, use the CPU to draw all your genie, polygon and particles-and people are still doing this. Like unreal, Age of Empires II: Age of Kings has an excellent software Renderer-otherwise you will use one of two possible graphics APIs, OpenGL or DirectX. OpenGL is a real cross-platform API (software written using this API can run on Linux, windows, and MACOs .), It has many years of history and is well-known, but it has begun to show its ancient history. About four years ago, defining an OpenGL-drive

The result is that you can select a video source and click OK to return to the system in seconds. You can check the development documentation and find that the cvcreatecameracapture (INT index) function can select a cam
