使用OpenGL时，C ++在C＃中存在哪些优点 [英] What advantages exist in C++ over C# when working with OpenGL
问题描述
我开始在OpenGL中获得感兴趣的学习，我试图找出在学习过程中使用哪种语言的最佳方向。我已经非常熟悉C＃，从我已经阅读，我可以利用Tao API与C＃代码的OpenGL接口。但是，我从我正在读的东西似乎是真正专业的OpenGL开发人员是C ++程序员。
I am starting to get interested learning in OpenGL and I am trying to figure out what the best direction to go as far as which language to use in the learning process. I am already very familiar with C# and from what I have read, I can utilize the Tao API to interface with OpenGL from C# code. However, it also seems to me from what I'm reading that those who are really professional OpenGL developers are C++ programmers.
我很好奇C ++可能有什么优势C＃在OpenGL中使用3D图形。任何输入将是伟大的，因为我是一个完整的newby在所有这一切。
I'm curious what advantages C++ might have over C# when working with 3D graphics in OpenGL. Any input would be great as I'm a complete newby at all this.
推荐答案
使用OpenGL通过C＃有一些困难。 / p>
Using OpenGL via C# has some difficulties.

获取最新的SDK。 Tao自2008年以来没有更新。OpenTK自2010年6月以来没有稳定版本。从2010年6月以来，OpenGL已经有两个版本。这是很多功能，你根本无法从C＃ 。我不知道OpenTK的夜总会有多稳定，但我一般不相信夜总会。使用C / C ++，你可以得到任何你想加载的函数指针。使用C＃，你只能使用你的工具包提供的。
Getting an up-to-date SDK. Tao hasn't been updated since 2008. OpenTK hasn't had a stable release since June of 2010. OpenGL has had two version releases since June 2010. That's a lot of functionality you simply cannot access from C#. I don't know how stable OpenTK's nightlies are, but I generally don't trust nightlies. With C/C++, you can get whatever function pointers you want to load. With C#, you can only use what your toolkit provides.
在C＃中处理缓冲区对象可能会很痛苦。是的，有办法将统一值的数组上传到缓冲区对象。但是构建交织的顶点数据，其中不同的组件具有不同的类型，在C＃中要困难得多。在C和C ++中，您可以直接访问内存。所以很容易有一个3向量的浮点数，后面跟一个4个字节的向量，每个顶点存储16个字节。在C＃中更难。
Dealing with buffer objects can be quite painful in C#. Yes, there are ways to upload arrays of uniform values to buffer objects. But building interleaved vertex data, where different components have different types, is much more difficult in C#. In C and C++, you have direct access to memory. So it's easy to have a 3-vector of floats followed by a 4-vector of bytes, all stored in 16 bytes per vertex. It's rather more difficult in C#.
图形代码通常是性能更为关键的代码区域之一。如果你正在做一个高性能的渲染应用程序，如游戏，你通常会想要C ++提供的控制。
Graphics code is generally one of the more performance-critical areas of code. You will generally want the control that C++ affords if you're making a high-performance rendering application like a game. So many of C#'s nice features work against it here.
使用C＃提供的唯一真正的优势是。它是C＃。在你觉得优势你的程度，那么它是一个优势。
The only real advantage that using C# provides is that... it's C#. To the degree that you feel that advantages you, then it is an advantage.
