GxApi is a cross-platform graphics API that is part of the World of Warcraft engine. It:
- Creates/destroys the window in which the game runs, which starts the game being able to read input events
- Loads/unloads texture and geometry data
- Creates/destroys textures
- Draws to the window
Graphics device
GxApi supports multiple low-level graphics APIs such as OpenGL and Direct3D (DirectX) 9. It does this by wrapping an base interface class, CGxDevice, whose
virtual member functions handle the actual calls to the graphics driver.
Windows device
On Windows, the derived classes include:
CGxDeviceOpenGl- OpenGL implementation. Enabled by passing
-openglas a command-line argument, or by setting a CVar prior to launch:SET gxApi "OpenGL" CGxDeviceD3d- Direct3D 9 (DirectX) implementation. Enabled by passing
-d3das a command-line argument, or by setting a CVar prior to launch:SET gxApi "D3D9" CGxDeviceD3d9Ex- Direct3D 9Ex (DirectX) implementation. Enabled by passing
-d3d9exas a command-line argument, or by setting a CVar prior to launch:SET gxApi "D3D9Ex"
