VC.NET Game Development Chapter II Create 3D Scene

The code is still a bit problem, wait for me to debug, I will write more detailed points, but the comment is very detailed, I don't think it will be explained. I don't know that the memory overflows me again. Yesterday's problems have been solved // **************************************** **************************************************** / / Description: / / Development environment: .NET 7.1.3091 // Operating system: WindowsXP SP2 // s D K: Microsoft DirectX 9.0 SDK // Computer: // CPU :: Inter 2.6C // Memory: 1G DDR400 // Graphics: FX5900 128MB // Hard disk: 120g * 2 8MB 7200 // motherboard: inter865pe // ******************************************** ****************************** # Pragma Comment (lib, "D3D9 .lib ") # Pragma Comment (lib," d3dx9.lib ") # Pragma Comment (lib," dinput8.lib ") # Pragma Comment (Lib," DxGuid.lib ")
