Graphics in C++ [closed]

According to the C++/DirectX bundle, a high - quality source of information is MSDN.

• Creating a game app
• DirectX SDK Samples

DirectX Tutorial is a good resource.

Besides:

• There are code examples on CodeProject.
• On GameDev there are examples on OpenGL.
• A lot of useful information on gamedev.ru.

Qt to help you

Http://www.opengl.org/ The official website, there just needs to be a LOT of information, of course in English). It seems that there were lessons at NeHe, but I did not succeed with them. Russian-language resources are game dev.

There is also a certain unity. There are opengl for c#, and much more. Suddenly useful:)

To begin with, we recommend using opengl, as it is simpler and more compact.

Here is a full working example of the simplest application. The SDL library is used. For opengl, this is the same as STL for C++. Provides a convenient event handler, working with sound, devices.

Reference to SDL.
