Unity-显示Kinect深度数据

设置为如下参数，将其设定为unlit-transparent使得透明显示

    public MultiSourceManager mMultiSource;
    public Texture2D mDepthTexture;//深度纹理

    //深度数据
    private ushort[] mDepthData = null;//MultiSource Manager输出的深度数据内容
    private CameraSpacePoint[] mCameraSpacePoint = null;
    private ColorSpacePoint[] mColorSpacePoints = null;

    //Kinect
    private KinectSensor mSensor = null;
    private CoordinateMapper mMapper = null;//映射坐标器

    //深度数据的分辨率为512*424
    private readonly Vector2 mDepthResolution = new Vector2(512, 424);

private void Awake()
    {
        mSensor = KinectSensor.GetDefault();//获取Kinect传感器
        mMapper = mSensor.CoordinateMapper;//获取坐标映射器

        int arraySize = (int)(mDepthResolution.x * mDepthResolution.y);//深度数据分辨率

        //根据深度数据的分辨率创建新的空间点
        mCameraSpacePoint = new CameraSpacePoint[arraySize];
        mColorSpacePoints = new ColorSpacePoint[arraySize];
    }

    private void Update()
    {
        if (Input.GetKeyDown(KeyCode.Space))//判断是否按下空格
        {
            //按下空格则将深度图像映射到彩色空间
            DepthToColor();
            mDepthTexture = CreateTexture();//获取新纹理
        }
    }

    /// 

    /// 创建新纹理
    /// 
    /// 
    private Texture2D CreateTexture()
    {
        Texture2D newTexture = new Texture2D(1920, 1080, TextureFormat.Alpha8, false);//RGB相机输出的1920*1080像素的图片，alpha8使我们能看到透明的图片
        
        //遍历所有像素点清除初始纹理
        for (int x = 0; x < 1920; x++)
        {
            for (int y = 0; y < 1080; y++)
            {
                newTexture.SetPixel(x, y, Color.clear);
            }
        }
        //遍历所有像素点为他们设置新的颜色
        foreach (ColorSpacePoint point in mColorSpacePoints)//遍历所有像素点为他们设置新的颜色
        {
            newTexture.SetPixel((int)point.X, (int)point.Y, Color.black);

        }
        newTexture.Apply();//应用新纹理
        return newTexture;
    }

	/// 

    /// 获取相机空间点和颜色空间点
    /// 
    private void DepthToColor()
    {
        //获取深度图像数据，一组数据流
        mDepthData = mMultiSource.GetDepthData();

        //将图像映射
        mMapper.MapDepthFrameToCameraSpace(mDepthData, mCameraSpacePoint);//将深度帧数映射到相机空间点
        mMapper.MapDepthFrameToColorSpace(mDepthData, mColorSpacePoints);//深度帧数映射到颜色空间点
    }

清除彩色图像后能显示出如下的深度数据。
