Unity API 返回 Vector3，但值错误

问：

我正在使用 Replicate API 尝试在 Unity 中获取点云。我终于让 API 返回一个 JSON 文件，我很确定它返回了每个点的位置。然而，当我将其转换为 vector3 时，这些值变得异常，每个数字都类似于 6.852349e-43，甚至一些“NaN”，在 API 上它们似乎都是低于 0 的值。vector3

这是它们在 Replicate 页面上的样子，

  "coords": [
    [
      -0.039118800312280655,
      -0.25740715861320496,
      0.28050559759140015
    ],
    [
      0.13176295161247253,
      0.23972494900226593,
      -0.06013050675392151
    ],

然而，当我在 Unity 中将它们转换为 a 时，它们像这样返回，我假设我不应该将它们转换为 ？Replicate 的页面显示“坐标”是 （X，Y，Z） 点坐标的 [N x 3] 数组“，经过广泛的谷歌搜索，我不知道 NX3 是什么意思。我试过 ， ， 而不是 ，但是唯一一个从 JSON 文件中正确分配的，（使用vector3vector3float[,]float[,,]float[][]vector3vector3JsonUtility.FromJson)

这是我调用 api 的脚本，

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Networking;
using SimpleJSON;

public class Prompt
{
    public string prompt;
}

public class PostResponse
{

    public string completed_at;
    public string created_at;
    public string error;
    public string id;

    public string[] logs;
    public string metrics;
    public Output output;

    public string status;
    public string version;

}

public class ReplicateAPI : MonoBehaviour
{
    private string API_ENDPOINT = "https://api.replicate.com/v1/predictions";
    private string REPLICATE_API_TOKEN = "r8_DhOE6C7LuA7edPvLh7Io0ukwbmXCLEY450vc3";

    [SerializeField] PointEResponse response;

    public string prompt = "dog";

    [SerializeField] Material material;

    [SerializeField] MeshFilter meshFilter;

    private void Start()
    {
        StartCoroutine(Predict());
    }

    IEnumerator Predict()
    {
        string requestData = $@"{{
    ""version"": ""1a4da7adf0bc84cd786c1df41c02db3097d899f5c159f5fd5814a11117bdf02b"",
    ""input"": {{
        ""prompt"": ""{prompt}"",
        ""output_format"": ""json_file""
    }}
}}";

        UnityWebRequest request = UnityWebRequest.Put(API_ENDPOINT, requestData);
        request.method = "POST";
        request.SetRequestHeader("Authorization", "Token " + REPLICATE_API_TOKEN);
        request.SetRequestHeader("Content-Type", "application/json");


        yield return request.SendWebRequest();

        if (request.result == UnityWebRequest.Result.ConnectionError || request.result == UnityWebRequest.Result.ProtocolError)
        {
            Debug.LogError("Error " + request.responseCode + ": " + request.error);
            StartCoroutine(Predict());
        }
        else
        {
            Debug.Log(request.downloadHandler.text);
            PostResponse response = JsonUtility.FromJson<PostResponse>(request.downloadHandler.text);

            StartCoroutine(GetResult(response.id));
        }
    }

    IEnumerator GetResult(string id)
    {
        yield return new WaitForSeconds(5);
        UnityWebRequest request = UnityWebRequest.Get(API_ENDPOINT + "/" + id);
        request.SetRequestHeader("Authorization", "Token " + REPLICATE_API_TOKEN);
        request.SetRequestHeader("Content-Type", "application/json");



        yield return request.SendWebRequest();

        if (request.result == UnityWebRequest.Result.ConnectionError || request.result == UnityWebRequest.Result.ProtocolError)
        {
            Debug.LogError("Error " + request.responseCode + ": " + request.error);
            yield break;
        }
        else
        {
            response = JsonUtility.FromJson<PointEResponse>(request.downloadHandler.text);



            Debug.Log(request.downloadHandler.text);
        }

        if (response.status != "succeeded") StartCoroutine(GetResult(id));
        else
        {

            if (response.output.json_file.colors != null && response.output.json_file.colors.Length > 0)
            {

                for (int i = 0; i < response.output.json_file.colors.Length; i++)
                {

                    GameObject g = GameObject.CreatePrimitive(PrimitiveType.Sphere);
                    g.transform.localScale = Vector3.one / 100;
                    g.transform.position = new Vector3(response.output.json_file.coords[i].x, response.output.json_file.coords[i].y, response.output.json_file.coords[i].z);
                    Material m = new Material(material);
                    m.color = new Color(response.output.json_file.colors[i].x, response.output.json_file.colors[i].y, response.output.json_file.colors[i].z);
                    g.GetComponent<MeshRenderer>().material = m;
                }

            }
            else
            {
                StartCoroutine(GetResult(id));
            }
        }
    }

}

“response”类如下所示，

using System;
using UnityEngine;

[Serializable]
public class PointEResponse
{
    public string id;
    public string version;
    public Urls urls;
    public DateTime created_at;
    public DateTime started_at;
    public DateTime completed_at;
    public string source;
    public string status;
    public Prompt input;
    public Output output;
    public object error;
    public string[] logs;
    public Metrics metrics;
}

[Serializable]
public class Output
{
    public JsonFile json_file;
}

[Serializable]
public class JsonFile
{
    public Vector3[] coords;
    public Vector3[] colors;

}

public class Urls
{
    public string get;
    public string cancel;
}

public class Metrics
{
    public float predict_time;
}

其中输出包含每个坐标的坐标和颜色。我假设我不应该将这些转换为 Vector3，但我已经尝试了我所知道的所有其他方法，其中唯一一个甚至返回任何形式的。

如何解决此问题？
