If you have friends reading these series of blogs, congratulations! You will see the worst blog in history about DirectX. Haha, if you don't understand, you can communicate in a timely manner
There are too many materials about DirectX, just like the textbooks I mentioned in my previous blog, they are all the Bible of the gaming industry. I suggest taking a look, they are all entry-level. So I will explain it in a note taking style here
Initialize DirectX
Initializing DirectX is divided into four steps, and only the methods are listed here. The specific steps can be found in any game programming book Creating a DirectX interface Function DirectX3DCreate9 (.)
Obtain device hardware information
Function GetDeviceCaps
Three Fill D3DPRESENT_ Arameters structure This one is to define a D3DPRESENT_ Parameters structure, fill in the content inside
Creating Direct3D device interfaces Function CreatDevice
I won't go into much detail about this kind of initialization work, and I don't know how to handle children's shoes. You can ask me for a demo See, I'll say it's the worst technology BLOG in history, haha
Below are some initialization codes posted
