DirectX 9.0 Features Revolutionary High-Level Shader Language

REDMOND, Wash. Jan. 22, 2003 Microsoft Corp. today announced broadened availability of the Microsoft® DirectX® 9.0 application programming interface (API). The latest version of the Microsoft Windows® Gaming API delivers Microsofts powerful new High-Level Shader Language (HLSL) and features its most-advanced suite of design tools for the development of rich multimedia elements such as full-spectrum color graphics, video, 3-D animation and enhanced audio capabilities.

Developed by Microsoft, creators of Direct3D® , HLSL is a revolutionary industry innovation for multimedia developers and the key component of this latest DirectX 9.0 release. Based on the C programming language, HLSL introduces a developer-friendly programming environment that delivers simplicity and flexibility across the full range of 3-D graphics. HLSL facilitates every aspect of development, from the creation of vivid art and animation to effects programming. Compatible with all DirectX-compliant graphics processing units, HLSL allows developers to define a similar visual effect across the widest range of graphics hardware. HLSL can be seamlessly integrated into the Visual Studio® IDE and complemented by enhancements to Microsofts current developer toolset to provide developers with even more power from an easier-to-use solution.

“Our principal goal with DirectX 9.0 is to make game development on the Windows platform more enjoyable, advanced and efficient. By allowing developers to create cutting-edge software without worrying about the hardware theyre creating it for, DirectX 9.0 lets developers concentrate on what they do best,”
said Dean Lester, general manager of the Graphics and Gaming Technologies Division at Microsoft.
“DirectX 9.0 continues to build on the advancements made in DirectX 8.1. The revolutionary new high-level shader language optimizes the hardware available today and will support all future hardware innovations as the technology moves forward, regardless of manufacturer.”

DirectX 9.0 introduces significant improvements across its suite of APIs. DirectSound offers new audio capabilities, DirectShow accelerates video rending hardware, and Direct3D enhances low-level graphics programmability with new programmable vertex and pixel shader 2.0 models.


The DirectX 9.0 Software Development Kit including HLSL can be downloaded from the DirectX Developer Center at . The latest version of DirectX is also available for free download (connect-time charges may apply) from the DirectX Home User Web page at .
