DirectX 9.0 beta 3

[ecperez]

This is the Beta 3 Release of Microsoft's DirectX 9.0 Software Development Kit (SDK). It contains all DirectX software required to create DirectX 9.0 compliant applications.

Major components include: DirectX 9.0 system components (runtimes); DirectX 9.0 Application Programming Interface (API) Documentation for each of the DirectX core areas (written for C++, C#, or Visual Basic developers); DirectX 9.0 headers & libraries; Sample applications and source code; miscellaneous tools and utilities.

The SDK has added a new member to its core technology called Managed DirectX, a DirectPlay port for the PocketPC, a High Level Shader Language for D3DX, and Windows XP parity on downlevel operating systems for DirectShow and the DirectX audio APIs.


DirectShow also has a new Video Mixing Renderer (VMR9) which uses D3D9 surfaces and always renders video through the 3D pipeline, along with new and exciting samples.

The generic Windows Media Format SDK stub library (wmstub.lib) available in previous beta releases has been removed. DirectShow samples using this stub library have been reverted to the DirectX 8.1 behavior of displaying a warning to obtain the stub separately, and the readme.txt files have also been reverted with information on the process to obtain the stub.

DirectX 9.0 Sample Browser: In the release of DirectX 9.0 Beta 2 SDK you saw our first release of the SDK Sample Browser. With the Beta 3 release we have added previously missing samples and fixed broken links. We know we have a few things left to fix, however we were confident enough with this version and your feedback that we removed the lengthy Start Menu hierarchy to execute samples and have left only the Sample Browser. Please give us your feedback on the browser itself, its usefulness, bugs found (not listed as issues below), and the removal of the Start Menu hierarchy.

Important notes:

Requires Microsoft® Windows® 98, Windows Me, Windows 2000 or Windows XP
Does not support either Windows 95 or Windows NT 4.0
Do not install the DirectX 9.0 beta on a machine that you need run the shader debugger for DirectX 8.1 code. There is a known issue in Beta 3 that prevents correct operation on DirectX 8.1 shaders. This will be fixed in the near future.
