Constructor & Destructor Documentation

TFEditorPrimitive()

inviwo::TFEditorPrimitive::TFEditorPrimitive ( TFPrimitive & primitive )

explicit

Constructs a TransferFunction editor primitive. The graphics item is positioned at the primitive location (scalar value and opacity) within the scene. The graphical representation should thus be centered around (0,0) in local coordinates.

Parameters

primitive

the primitive

Member Function Documentation

onTFPrimitiveChange()

virtual void inviwo::TFEditorPrimitive::onTFPrimitiveChange ( const TFPrimitive & p )

overrideprotectedvirtual

Reimplemented from inviwo::TFPrimitiveObserver.
