2D View Controller

Each 2D slice view includes a compact controller for quick view actions and display options. Use it when you want to adjust the current slice view without opening a larger settings panel.

The controller covers view reset, zoom, screenshots, flip actions, ruler settings, orientation marker settings, view visibility options, and background options.

Main Buttons​

  • Center: Fits the current slice view to the available space.
  • Zoom In: Increases magnification for the current slice view.
  • Zoom Out: Decreases magnification for the current slice view.
  • Screenshot: Captures an image of the current slice view.
  • Flip: Opens flip options for the current slice view.
  • Ruler: Opens ruler display options.
  • Orientation Marker: Opens orientation marker style and size options.
  • Visibility: Opens visibility and interpolation options.
  • More Options: Opens detach, fullscreen, and background options.

Screenshot​

Click Screenshot to save an image of the current slice view. Volvicon asks for a name and stores the screenshot in your pictures folder.

Use this when you need a quick export of the current slice display for reports, review, or comparison.

Flip Options​

The Flip menu changes the orientation of the current slice view. These options affect only the current slice view.

  • Horizontal: Mirrors the current slice view left-to-right.
  • Vertical: Mirrors the current slice view top-to-bottom.
  • Both: Applies both horizontal and vertical flips.

Ruler Options​

The Ruler menu controls the ruler shown in the slice views. Ruler type and ruler color are synchronized across all three slice views.

Ruler Type​

  • Off: Hides the ruler.
  • Thin: Shows a thinner ruler style.
  • Thick: Shows a thicker ruler style.

Ruler Color​

  • White: Uses a white ruler.
  • Black: Uses a black ruler.
  • Yellow: Uses a yellow ruler.

Orientation Marker​

The Orientation Marker menu controls the marker used to show slice orientation. Marker type and size are synchronized across all three slice views.

Marker Style​

  • Off: Hides the orientation marker.
  • Unidirectional axes: Shows one-direction axes labels.
  • Bidirectional axes: Shows axes labels in both directions.
  • Cube: Shows a cube marker.
  • Human: Shows a body-orientation marker.

Marker Size​

  • Small axes size: Uses a smaller marker.
  • Medium axes size: Uses a medium marker.
  • Large axes size: Uses a larger marker.

Visibility Menu​

The Visibility menu controls overlays and slice-view display options.

  • Toggle slice in 3D view: Shows or hides this slice plane in the 3D view. Applies only to the current slice view.
  • View annotations: Shows or hides the corner annotations. Synchronized across all slice views.
  • Orientation labels: Shows or hides the edge-center direction labels (e.g. R, L, A, P for medical orientations or +X, -X for engineering). Shown by default. Synchronized across all slice views.
  • Color map bar: Shows or hides the color bar. Synchronized across all slice views.
  • Scene scale ruler: Shows or hides the scale ruler. Synchronized across all slice views.

Interpolation​

The interpolation mode controls how the slice image is rendered between neighboring voxels. This setting is synchronized across all three slice views.

  • Nearest neighbor: Shows the sharpest voxel edges with no smoothing. Use this mode when you need to inspect individual voxels precisely.
  • Linear: Smooths the display between neighboring voxels. This is the default mode for general use.
  • Cubic: Applies stronger smoothing for a softer slice display.

More Options​

The More Options menu provides view-management and background settings. Detach, fullscreen, and background changes apply to the current slice view only.

When the current slice view has focus, use Ctrl+Space to maximize or restore it, F11 to detach it, and Ctrl+Alt+Space to toggle fullscreen.

  • Detach view: Opens the current slice view outside the main layout.
  • Toggle fullscreen: Shows the current slice view in fullscreen.
  • Dark gray background: Sets a dark gray background.
  • Black background: Sets a black background.
  • White background: Sets a white background.
  • Choose background...: Lets you pick a custom background color.

Current View vs All Slice Views​

Some controller actions affect only the current slice view, while others are kept synchronized across all three slice views.

Current slice view only:

  • Center, Zoom In, Zoom Out, Screenshot
  • Flip (Horizontal, Vertical, Both)
  • Toggle slice in 3D view
  • Background changes, Detach, Fullscreen

All slice views (synchronized):

  • Ruler type and ruler color
  • Orientation marker type and size
  • View annotations
  • Orientation labels
  • Color map bar
  • Scene scale ruler
  • Interpolation mode
  • 2D Views – Slice view navigation and display behavior
  • Slice Views Tab – Ribbon controls for slice-view tools
  • 3D View – 3D display and slice-plane interaction
