🗡️3D Slicer
Looking Glass support is only provided in 3D Slicer's Preview Release (unstable).
Overview
For medical professionals looking for ways to elevate the visual communication and comprehension of their work in 3D, Kitware, Inc. and Looking Glass Factory have integrated the immersive holographic displays with 3D Slicer, an open-source, multi-platform medical imaging application.
To learn more about 3D Slicer, visit slicer.org.
Getting Started
If this is the first time setting up a Looking Glass, visit the Getting Started page for your display.
This integration requires Looking Glass Bridge v1.1.3 or later. Use this diagnostic tool to check which version you have installed if unsure.
Looking Glass support has been added to preview builds of 3D Slicer since Oct 15, 2020. To download select the Preview Release version from the download page:
Kitware has prepared an easy-to-follow tutorial for setting up 3D Slicer in the Looking Glass for the first time:
Loading Example Data
Download and unzip the above datasets to view. To load into the Looking Glass:
First, in 3D Slicer search for the "Sample Data" module by clicking on the magnifying glass in the Modules panel.
Next, select any sample data set you'd like. Data prepended with CT tends to look best, tends to have better scanning resolution that MR or other formats.
Once loaded, switch to the Volume Rendering module (available in the pulldown).
Inside the Volume Rendering module, with your dataset selected in the "Volume" field, (1) select the eye tool. Then (2) change to a preset relevant to your data. Lastly, (3) adjust the shift so you can see the most of the model. NOTE Rendering should stay on GPU (not CPU) rendering.
Quick Reference
This reference covers all you need to navigate and control functionality specific to the Looking Glass.
For a comprehensive reference on all the features 3D Slicer has to offer, please visit the documentation on their site.
Mouse Controls
Place your mouse in the 3D view of the 2D interface to execute the following interactions:
Left click and drag - rotate the camera around the data
Scroll wheel click and drag - pan the scene
Right click and drag / Scroll wheel - scale the scene larger and smaller
Looking Glass Module Controls
Connect to hardware
Toggles whether or not connected to hardware.
Enable rendering
Toggles whether or not rendering is enabled
Rendering
Changes the refresh settings of the rendered Looking Glass 3D scene.
OnlyWhenRequested - only refreshes after user presses "Set looking glass view to match reference view."
OnlyStillRenders - render view refreshes when user pauses
Always - render view refreshes in realtime
Update rate
Rate at which 3D Slicer attempts to update the image on the Looking Glass. Higher rates are achieved by reducing render fidelity.
Set looking glass view to match reference view.
Renders the 3D view in the Looking Glass when OnlyWhenRequested is selected from the "Rendering" pulldown above.
Reference View
Selects which 3D viewport should render on the Looking Glass.
Focal Plane
Pushes / pulls the focal plane forward or back.
Uses clipping limits
Toggles whether clipping limits are enabled
Near Clipping Limit
Adjusts the near clipping plane of the rendered scene.
Far Clipping Limit
Adjusts the far clipping plane of the rendered scene.
Support

Show us your work!
We are deeply excited about supporting the medical visualization community in viewing their data in 3D on our displays. Please share video of the work that you do, either by tweeting @LKGGlass or emailing us at support@lookingglassfactory.com!
