#include <QmitkTransferFunctionWidget.h>
Widget for editing the three components of a volume rendering transfer function.
Provides interactive canvases for:
- Scalar opacity (grayvalue to opacity mapping)
- Color (grayvalue to RGB color mapping)
- Gradient opacity (gradient magnitude to opacity mapping)
Includes a range slider for zooming into a subrange of the scalar domain. Each canvas shows the underlying histogram and supports adding, removing, and dragging control points.
