unity3d摄像机输出图片

可以使用Unity3D中的RenderTexture来实现摄像机输出图片的功能。首先创建一个RenderTexture，然后将摄像机的Target Texture设置为该RenderTexture，最后使用Graphics.Blit函数将RenderTexture中的图像渲染到一个Texture2D中，即可得到摄像机输出的图片。

unity3d摄像机输出图片代码

以下是 Unity3D 摄像机输出图片的代码示例：

using UnityEngine;

public class CameraCapture : MonoBehaviour
{
    public Camera cameraToCapture;
    public string savePath = "Assets/CapturedImage.png";

    void Update()
    {
        if (Input.GetKeyDown(KeyCode.Space))
        {
            Capture();
        }
    }

    void Capture()
    {
        RenderTexture renderTexture = cameraToCapture.targetTexture;
        Texture2D texture = new Texture2D(renderTexture.width, renderTexture.height, TextureFormat.RGB24, false);
        cameraToCapture.Render();
        RenderTexture.active = renderTexture;
        texture.ReadPixels(new Rect(0, 0, renderTexture.width, renderTexture.height), 0, 0);
        texture.Apply();
        RenderTexture.active = null;
        byte[] bytes = texture.EncodeToPNG();
        System.IO.File.WriteAllBytes(savePath, bytes);
        Debug.Log("Image captured and saved to " + savePath);
    }
}

这段代码可以让你在 Unity3D 中捕获摄像机的输出图像，并将其保存为 PNG 图片。你可以将其添加到一个空对象上，并将需要捕获的摄像机指定为 `cameraToCapture` 变量。按下空格键即可触发捕获操作。

unity3d摄像机输出模型图片代码

以下是我对您的问题的回答：

您可以使用以下代码将 Unity3D 摄像机输出模型图片：

using UnityEngine;
using System.Collections;

public class CameraScreenshot : MonoBehaviour {

    public int captureWidth = 1920;
    public int captureHeight = 1080;

    private bool capturingScreenshot = false;

    void Update () {
        if (Input.GetKeyDown(KeyCode.Space)) {
            capturingScreenshot = true;
        }
    }

    void LateUpdate () {
        if (capturingScreenshot) {
            capturingScreenshot = false;

            RenderTexture rt = new RenderTexture(captureWidth, captureHeight, 24);
            GetComponent<Camera>().targetTexture = rt;
            Texture2D screenShot = new Texture2D(captureWidth, captureHeight, TextureFormat.RGB24, false);
            GetComponent<Camera>().Render();
            RenderTexture.active = rt;
            screenShot.ReadPixels(new Rect(0, 0, captureWidth, captureHeight), 0, 0);
            GetComponent<Camera>().targetTexture = null;
            RenderTexture.active = null; // JC: added to avoid errors
            Destroy(rt);
            byte[] bytes = screenShot.EncodeToPNG();
            string filename = Application.dataPath + "/../screenshot.png";
            System.IO.File.WriteAllBytes(filename, bytes);
            Debug.Log(string.Format("Took screenshot to: {0}", filename));
        }
    }
}

这段代码会在按下空格键时，将当前摄像机的渲染结果保存为一张 PNG 格式的图片，并保存在应用程序的根目录下。您可以根据需要修改图片的分辨率和保存路径。
