在 DirectX 9 中加载 .X 模型 [英] Loading a .X model in DirectX 9

问题描述

我正在尝试为我的投资组合制作我的第一个 3D 演示，但我在加载多个 .X 文件时遇到问题，因此我可能能够制作一个简单的游戏.

I'm trying to make my first 3D demo for my portfolio but I'm having problems loading in multiple .X files so that I might be able to make a simple game.

我已经阅读了 msdn 教程和 Frank Luna 的书，这些书展示了如何在一个网格中加载.我什至尝试修改 franks 演示代码，但我发现他的代码只能做他打算做的事情.修改它只是一个完全令人头疼的问题.

I've worked through the msdn tutorials and Frank Luna's book that show how to load in one mesh. I even tried to mod franks demo code but I've found his code only does what he intended to. Modding it is just a complete headache.

我想知道是否有人知道并提供很好的帮助库或带有示例代码的网站，这可以消除将 .X 模型加载到游戏中的麻烦，并允许我移动它们等

I'm wondering if anyone knows and good help libs or websites with example code, that can take the hassle out of loading .X models into a game and allow me to move them etc

推荐答案

当我学习 DirectX 9 时，这个 网站是寻找信息的好地方.

When I was learning DirectX 9, this site was a good place to look for information.

简而言之，您必须调用 D3DXLoadMeshFromX 或其派生函数之一从文件(或内存)加载网格对象.

In a nutshell, you have to call D3DXLoadMeshFromX or one of its derivative functions to load the mesh object from a file (or memory).

您不能移动"对象本身，您必须推动/弹出矩阵以累积每个对象的平移/旋转.例如轮换:

You cannot "move" the object per se, you have to push/pop matrices to accumulate a translation/rotation for each object. e.g for a rotation:

float fAngle = 2.f;
D3DXMATRIXA16 matWorld;
D3DXMatrixIdentity(&matWorld); // Identity Matrix
D3DXMatrixRotationY( &matWorld, fAngle );
g_pd3dDevice->SetTransform( D3DTS_WORLD, &matWorld );
