static_triangle

This simple example initializes Direct3D9 and draws a static pink triangle in the center of a black background. It shows how to create and use vertex buffers and shaders. For compiling shaders for Direct3D it uses the dxc library, which utilizes the DirectX effects compiler DLL that comes with Windows. This lets you compile shaders on the fly. You might also use the command line dxc tool to create your shaders up front if you have so many of them that compiling on the fly makes your program too slow.

For window creation this sample uses the Windows API. Direct3D needs a handle to the window it runs in so you need a method for setting this up. Other libraries that you can use include SDL2, Allen Dang's gform library and the walk library.

If you simply build this sample with go build the resulting program will keep a console window open while running. Use the build.bat to build instead, it passes the flag -H=windowsgui to the linker which gets rid of the console window.
