Purpose

The module SoView2DSlicer allows for an interactive slicing (or stacking) through a volume image in a 2D viewer.

Interaction

Note that if you use Manged Interaction (see Managed Interaction) and want to map stacking to keys with a SoInteractionMapping module, the stacking through z-slices is done by changing the y-value, while stacking through time points is done by changing the x-value.

By default, the SoInteractionMapping maps keys to changes of the x-value.

If you want to use keys for stacking through z-slices, you have to use ;swap at the end of your mapping, e.g.:

slicer.SoView2DSliceOffsetAction:key:E/F;swap

This line in SoInteractionMapping will map the E and F keys to stacking through z-slices. If you omit the ;swap directive, those keys will stack through time points instead.

Visible Fields

Editing On

name: editingOn, type: Bool, default: TRUE

If checked, an interaction according to the tristate causes a slicing through the image.

see also SoView2DExtension.editingOn

Alt

name: alt, type: Enum, default: IGNORED

see SoView2DExtension.alt

Sensitivity

name: sensitivity, type: Float, default: 0.25, minimum: -2, maximum: 2

Sets the speed of slicing relative to the mouse movement.

A low sensitivity value causes a slow slicing. Negative values invert the slicing direction.

Step Size

name: stepSize, type: Integer, default: 1, minimum: 1

Determines the number of slices that the current slice is incremented / decremented on each step.
