OpenGL的工作时，在C＃中的C ++有哪些优势 [英] What advantages exist in C++ over C# when working with OpenGL
问题描述
我开始让感兴趣的学习在OpenGL中，我试图找出什么是最好的方向去尽可能在学习过程中要使用的语言。我已经很熟悉了C＃，从我读过，我可以利用API涛从C＃代码使用OpenGL接口。然而，它也似乎我从什么我读，那些谁是真正的专业OpenGL的开发商是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，可能有什么优点C ++了与在OpenGL 3D图形工作时，C＃。因为我对这一切完全纽比任何投入将是巨大的。
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
通过C＃使用OpenGL的有一定难度。
Using OpenGL via C# has some difficulties.

获得一个向上的最新SDK。陶一直没有更新自2008年OpenTK一直没有自2010年以来的OpenGL月稳定版本已的两个的版本发行，因为2010年6月这是一个很大的功能，你根本无法从C＃访问。我不知道OpenTK的Nightlies版如何稳定是的，但我一般不信任Nightlies版。用C / C ++，你可以得到你想要加载任何函数指针。在C＃中，你只能用你的工具包提供了什么。
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.
与缓冲区对象处理可以在C＃中相当痛苦。是的，有办法上传均匀值数组缓冲对象。但是建立交错顶点数据，其中不同的组分具有不同的类型，是在C＃困难得多。在C和C ++，你要直接访问内存。所以很容易有花车后面的字节4向量的3矢量，全部保存在每个顶点16个字节。这是在C＃中比较困难。
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#.
图形代码通常是代码的更高性能的关键领域之一。通常你会想要一个C ++，如果你喜欢做一个游戏的高性能渲染应用程序得到控制。因此，许多的C＃的很好的功能对着干这里。
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.
唯一真正好处，使用C＃提供的是.. 。这是C＃。为了一个你认为你的优势，那么这是一个优势的程度。
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.
