Apple Game Sprockets for Cutting-Edge Multimedia and Internet Games
on the Macintosh
Apple Game Sprockets is a new software development kit (SDK) to create advanced
multimedia and Internet-enabled games for Mac OS-based computers. Using this SDK,
all Mac OS-compatible games can feature real-time 3D graphics, 3D sound, Internet
support, speech recognition, and input device/monitor control.
Available royalty-free to all developers, Game Sprockets profoundly simplifies
the creation of Apple Macintosh entertainment software. Game Sprockets includes the
final release of QuickDraw 3D RAVE (Rendering Acceleration Virtual Engine), a
multi-platform technology that enables game developers to incorporate plug-and-play
3D acceleration hardware.
Game Sprockets encapsulates many current Mac OS technologies into a uniform
interface. So a developer who wishes to add support for a feature can use a simplified
game-oriented interface instead of the more daunting original API.
The current Apple Game Sprockets SDK includes:
• NetSprocket - Internet and multi-player gaming API
• SoundSprocket - 3D sound and Sound Manager API
• SpeechSprocket - speech recognition API
• InputSprocket - digital joystick control and input device API
• DrawSprocket - multiple buffering/display control API
• QuickDraw 3D RAVE - fast, multi-platform 3D graphics API
Apple Game Sprockets Technical Details
NetSprocket
NetSprocket provides standard, customizable user interface dialogs for
configuration, log-in, and hosting a game across the network. A simple set of calls
allows messages to be singlecast, multicast or broadcast to other machines within the
game. A theoretical maximum of two billion users can simultaneously use NetSprocket
across a broadband connection.
NetSprocket also provides transparent access to Internet-oriented gameplay and
multi-player gaming. This API uses Open Transport for TCP/IP, AppleTalk (with
support for LocalTalk, EtherTalk or TokenTalk) and modem communication access. By
utilizing a client/server topology, it is possible for gamers to use multiple protocols
in a single session and with minimal overhead (a total of 28 bytes are used per player
for the message header). NetSprocket also supports the creation of groups for
broadcast of data to specific users across the network.
SoundSprocket
SoundSprocket incorporates a standardized API for accessing both traditional
sound functions as well as new 3D sound technologies developed by Apple. For 3D
sound, the listener and each sound channel are given specific positions and velocity
vectors in a virtual audio space. These positions are changed during game play, along
with the sounds themselves, to give the impression of spatiality and movement.
The signal processing, taking advantage of the capabilities of the PowerPC
microprocessor, simulates Doppler Effect, distance attenuation, environmental
reverberation and spatial positioning. The 3D effect may be effectively presented over
speakers or headphones; it is also fully integrated with the camera position used in
QuickDraw 3D, which enables sound to “follow” the player in 3D space.
InputSprocket
InputSprocket provides a compact API through which games can communicate
with drivers for analog or digital joysticks and other game-oriented input devices. It
also provides user interface elements that allow player override of the default control
options through specified dialog boxes. Mouse and keyboard support are also enabled,
as are multiple input device support.
DrawSprocket
DrawSprocket allows developers to easily utilize multiple (double or triple)
buffering on the Macintosh for smooth display of graphic images. Multiple buffering is
achieved by DrawSprocket using the best option available on the user’s system - true
double buffering in hardware, page-flipping, efficient memory copies, or through the
traditional CopyBits function call. The game does not need to be aware of the hardware
specifics.
DrawSprocket also enables configuration of display resolution or color depth
without leaving the game environment (no need to access the sound and displays control
panel) and screen sizing/blanking. A sprite engine, available through QuickTime, may
also be used in tandem with DrawSprocket.
SpeechSprocket
Based on Apple’s PlainTalk technology, this API allows developers to easily
include high-quality speech recognition in their game titles.
QuickDraw 3D RAVE
Recently announced as the first component of Apple Game Sprockets, RAVE
enables developers to transparently access 3D graphics accelerators for maximum
speed and throughput while also providing exceptional 3D rendering speed in software.
RAVE lets game developers leverage their existing rendering technologies - a key issue
for vendors seeking to differentiate their content. RAVE is shipping now for Power
Macintosh and Microsoft Windows 95, with a Windows NT version due in April 1996.

VRML Conclusion: Moving Worlds
The Moving Worlds proposal has been picked to be the next VRML standard, and the
binary file format will be based on the Apple 3DMF format. The first VRML was
largely an academic project promoted by individuals and visionaries. The competition
to develop VRML 2.0, in contrast, was dominated by computer industry giants like
Silicon Graphics, Netscape, Apple, and Microsoft.

Motorola Ports Their Optimizing Compilers
to All Platforms
Version 3.0 of the Motorola C/C++ Software Development Kit (SDK) for Mac OS offers
a complete set of development tools for Apple’s Macintosh Programmers’ Workshop
(MPW) environment, including the Kuck & Associates Preprocessor (KAP). This new
version of the Motorola SDK includes “plug-in” versions of the C/C++ compilers that
can be directly used by licensees of the Metrowerks CodeWarrior and Symantec
Project Manager development environments. The Motorola SDK also includes versions
of the highly optimized “libmoto” libraries that are compatible with the Apple,
Metrowerks and Symantec environments.
The Motorola SDK 3.0 will bring the highest performance available to Mac OS
developers, enhancing applications such as interactive entertainment and computer
games. Tests have shown that code generated by the Motorola compiler is up to 18% to
29% faster than code generated by other industry-standard compilers for a broad
series of industry-standard benchmarks, including Nullstone, Dhrystone, Whetstone,
Linpack and the BYTE benchmarks.
As the first SDK to provide support for Apple’s MPW, Metrowerks’ CodeWarrior
and Symantec’s Project Manager development environments, the C and C++ compilers
enable developers to optimize code simultaneously for members of the PowerPC family
of microprocessors, including PowerPC 601, PowerPC 603, PowerPC 604 and
PowerPC 620, while still maintaining code compatibility across all PowerPC family
members.
The Motorola C/C++ SDKs are available for an initial list price of US$299 by
calling (800) 347-8384 in the U.S. or (512) 891-2999 internationally. This
package includes MPW and a complete set of documentation.
A “plug-in” kit consisting of only the Motorola C/C++ compilers, assemblers
and “libmoto” libraries for the CodeWarrior and Symantec Project Manager
environments is also available for an initial list price of US$99. Both packages
include one year of maintenance and product upgrades.
