该模型是 .fbx 我也尝试了许多模型，似乎没有任何效果我想知道是否有人可以帮助我，以下代码是我所拥有的一切，谢谢！

using System;
using System.Collections.Generic;
using System.Linq;
using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Audio;
using Microsoft.Xna.Framework.Content;
using Microsoft.Xna.Framework.GamerServices;
using Microsoft.Xna.Framework.Graphics;
using Microsoft.Xna.Framework.Input;
using Microsoft.Xna.Framework.Media;

namespace _3D
{

    public class Game1 : Microsoft.Xna.Framework.Game
    {
        GraphicsDeviceManager graphics;
        SpriteBatch spriteBatch;
        Model model;
        Matrix[] transforms;

        public Game1()
        {
            graphics = new GraphicsDeviceManager(this);
            Content.RootDirectory = "Content";
            graphics.PreferredBackBufferHeight = 800;
            graphics.PreferredBackBufferWidth = 1280;
        }

        protected override void Initialize()
        {

            base.Initialize();
        }

        protected override void LoadContent()
        {
            spriteBatch = new SpriteBatch(GraphicsDevice);
            model = Content.Load<Model>("3d/screwdriver");
            transforms = new Matrix[model.Bones.Count];
            model.CopyAbsoluteBoneTransformsTo(transforms);
        }
        protected override void UnloadContent()
        {
        }


        protected override void Update(GameTime gameTime)
        {

            if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed)
                this.Exit();


            base.Update(gameTime);
        }    

        // The draw method is one of the reasons I think nothing is working,

        protected override void Draw(GameTime gameTime)
        {
            GraphicsDevice.Clear(Color.CornflowerBlue);
            Matrix view = Matrix.CreateLookAt(
                new Vector3(200, 300, 900),
                new Vector3(0, 50, 0),
                Vector3.Up);
            Matrix projection = Matrix.CreatePerspectiveFieldOfView(MathHelper.ToRadians(45), GraphicsDevice.Viewport.AspectRatio, 0.1f, 10000.0f);
            Matrix baseWorld = Matrix.CreateScale(0.4f) * Matrix.CreateRotationY(MathHelper.ToRadians(180));
            foreach (ModelMesh mesh in model.Meshes)
            {
                Matrix localWorld = transforms[mesh.ParentBone.Index] * baseWorld;
                foreach (ModelMeshPart part in mesh.MeshParts)
                { 
                BasicEffect e = (BasicEffect)part.Effect;
                e.World = localWorld;
                e.View = view;
                e.Projection = projection;
                e.EnableDefaultLighting();

                }
                mesh.Draw();
            }
            base.Draw(gameTime);
        }
    }
}

我看不出你的代码有什么问题，所以问题可能出在模型上。

这可能是由有问题的模型文件引起的。Blender 上的库存 FBX Exporter 存在一个已知问题（我不知道您用于制作模型的建模软件，但问题仍然相关），这使得模型导出的尺寸比原来大 100 倍搅拌机。结果是模型如此之大，以至于它不仅将相机封闭在其内部，而且如此之大，以至于它的多边形超出了视锥体。结果：模型确实被渲染了，但它永远不会出现在屏幕上，除非你移动相机直到你意识到缩放问题。

我这么说是因为我自己处理过这个问题。如果您确实在使用 Blender，则应使用此页面中的导出器： http ://blog.diabolicalgame.co.uk/2011/07/exporting-animated-models-from-blender.html
