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,如下面的视频所示: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
};

处理 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.这里的构造函数.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,请参阅此处的github示例

如上所述,渲染到WindowsForm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. 在Form类:在这里我们做设备,交换链,渲染目标和渲染目标视图中的一个变量Form,我们声明类

   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.
