[英]C# XNA 3D Model not rendering
該模型是.fbx,我也嘗試了許多模型,似乎什么也沒有用,我想知道是否有人可以幫助我,以下代碼是我所要感謝的!
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);
}
}
}
我沒有發現您的代碼有任何真正的問題,因此問題可能出在模型上。
這可能是由於所討論的模型文件引起的。 Blender上的原始FBX導出器存在一個已知問題(我不知道您使用的建模軟件是用來制作模型的,但問題仍然存在),導致導出的模型尺寸比實際尺寸大100倍。攪拌機。 結果是該模型太大,以至於它不僅將相機包圍在內部,而且太大,以至於多邊形超出了視錐范圍。 結果:該模型確實已渲染,但是除非您移動攝像機直到意識到縮放問題,否則它永遠不會出現在屏幕上。
我說這是因為我自己處理了這個問題。 如果您確實在使用Blender,則應使用在此頁面中找到的導出器: http : //blog.diabolicalgame.co.uk/2011/07/exporting-animated-models-from-blender.html
