クイックスタート

# クイックスタート Tripo API を 15 分で使い始めて、最初の 3D モデルを最初から生成します。 ## 1. API Key を入手する [Tripo コンソール](https://platform.tripo3d.ai) に移動し、アカウントを作成し、「API Keys」ページを開いて API Key を作成します。 ## 2. 最初のリクエストを送信します テキストの説明から 3D モデルを生成します。 ### curl ```bash curl -X POST https://openapi.tripo3d.ai/v3/generation/text-to-model \ -H "Content-Type: application/json" \ -H "Authorization: Bearer {api_key}" \ -d '{ "prompt": "a cute cat", "model": "tripo-v3.1" }' ``` 成功の応答: ```json { "code": 0, "data": { "task_id": "task_abc123" } } ``` ## 3. タスクの結果をクエリする 3D 生成は非同期タスクとして実行されます。返された `task_id` を使用して、タスクのステータスをポーリングします。 ```bash curl -X GET https://openapi.tripo3d.ai/v3/tasks/task_abc123 \ -H "Authorization: Bearer {api_key}" ``` `status` が `success` になると、タスクは完了です。 ```json { "code": 0, "data": { "task_id": "task_abc123", "type": "text_to_model", "status": "success", "progress": 100, "output": { "model_url": "https://...", "rendered_image_url": "https://..." } } } ``` ## 4. モデルをダウンロードする 応答内の `output.model_url` から GLB 3D モデル ファイルをダウンロードします。 Blender、Unity、Three.js などのツールで直接使用できます。 ## 完全な例 ### Python ```python import time import requests API_KEY = "your_api_key_here" BASE_URL = "https://openapi.tripo3d.ai/v3" headers = { "Content-Type": "application/json", "Authorization": f"Bearer {API_KEY}" } # 1. Create a text-to-3D task response = requests.post( f"{BASE_URL}/generation/text-to-model", headers=headers, json={ "prompt": "a cute cat", "model": "tripo-v3.1" } ) task_id = response.json()["data"]["task_id"] print(f"Task created: {task_id}") # 2. Poll until the task is complete while True: response = requests.get( f"{BASE_URL}/tasks/{task_id}", headers={"Authorization": f"Bearer {API_KEY}"} ) task = response.json()["data"] status = task["status"] progress = task.get("progress", 0) print(f"Status: {status}, progress: {progress}%") if status == "success": model_url = task["output"]["model_url"] print(f"Model download URL: {model_url}") break elif status in ("failed", "cancelled", "banned"): print(f"Task failed: {status}") break time.sleep(2) # 3. Download the model file if status == "success": model_data = requests.get(model_url) with open("model.glb", "wb") as f: f.write(model_data.content) print("Model saved as model.glb") ``` ### JavaScript ```javascript const API_KEY = "your_api_key_here"; const BASE_URL = "https://openapi.tripo3d.ai/v3"; async function generateModel() { // 1. Create a text-to-3D task const createResponse = await fetch(`${BASE_URL}/generation/text-to-model`, { method: "POST", headers: { "Content-Type": "application/json", "Authorization": `Bearer ${API_KEY}` }, body: JSON.stringify({ prompt: "a cute cat", model: "tripo-v3.1" }) }); const { data: { task_id } } = await createResponse.json(); console.log(`Task created: ${task_id}`); // 2. Poll until the task is complete while (true) { const pollResponse = await fetch(`${BASE_URL}/tasks/${task_id}`, { headers: { "Authorization": `Bearer ${API_KEY}` } }); const { data: task } = await pollResponse.json(); const { status, progress = 0 } = task; console.log(`Status: ${status}, progress: ${progress}%`); if (status === "success") { console.log(`Model download URL: ${task.output.model_url}`); return task.output; } if (["failed", "cancelled", "banned"].includes(status)) { throw new Error(`Task failed: ${status}`); } await new Promise(resolve => setTimeout(resolve, 2000)); } } generateModel().catch(console.error); ```
