryPointsInfo.

2. Asynchronous Polling Contract

Model generation is asynchronous. You must poll for completion:

• - Query /api/retrieveModel using the uuid.
• Check codeStatus:

- 0: Generation complete. - 1: Generating (Wait and poll again). - -3: Generation failed.

Workflow Pipelines

Pipeline A: Text to 3D

1. 1. Request: POST https://alb.neural4d.com:3000/api/generateModelWithText.

- Payload: {"prompt": "...", "modelCount": 4, "disablePbr": 0}.

1. 2. Retrieve: Extract uuids from the response.
2. Poll: Call /api/retrieveModel with the uuid until codeStatus is 0.
3. Download: Extract modelUrl and download the .glb asset.

Pipeline B: Image to 3D (Strict 3-Step Process)

1. 1. Matting: Submit the image (JPG/PNG, <10MB, 256x256 to 6048x8064) via multipart/form-data to /api/mattingImage. Extract the requestId.
2. Get Matting Result: Send the requestId to /api/getMattedResult. Extract a preferred fileKey from the response.
3. Generate: Send the fileKey to /api/generateModelWithImage to start generation and receive uuids.
4. Poll: Use /api/retrieveModel to poll status and get the modelUrl.

Pipeline C: Format Conversion for Manufacturing

For physical prototyping, default exports must be converted from .glb.

1. 1. Request: POST https://alb.neural4d.com:3000/api/convertToFormat.
2. Payload: Provide the uuid, desired modelType (e.g., stl, fbx, obj), and modelSize in millimeters (must be > 1).
3. Poll Status: Check statusType:

- 0: Complete, use modelUrl to download. - 1: Converting (Wait and retry). - -1: Failed or bad parameters.
