DirectX 9

DirectX 9 was introduced in December 2002. The most important change was the implementation of High Level Shading Language (HLSL) which made it easier for developers to create 3D graphics and effects. Another new feature is an API which offers Patch-Meshes, common Polygon-Meshes together with improved realtime-animation capabilities.

Versions
Microsoft implemented updates into the DirectX 9.0c branch between 2005 and 2010, instead of releasing a new version like 9.0d. This makes it kind of hard to distinguish between 9.0c releases which work on Windows 98 and those which doesn't, unless you check for the package release date which is used for this list.
