查看“DirectX 9”的源代码

DirectX 9 是 2002 年 12 月推出的 [[Microsoft DirectX|DirectX]] 版本。最重要的变化是高级着色语言（''High Level Shading Language''，HLSL）的实现，这使开发人员可以更轻松地创建 3D 图形和效果。以前，开发人员必须以汇编语言的形式编写着色器。另一个新功能是一个 API，它提供 ''Patch-Meshes''、常见的 ''Polygon-Mesh'' 以及改进的实时动画功能。

==Versions==
Microsoft implemented updates into the DirectX 9.0c branch between 2005 and 2010, instead of releasing a new version like ''9.0d''.<ref>http://falconfly.3dfx.pl/directx.htm</ref> This makes it harder to distinguish between 9.0c releases which work on Windows 98 and those which don't, unless you check for the ''package release date'' which is also used for this list.

Since DirectX 9.0c, offline installer packages usually follow the name pattern <code>directx_''date''_redist.exe</code>, where ''date'' is replaced by the month and year of the package's build date, for example <code>directx_''Jun2010''_redist.exe</code> or <code>directx_''Dec2006''_redist.exe</code>.
