DX 3
Advertisement
G''day!
NT only has DX3 and that''s all it will ever have, that''s one reason to consider it.
If you build a program using the DX7 interfaces it will require DX7 to be installed. You can limit yourself to the DX3 interfaces and then it will work on DX3 or newer.
Unless you have a very good reason to want to support DX3 (and you may), don''t do it. It''s very old, and not very good. If all you need is simple 2D graphics and simple sound (no 3D anything) it might be okay.
Stay Casual,

DX3 will support 16bit colour.
I don''t think you''ll have much look with 3D sound though. Maybe with simple buffer playback. If you want to do any D3D stuff in DX3, then it was before the introduction of DrawPrimitive so you''ll have to use execute buffers (sort of like low level command lists - if you''ve done any PSX or PS2 programming you''ll get the idea).
As for compatibility:
1) An app built with the DirectX 3 SDK, and using DirectX 3 or lower interfaces/objects *will* work with DirectX 7 (and 5, 5.2 6, 8, 8.1 etc)
2) An app built with the DirectX 7 SDK and using DirectX 3 or lower interfaces/objects *will* also work with DirectX 3, 7, etc.
3) An app built with the DirectX 7 SDK and using DirectX 7 (or 5 or 6) interfaces/objects *will NOT* work on DirectX 3 (or 5 or 6).
