本文通过参考网上资源做的一个例子。
本程序的功能就是通过xna 将3d 图像显示到winfrom 对他进行旋转操作。
首先我们先准备好两个文件夹
model 文件夹放fbx文件，textures 放渲染文件，操作步骤都是添加现有项，准备好资源文件后，先检查下是否有以下引用
下面将定义Game类的实现方法

然后进行 winfrom 的编写
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.IO;
using System.Linq;
using System.Reflection;
using System.Text;
using System.Threading;
using System.Windows.Forms;
namespace _3DModel
{
public partial class MainForm : Form
{
public MainForm()
{
InitializeComponent();
}
//xna form 接入
public Control Panel
{
get { return XnaPanel; }
}
public string strRotate="";
private void bt_Up_MouseDown(object sender, MouseEventArgs e)
{
Button bt = (Button)sender;
strRotate = bt.Text;
timer1.Enabled = true;
}
private void bt_Up_MouseUp(object sender, MouseEventArgs e)
{

timer1.Enabled = false ;
}
private void timer1_Tick(object sender, EventArgs e)
{if(strRotate =="Up")
Program.modelRotationX += (float)(-0.03);
else if(strRotate =="Down")
Program.modelRotationX -= (float)(-0.03);
else if (strRotate == "Left")
Program.modelRotationY -= (float)(-0.03);
else if (strRotate == "Right")

}
private void bt_Left_Click(object sender, EventArgs e)
{
}
public static MainForm form;
static Game1 game=new Game1(form);
public void button1_Click(object sender, EventArgs e)
{
OpenFileDialog fileDialog = new OpenFileDialog();
game.Exit();
fileDialog.Title = "Load Model";
fileDialog.Filter = "Model Files (*.fbx;*.x)|*.fbx;*.x|" +
"FBX Files (*.fbx)|*.fbx|" +
"X Files (*.x)|*.x|" +
"All Files (*.*)|*.*";
if (fileDialog.ShowDialog() == DialogResult.OK)
{
string[] strName = fileDialog.SafeFileName.Split('.');
filename = strName[0];
game.loade();
}
}
public string filename = "1";
}
}
效果如下
