Writing Exporter Plug-ins

Global utility plug-ins inherit from the SceneExport class. An exporter plug-in must implement the following virtual functions:

• SceneExport::ExtCount() - The number of supported file extensions
• SceneExport::Ext() - The nth file extension without leading ".". E.g. "txt" instead of ".txt"
• SceneExport::LongDesc() - A detailed file output description.
• SceneExport::ShortDesc() - A short description of the exported file type, which appears in file save dialog.
• SceneExport::AuthorName() - A long description of the exported file type.
• SceneExport::CopyrightMessage() - A copyright message.
• SceneExport::OtherMessage1() - A message string.
• SceneExport::OtherMessage2() - Another message string.
• SceneExport::Version() - The version number of the export plug-in. The format is the major number times 100 plus the minor version. E.g. version 1.03 would be represented as 103.
• SceneExport::ShowAbout() - Called in response to display an about box.
• SceneExport::DoExport() - Perform the file export.

When performing a file export in the function SceneExport::DoExport(), you can use the 3DXI functions and classes instead of (or inconjunction with) IScene, Interface and INode.
