NodeData Overview

Many plugin classes of the classic API are based on NodeData. Instances of such plugin classes can be added to and stored with a BaseDocument (like objects, tags, materials, etc.). To create such plugins it is needed to implement virtual functions of the NodeData class:

General functions are:

• NodeData::Init() / Alloc and Free Manual
• NodeData::Message() Manual

GUI related functions are:

• NodeData::GetDEnabling() Manual
• NodeData::GetDDescription() Manual

Parameter related functions are:

• NodeData::SetDParameter() Manual
• NodeData::GetDParameter() Manual

Internal data is handled with:

• NodeData::Read() / NodeData::Write() Manual
• NodeData::CopyTo() Manual

Several NodeData based classes but also some other plugin classes allow to draw in the editor viewport. See Draw Manual.

NodeData based plugin classes

The most used NodeData based plugin classes are:

• ObjectData
• TagData
• MaterialData
• ShaderData
• SceneHookData
• VideoPostData

Further NodeData based plugin classes are:

• EffectorData
• CTrackData
• GvOperatorData
• PrefsDialogObject
• SceneLoaderData
• SceneSaverData

It is also possible to create a new class directly based on NodeData and register the class with RegisterNodePlugin().
