Question

该模型是.fbx 我也尝试了很多模型，似乎没有什么工作我想知道是否有人可以帮助我，以下代码是我所有感谢！

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);
        }
    }
}

我没有看到您的代码出现任何问题，因此问题可能出在模型上。

可能是由相关模型文件引起的。 Blender上的股票FBX Exporter存在一个已知问题（我不知道您使用哪种建模软件制作模型，但事情仍然相关），这使得模型的导出尺寸比其大100倍搅拌机。结果是模型非常大，它不仅将摄像机封装在自身内部，而且还非常大，以至于它的多边形超出了观看的截头体。结果：模型确实已渲染，但除非您移动相机直到意识到缩放问题，否则它将永远不会出现在屏幕上。

我这样说是因为我自己处理了这个问题。如果您确实使用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
