DDraw

DirectDraw is the part of DirectX which handles displaying graphics on the screen.

In the Wine context, when one speaks about DDraw, one speaks about all the 2D APIs (DirectX 1 to DirectX 7) but also all the 'old' 3D APIs (Direct3D1 to Direct3D7). This is to prevent confusion with Direct3D8 and Direct3D9 which, while keeping the same name, are a completely different set of APIs.

DDraw Versions and Interfaces

The DDraw interface numbers don't totally match up to the version of DirectX they were introduced:

  • DX 1 brings IDirectDraw and IDirectDrawSurface
  • DX 2 IDirectDraw2 and IDirectDrawSurface2
  • DX 3 adds IDirectDrawSurface3, IDirect3D, and IDirect3DDevice (IDirectDraw3 is an IE specific interface that lives in ddrawex.dll)
  • DX 4 adds IDirect3D2 and IDirect3DDevice2
  • DX 6 adds IDirectDraw4, IDirectDrawSurface4, IDirect3D3 and IDirect3DDevice3
  • DX 7 adds IDirectDraw7, IDirectDrawSurface7, IDirect3D7 and IDirect3DDevice7
