MosaicData

MosaicData is the central application-state object for the GUI. It wraps a headless Session with two DataContainerInteractor instances, one for point clouds and one for fitted models, and coordinates between them.

Each instance carries the following attributes:

• data: DataContainerInteractor over the point-cloud container.

• models: DataContainerInteractor over the fitted-model container.

• active_picker: name of the container currently bound to the area picker ("data" or "models").

• shape: bounding-box shape of the point-cloud workspace.
