SharpDX：如何在Winforms窗口中放置SharpDX窗口？

Question

我实际上是试着将SharpDX Window放在Winforms窗口中，如下面的视频：http://www.youtube.com/watch?v=g-JupOxwB-k

在SharpDX中，这种方法不起作用。任何人都可以告诉我如何轻松地做到这一点？

不要认为它是一个sharpDX窗口进入winforms窗口。

而是将其视为如何将SharpDX输出到Windows句柄（sorta）

关键是SharpDX.DXGI.SwapChain。创建时，您需要一个SwapChainDescription

我喜欢创造我的喜欢

SwapChainDescription scd = new SwapChainDescription()
{
  //set other fields
  OutputHandle = yourform.Handle,
  //set other fields
};

Handle SwapChainDescription

因此，当您调用SwapChain.Present（）时，它将呈现给表单。

这是使用直接SharpDX而不是工具包的基本方法

如果要使用工具包的GraphicsDevice，则必须设置Presenter属性。 constructor here。几乎与在演示参数中设置窗口句柄的方式相同。 DeviceWindowHandle

此工具包还有RenderForm，可以与Game类配合使用

编辑（DirectX示例）

这是一个使用直接SharpDX（No Toolkit）的例子。有关完整示例，请参阅github示例HERE

如上所述，渲染到Windows窗体窗口所需要做的就是将Handle传递给SwapChain

1. 添加引用:(所有其他引用都是默认的winforms项目引用）

2. 一些使用语句使事情变得更容易：

     namespace YourNameSpaceHere
     {
         using Device = SharpDX.Direct3D11.Device;
   
         using Buffer = SharpDX.Direct3D11.Buffer;
   
         ...the rest of the application
     } 

3. Form类：这里我们创建设备，交换链，渲染目标，并渲染目标视图我们声明的Form类的变量

   public partial class Form1 : Form //default vs2012 declaration
   {
       Device d;                   //Direct311
       SwapChain sc;               //DXGI
   
       Texture2D target;           //Direct3D11
       RenderTargetView targetveiw;//DIrect3D11
   
       ...the rest of the form
   
   }       

4. 初始化Device和SwapChain：这对我的系统起作用。如果您遇到问题，则需要研究具体的实施和硬件。 DirectX（以及扩展名SharpDX）提供了一些方法，您可以通过这些方法检测硬件将支持的内容。

主要代码示例：

using System;

using System.ComponentModel;//needed to overide OnClosing
//I removed useless usings
using System.Windows.Forms;

using SharpDX.Direct3D11;
using SharpDX.DXGI;
using SharpDX;


namespace WindowsFormsApplication2
{
using Device = SharpDX.Direct3D11.Device;
using Buffer = SharpDX.Direct3D11.Buffer;


public partial class Form1 : Form
{
    Device d;
    SwapChain sc;

    Texture2D target;
    RenderTargetView targetveiw;       

    public Form1()
    {
        InitializeComponent();

        SwapChainDescription scd = new SwapChainDescription()
        {
            BufferCount = 1,                                 //how many buffers are used for writing. it's recommended to have at least 2 buffers but this is an example
            Flags = SwapChainFlags.None,
            IsWindowed = true,                               //it's windowed
            ModeDescription = new ModeDescription(
                this.ClientSize.Width,                       //windows veiwable width
                this.ClientSize.Height,                      //windows veiwable height
                new Rational(60,1),                          //refresh rate
                Format.R8G8B8A8_UNorm),                      //pixel format, you should resreach this for your specific implementation

            OutputHandle = this.Handle,                      //the magic 

            SampleDescription = new SampleDescription(1, 0), //the first number is how many samples to take, anything above one is multisampling.
            SwapEffect = SwapEffect.Discard,
            Usage = Usage.RenderTargetOutput
        };

        Device.CreateWithSwapChain(
            SharpDX.Direct3D.DriverType.Hardware,//hardware if you have a graphics card otherwise you can use software
            DeviceCreationFlags.Debug,           //helps debuging don't use this for release verion
            scd,                                 //the swapchain description made above
            out d, out sc                        //our directx objects
            );

        target = Texture2D.FromSwapChain<Texture2D>(sc, 0);
        targetveiw = new RenderTargetView(d, target);

        d.ImmediateContext.OutputMerger.SetRenderTargets(targetveiw);

    }

    protected override void OnClosing(CancelEventArgs e)
    {
        //dipose of all objects
        d.Dispose();
        sc.Dispose();
        target.Dispose();
        targetveiw.Dispose();

        base.OnClosing(e);
    }

    protected override void OnPaint(PaintEventArgs e)
    {
        //I am rendering here for this example
        //normally I use a seperate thread to call Draw() and Present() in a loop
        d.ImmediateContext.ClearRenderTargetView(targetveiw, Color.CornflowerBlue);//Color to make it look like default XNA project output.
        sc.Present(0, PresentFlags.None);

        base.OnPaint(e);
    }

}
}

这是为了让您开始在托管环境中使用ShaprDX使用DirectX，特别是在Windows上使用C＃。你需要更多的东西来获得真实的东西。这意味着使用SharpDX在Winforms窗口上渲染的网关。我不解释像顶点/索引缓冲区或渲染纹理/精灵这样的东西。因为它超出了问题的范围。
