Project Description

Objective	Approach and Plan	Progress and Next Steps
Create reusable widget that provides Editor functionality to create segments in Segmentation nodes	Use existing segment selector widget instead of per-structure box to select segment in a segmentation Provide adaptor to use existing python Editor effects Drawn shapes are stored in binary labelmap representation ("C" in representations image above) in the selected segment. It can be then converted manually or automatically to other representations.	C++ Qt widget using SegmentTable created New mode for editor with single selection and only name and color shown Decision made to re-implement Editor effects Conceptual differences Master volume is not absolutely necessary for segmentations (only a volume geometry) Preferably create one effect object for each effect, not one for each slice view PaintOver function is a big conceptual difference that would necessitate using tricks Python adaptor is not less complex than re-implementation Possibility of a nicer user interface Redundant effects (MakeModelEffect) Redundant effect parameters (color for morphology) Progress made with implementing paint effect, but no working prototype yet
