Implement A New Node

Case Study: CameraNode

The camera node provides a great example of a node that "does a little bit of everything". Camera nodes encapsulate the following functionality:

• Implemented in its own module.
• Stored in the scene graph.
• Selectable on the worksheet.
• Transformable on the worksheet.
• Uses custom rendering.
• Uses a property sheet to provide editing access.
• Uses a data interface for scripted access.
• Uses a custom icon.

Module Implementation

The ExternalModule for CAMERA.DLL is implemented with two files, a C++ class and header. This class required for Scenome to load this module as a plugin.

• cameramodule.cpp
• cameramodule.h

Base Implementation

Camera is implemented with two files, a C++ class and header.

• camera.cpp
• camera.h

Property Sheet Implementation

The property sheet for a camera node is implemented with two files, a C++ class and header.

• camera_propertysheet.cpp
• camera_propertysheet.h

Select/Pick Implementation

Camera select/pick is implemented with two C++ classes.

• camerapickmodule.cpp
• cameraselectfiltermodule.cpp

Transform Implementation

Camera transformation is implemented with one C++ class.

• cameratransformexecutionmodule.cpp

Editing Action Implementation

Integration into the undo/redo system is handled with one C++ class and one header.

• editcameratransformaction.cpp
• editcameratransformaction.h
