This is the second release of the Adobe After Effects 3.1 Software Development Kit. This SDK provides the information you need to develop Effects and I/O Plug-ins for Adobe After Effects 3.1 on the Macintosh. It provides a description of the programming API and sample source code and project files demonstrating the various plug-in types.
If you are upgrading from the prerelease 3.0 version of the SDK, you won't need to update your plug-ins as the After Effects API has remained unchanged, but you will find documentation improvements in both the SDK Guide and the header files. If you are upgrading from version 2.0 of the SDK, you will find substantial API changes which require modification to your code. The SDK Guide and header files document the After Effects 3.1 API changes.
To install the SDK, launch the self-expanding archive and follow the on-screen prompts. The installer will create an "After Effects 3.1 SDK" folder at the root level of your hard disk. Within this folder you will find subfolders containing the SDK documentation and example plug-in source code. Each of these contain another "Read Me" file describing their contents.
The After Effects SDK documentation is in pdf format which is readable using the Adobe Acrobat Reader. If you don't already have the Acrobat Reader, it can be downloaded free of charge from the Adobe Web site (www.adobe.com). The After Effects code samples were written using Metrowerks CodeWarrior 10.
For the latest information on joining the Adobe Developers Association, and hence obtaining technical support for this SDK, obtaining newer copies of this SDK, and obtaining SDKs for other Adobe products, please look at the Developer Relations area on the Adobe Web site (www.adobe.com).
