fast::SlicerWindow class
#include <FAST/Visualization/SlicerWindow.hpp>

Window for showing slices of 3D data.

Contents

This window shows 3 views with slices of the volume data in three different directions (X, Y, Z). This windows features a slider for each view which controls which slice of the volume is being displayed. It also has a widget for controlling intensity window and level which is often needed for CT and MRI data. Use the SlicerWindow::connectImage and SlicerWindow::connectSegmentation methods to connect data to this window. The window will setup the appropriate renderers for you.
