C ++ OpenGL应用程序作为Web服务 [英] C++ OpenGL application as a web service

问题描述

我们已经创建了C ++ OpenGL应用程序可视化哪一些物理模拟。基本应用程序包含其用于通过一个简单的GUI DLL中。它当前运行在台式机上，但我们的想法，把它变成一个Web服务。

We have created an OpenGL application in C++ which visualizes some physical simulations. The basic application is contained within a DLL which is used by a simple GUI. It currently runs on a desktop PC, but we have the idea to turn it into a web service.

由于模拟需要专用的硬件，这个想法是，一​​个用户通过他/她的浏览器可以与我们的作为服务的应用程序进行交互，然后该服务的结果呈现给一个图像（jpg或任何适当的），那么，可以显示/更新的浏览器。

Since the simulations require dedicated hardware, the idea is that a user, through his/her browser can interact with our application as a service and this service then renders the result to an image (jpg or anything appropriate) that can then be displayed/updated in the browser.

我的问题：
我怎么能轻而易举地描述成一些服务器上运行，这样我可以在网上接近它的Web服务变成一个C ++应用程序？我应该看什么样的技术/ API的？而是否有解决类似的问题，任何现实生活中的例子？

My question: How can I "easily" turn a c++ application as described into a web-service that runs on some server so that I can approach it over the web? What kind of technologies/APIs should I look at? And are there any real-life examples that tackle a similar problem?

推荐答案

这是可能的，但你有一个主要的困难是试图使用OpenGL从web服务。你需要这个端口做100％的离屏渲染和工作，而一个窗口背景。这将是我的第一步，而且它并不总是微不足道的。

This is possible, but one major difficulty you'll have is trying to use OpenGL from a web service. You'll need to port this to do 100% offscreen rendering and work without a windowing context. That would be my first step, and it's not always a trivial one.

此外，它是很难维持和web服务正确管理你的OpenGL上下文，以及所涉及的开销可能是相当痛苦的。根据效果图的数量和种类，您可能会遇到一些问题存在。

Also, it is very difficult to maintain and manage your opengl contexts from a webservice correctly, and the overhead involved can be quite painful. Depending on the number and types of renderings, you may run into some issues there.
