XNA則是透過座標以及一些方框去接收，透過Draw方法將影像描繪出來

在Kinect影像事件觸發時，將資料塞入Texture2D物件，透過Rectangle指定初始位址以及寬高
void kinect_ColorFrameReady(object sender, ColorImageFrameReadyEventArgs e)
{
using (ColorImageFrame frame = e.OpenColorImageFrame())
{
if (frame == null)
return;
dataPixels = new byte[frame.PixelDataLength];
frame.CopyPixelDataTo(dataPixels);
texture2D = new Texture2D(GraphicsDevice, 640, 480);
texture2D.SetData(dataPixels);
}
}執行結果：
影像色澤偏藍可以參閱『Kinect+XNA彩色資訊』文章，裡面提到Kinect採用『BGRA』格式，而XNA採用『RGBA』格式
因此將BGRA轉RGBA就不會在出現藍藍的影像
改一下『kinect_ColorFrameReady』方法
void kinect_ColorFrameReady(object sender, ColorImageFrameReadyEventArgs e)
{
using (ColorImageFrame frame = e.OpenColorImageFrame())
{
if (frame == null)
return;
dataPixels = new byte[frame.PixelDataLength];
frame.CopyPixelDataTo(dataPixels);
Color[] colors = new Color[frame.Width * frame.Height];
int sourceOffset = 0;
int colorsLength = colors.Length;
for (int index = 0; index < colorsLength; index++)
{
colors[index] = new Color(dataPixels[sourceOffset + 2],
dataPixels[sourceOffset + 1], dataPixels[sourceOffset], 255);
sourceOffset += 4;
}
texture2D = new Texture2D(GraphicsDevice, 640, 480);
texture2D.SetData(colors);
}
}
