Please release me . . .
With the Computer Games Developers Conference serving as the perfect backdrop, we were pleased to officially announce the release of the DirectX 6.0 beta version on May 5, 1998. This new version of our groundbreaking set of multimedia APIs will speed development with greater stability, reliability, and consistency. It includes significant enhancements to Direct3D and DirectDraw, and introduces DirectMusic, a new API that delivers high-quality music to the Windows platform. For details on these and other updates and upgrades to DirectX, take a look at the press release Non-DirectX Site we've prepared.

Sound advice
Are the simple beeps and buzzes of yesterday's computer games good enough for your cutting-edge projects? Or are you looking to add audio that has a little more edge to it? What if you could move sound through virtual 3-D space with features like Doppler effects and sound cones? If that's more what you have in mind, you'll want to jump over to the June issue of Microsoft Systems Journal Non-Microsoft Link for Jason Clark's excellent article on using DirectSound to add dimensional sound effects to your Windows-based applications.

Bits and pieces: DirectX 5.2 for end users
A while back we released version 5.2 of the Microsoft® DirectX® software development kit (SDK). DirectX 5.2 SDK shipped with some important changes, including an upgraded edition of Microsoft Internet Explorer, the DirectX Media team's latest version of DirectPlay, and more. Now we're pleased to announce the availability of DirectX 5.2 for end users. These end-user bits will ensure that you can take full advantage of the latest multimedia features and innovations made possible by DirectX. To get your copy, head on over to the DirectX User Downloads department.

Direct translation
Our crack team of expert linguists has rendered the DirectX software development kit (SDK) Help files into impeccable Japanese. Up until now, you had to access the Japanese-language version of our site to download a copy. Now, you can get your copy by just heading on over to the Developer Downloads department.

Playing the DirectSound3D API
There's more to creating a great game than just super visuals. You have to know how to make a sound environment that really, well, hums. In "Avoiding a DirectSound3D Disaster," Non-Microsoft Link Game Developer writer Rich Warwick tells you what you've got to know to write to the DirectSound3D API. Learn when to go easy with 2-D sound, and when to rock them with 3-D sound in this informative article that tells you the difference between 3-D positional audio, virtualization, and spatialization, and when and how to use them to your advantage.

Two monitors are better than one
One of the great new features supported by DirectX 5.0 is multi-monitor display. Built into Windows 98 and Windows NT 5.0, the "Multimon" feature gives developers incredible opportunities to expand screen real estate in games, presentations, and applications. At Meltdown 97, Microsoft developer Todd Laney delivered a slide presentation that offered a quick overview of Multimon, with tips, traps, and a look at Multimon in DirectX. We've archived Todd's Multimon slide show Non-DirectX Site on the Microsoft Hardware Development site. Be sure to take a look.

Department of related information
We've labored long and hard to create a logical organization for the content we've collected on this Web site, but not everything fits into nice neat categories. Our solution? An odds and ends page. There you'll find things like end user licensing agreements, slide presentations, SDK information, and much, much more. Called the Related Developer Information page, it's sort of like that junk drawer in the kitchen filled with useful stuff that you know will come in handy someday.

It shall be released!
One of the big questions at the recent Meltdown conference was: When will DirectX 6.0 be released? Having presented our crack crew of engineers and programmers with just the right combination of threats and incentives, we can assure you that DirectX 6.0 will be released in July 1998. The new release will offer significant enhancements to Direct3D, running the gamut from A (as in Alpha in Texture Palettes) to Z (for Z-Buffer Clearing). We're also planning on mid-May for a general beta release of DirectX 6.0. Jump over to our press release page for more details.

License to thrill
Okay, so you've created this great new application and you want to distribute DirectX along with it. How much will it cost? What permissions are required? The short answers are "nothing" and "none." If you'd like a few more details, please take a look at our DirectX Licensing FAQ, which answers questions about using and distributing DirectX. And if you'd like to read all the fine print, check out our End User Licensing Agreements (EULAs). In addition to a EULA for the DirectX SDK, we have two new documents: a EULA for the Supplemental Driver Library (DDK), and a EULA for end user usage.

Lighting, the transformation pipeline, and D3D
Two big questions for DirectX developers: 1) How can I apply light sources to my 3D objects?; and 2) how can I best render my 3D models in screen space? Microsoft software engineer Iouri Tarassov has written a couple of white papers that have the answers. The first, "Lighting in Direct3D," explains how to use Direct3D lighting parameters and compute vertex colors. The second, "The Direct3D Transformation Pipeline," offers technical information on the three Direct3D transformations that convert 3D models to pixel coordinates.

The Inside scoop
Bradley Bargen and Peter Donnelly, both members of the Microsoft DirectX team, recently joined forces to create the definitive guide to DirectX. The result is Inside DirectX, an impressive new work that includes 576 pages and a CD-ROM's worth of authoritative information on how DirectX works and the best techniques for incorporating the power of DirectX into your development projects. You'll find it to be an invaluable desktop reference guide and an essential hands-on guided tour. Visit the Inside DirectX page Non-DirectX Site at the Microsoft Press Web site for more information on this great resource.

WinHEC of a great new product
Excite's Computers & Internet section reviews some of the features of DirectX 6.0 demonstrated at the Windows Hardware Engineering Conference (WinHEC) in Orlando, Florida. The news is positive according to writer Robert Lemos, who says that Microsoft is "preparing to add a whole new level of interactivity to computer games." See what's new in DirectX 6.0 in Lemos's article, "Playtime: Microsoft's new DirectX aids gamers."
