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() .
