Mac OS X Tiger to add OpenGL enhancements, PDF Kit, SQLite
Some of the less publicized features of Mac OS X 10.4 "Tiger" are beginning to emerge as developer sources compile notes from Apple's recent World Wide Developer Conference and preliminary tests of the next-generation operating system.
Although the majority of the features are based on additions to less apparent and underlying technologies, the advances will aid developers in producing more feature rich and streamlined applications in shorter periods of time, sources said.
OpenGL and OpenAL
The version of OpenGL that will ship with Tiger will include better support for pixel buffers, which lets developers perform offscreen rendering with OpenGL. For example, developers could create a pixel buffer to store a texture that may be applied to hundreds of different objects in a video game, though the texture would only be processed once.
Tiger will also add support for Open Audio Library (OpenAL), a cross-platform standard for delivering 3D audio in applications, sources said.
Using OpenAL, developers can implement high-performance positional audio in games and other programs that require high-quality audio output. And because OpenAL is a cross-platform standard, applications written using OpenAL on Mac OS X can easily be ported to run on many other platforms.
Tiger's implementation of OpenAL is reportedly based on the company's Core Audio library and therefore will deliver high quality sound and performance on Mac OS X systems.
PDFKit
PDF Kit is a new Cocoa framework in Tiger that will let developers add PDF viewing and navigation to their Mac OS X application with just a few clicks in Interface Builder. The kit will automatically handle the rendering of the PDF content and provide controls for navigation and setting the zoom level.
Developers may also choose to go beyond simple PDF viewing, as the PDF Kit PDF Kit includes a suite of developer classes for adding capabilities to perform text searches, manage selections, add annotations, and specify the behavior of some graphical elements.
Sources say that starting with the release of Tiger, Apple?s "Preview" application will use the new PDF Kit as the foundation for its PDF support.
SQLite Support
Another feature of Tiger is SQLite support, which incorporates the SQLite library into the system to provide an embeddable, zero-configuration SQL database engine for applications.
Developers who link their applications to this library can access SQL databases without running a separate relational database management system (RDBMS) process. The library can also be used to create local database files and manage the tables and records in that file.
Core Data Framework
SQLite is optimized to provide fast access to database records and is designed for general-purpose use. One example is Core Data--a new Apple framework that simplifies application creation based on a Model-View-Controller architecture--that uses SQLite extensively to provide backend storage for user-defined data.
Core Data is intended for applications that have a significant amount of structured data to manage. According to sources, the library will handle developer tasks such as retrieving object data from disks, maintaining references to those objects, and writing modified objects back to disk.
The new Tiger-only Core Data framework will also provide developers with simplified management of undo and redo operations, support for validation of property values, support for propagating changes, grouping, filtering, and organizing data in memory and transferring those changes to the user interface through Cocoa bindings.

Comments
This is almost overwhelming. I think it's safe to say Tiger will have a solid OpenGL implementation. OpenAL will be great if developers stop using DirectX for sound. If developers can start using OpenGL and OpenAL for their games, they would be able to easily port to Mac and Linux. I don't know why they create their games using DirectX and then decide to allow a port house to port the game...the cost would be substantially smaller if they built the game with OpenGL and OpenAL frameworks from the start.
PDFKit allowing PDF annotations is excellent news. Allowing developers to add a PDF viewer to their app with zero code is unbelievable.
And finally...a database solution for developers.
Tiger is going to spawn some commercial quality apps...but it won't take big companies to create them. The small developers will be able to produce these apps and most of it will probably shareware or even freeware since it'll be so easy to build.
Also of note if we're talking about pdfkit is ImageIO which should standardize the input/output of graphic file formats like TIFF, jpg, jpg 2000 and High Dynamic Range formats like OpenEXR and Floating Point Tiff(These do 16bit per channel or more for yummy graphics)
Core Data sounds like the "bee's knees" for any data that you need to be persistent. I look for Apple to show how nifty taking iLife apps and SQL'izing their backends can make for application integration and functionality.
We haven't even gotten into Quartz 2D Extreme either. I'm expecting some good ole fashion silky window redraws once that comes. I also read that some icons and widgets are moving from gif/jpg to png. Hmmm would that be because png can scale better once we get our resolution independance turned on?
I think Tigers is going to turn a lot of people on. While it doesn't look like a powerhouse to the layman now, wait until they see what applications can do under Tiger...they will roar man.
I mean look at what we're getting.
1. A nice lightweight SQL embedded into the OS.
2. Nifty networking features(mmm new Net Kernel Extensions perhaps).
3. New toys to make your GPU purrrrrrr(Core Image/Video)
4. The next wave of pdf improvements. Preview is nice now so any improvements are going to be cream. Appleworks 7 where are you?????
5. Scripting on steroids with Automator. Please people get rid of those photo files that start with "IMG" puhleeeze.
6. Threading and SMP improvements- Thread you Developers THREAD!!!!
7. Spotlight- No ma'am it isn't search...it's much much more.
8. Dashboards- I'm actually liking the potential of widgets here. Tiger is months away and there are already more than you can shake a stick at.
9. Xgrid built in. May come in handy when I get my Powerbook
10. .Mac Sync- Am I the only one that loves the idea of keeping my Addressbook, Mail Rules and whatever else I want sync'd between two computers? This could be heaven.
Shite. I can't wait..where's my iMac?
grounds: Impersonation
I think you put these technologies into terms we all understand better for instance WWDC Sessions

Nothing was spoken about directly on SQLite or OpenAL that's great info. I'm still hoping Apple buys a gaming company and let's them go wild creating great Mac games. That networking info in the other thread sounds nice too about the Core Foundation networking ehancements. Whoever is giving you the info tell'em we're thankful. More Quartz 2D info please and perhaps more info on cocoa framework changes if possible.
"Tanks"
1. SQLite and Core Data sure sound like a foundation for a MS Access killer...also possibly the foundation of a revamped AppleWorks 7 DB? It is minimally an "end run" in the sense that perhaps you don't need to take MS Access head on...but instead enable developers to simply build applications with DB backends in a "super easy" way. Also, I can imagine iPhoto, iTunes and AddressBook being "re-hosted" on this framework. After all, iPhoto is nothing more that a front end to QT plus a DB, and iTunes a front end for QT (audio) plus a DB. This is one more piece of a much larger puzzle that Apple seems to be putting together methinks.
2. PDFKit + existing AppKit text functionality sounds like a solid foundation for office-like content creation tools...word processor anyone? DTP application anyone?
That was not I who posted before, but no, the information in this report should not have been public. I doubt it is.

I *love* being able to save to PDF, but the files created are generally *huge* and you have to use 3rd-party shareware such as PDFCompress to strip 'em down to size...which doesn't always work very well.
"Supports databases up to 2 terabytes (2^41 bytes) in size.
Small memory footprint: less than 30K lines of C code, less than 250KB code space (gcc on i486)"
Now that's a superlite SQL server. Eat your heart out Longhorn...

I heard SQLite was very limited in function compared to most other SQL databases. It's wicked fast and has a tiny footprint but the tradeoff is that you can't do everything other database systems can do...is this right?
However, consider the engine that became WebCore. It's much better to start from a simple, clean base (30k lines of code!) and extend it than it is to license some giant beast and try to tailor it to your needs. The fact that SQLite has minimal support now doesn't prevent Apple from adding features to Core Data, even if Core Data is built over SQLite. For instance, the article mentions access to remote DBs, which SQLite can't currently do AFAIK. All it knows about is itself.
Or is this something else I am thinking about?

Absolutely. Tiger will really shine when after developers take advantage of the new technologies.
