如何在 XNA+C# 中将纹理合并为一个？
我有一个模型，它不止只有一个纹理，我希望将这些纹理合并为一个纹理，这样我就可以为每个模型/网格使用一个纹理。
有没有一个好的算法呢？首选 C#，首选 XNA4。
提前致谢： 彼得
I have a model, that has more then just one texture, and I want to have these textures merged into one texture, so I can use one texture per one model/mesh.
Is there a good algorithm for this? Prefered C#, prefered XNA4.
Thanks in advance:
Péter

我认为最好的方法是在模型编辑器中执行此操作。
I think the best way would be to do this in your model editor.
虽然实现起来并不容易，但您可以制作一个模型处理器，将纹理合并为一个。
您可以使用此代码来了解如何操作：
A. 打包纹理：

B. 要更改模型以使用新纹理：

Though is not easy to implement you can do a model processor that merge the textures into one.
you can use this code to know how do it:
A. To pack the textures:

B. To change your model to use the new texture:

如果您确实愿意，可以在像素着色器中相当轻松地完成此操作。您基本上需要编写一个着色器，它接受两个纹理并将它们组合起来，然后将所述着色器绘制到纹理渲染目标。如果您不确定如何执行此操作，我建议您开始阅读着色器编程，因为它是 3D 图形编程不可或缺的一部分。
或者，您可以只使用多重纹理并避免合并纹理： http:// www.riemers.net/eng/Tutorials/XNA/Csharp/Series4/Multitexturing.php
You can do this in a pixel shader rather easily if you really wanted to. You would basically need to write a shader which takes in two textures and combines them then draw said shader out to a texture render target. If you're unsure how to do this I suggest you start reading up on shader programming as it's an integral part of 3D graphics programming.
Alternatively you can just use multitexturing and avoid merging texturse: http://www.riemers.net/eng/Tutorials/XNA/Csharp/Series4/Multitexturing.php
