Programming in the 3DO Environment


This section provides background information about libraries, header files, and documentation that makes writing your first program easier.

Libraries

The development environment consists of a large number of libraries and header files. They include:

The 3DO Portfolio Operating System

This section briefly looks at how you can benefit from having an operating system, then discusses how to include the correct header files in your program.

Benefits of an Operating System

3DO Portfolio, the 3DO operating system, makes programming for the 3DO system easier, faster, and more robust.

Portfolio lets you interface to the 3DO hardware in a more abstract manner than is usually the case on competing products like Sega and Nintendo. This extra level of abstraction enables multiple hardware vendors to supply radically different implementations of the 3DO standard, yet continue to run all existing software titles.

For example, Portfolio is the reason why all 3DO titles can run on both the Panasonic REAL player, and the Creative Labs 3DOBlaster. Even though the two systems are quite different, Portfolio hides the differences.

In addition to automating compatibility with different hardware platforms, Portfolio offers many general-purpose operating system services which make programming easier and faster. For example, multitasking lets you program quicker and make better use of the system bandwidth.

Portfolio Folios and Libraries

Portfolio consists of several runtime libraries (folios) and other libraries. During title development, you should only include those libraries that your title actually needs. To find out what library a particular function comes from, see the “Associated Files” field in the function description for the function in question (see Documentation for more information).

Lib3DO and the 3DO DataStreamer

Some available libraries are not part of the 3DO Portfolio operating system:

Documentation

Documentation for the 3DO Toolkit and the 3DO Portfolio operating system is available both in hardcopy format and online.

Starting with the 3DO Portfolio 2.5 release, both 3DO Portfolio and 3DO Toolkit documentation is available in html format. You can look at the documentation, taking advantage of the extensive hypertext links provided, using any html viewer (like Mosaic or Netscape) on your Macintosh or UNIX workstation. (PC compatibility is not possible in this release because of filename limitations)
