🗺️ParaView
Overview
For R&D 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 the open-source, multi-platform data analysis and visualization application ParaView.
With ParaView, researchers studying complex 3D fields like computational fluid dynamics, climate science, aerodynamic design, and materials science can now visualize and analyze their complex 3D data holographically as they work.
To learn more about ParaView, visit paraview.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 nightly builds of ParaView since Oct 1, 2020.
Kitware has prepared an easy to follow tutorial for setting up ParaView in the Looking Glass for the first time:
Example Data
See note below on how to load the example data into ParaView.
Data
Image | Description |
Airflow past a motorbike Output from a standard OpenFOAM example of airflow past a motorcycle and driver. The state file shows streamlines tracing out the direction of flow past the motorcycle. | |
LiDAR capture LiDAR capture featuring a field with powerlines, foliage, and buildings. | |
Airflow driving by heated spinning disk This dataset is a simulation of airflow driving by a heated spinning disk. Streamlines trace out the airflow in the data. Cone glyphs show the direction of airflow. Glyphs and the bounding surface (cut away to provide context) are both colored by temperature. Data provided courtesy of Sandia National Laboratories. | |
Impact of asteroid in the ocean This is a subset of data from the Deep Water Impact Ensemble Dataset simulating the impact of an asteroid in deep ocean water. NASA's Planetary Defence Coordination Office is keenly interested in knowing the lower size limit of dangerous asteroids. Data provided courtesy of Los Alamos National Lab: John Patchett and Galen Gisler. Deep Water Impact Ensemble Data Set. Los Alamos National Laboratory tech report LA-UR-17-21595. February 14, 2017. |
Loading the Data
Download and unzip the above datasets to view. To load into the Looking Glass:
In ParaView, Select File -> Load State
Browse to and select the .psvm file, and click OK
For Load State Data File Options, select Search files under specified directory and leave the Data Directory field default (the same directory as the .psvm), and click OK.
Once loaded, press the Render Active View on Looking Glass button in the Looking Glass panel
On occasion, the content may load behind or in front of the default clipping planes. Click Reset to Center of Rotation to recenter content
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 ParaView 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
Scroll the scroll wheel up and down - scale the scene larger and smaller
Right click and drag - move the camera forward and back
Looking Glass Panel Controls
Render Active View on Looking Glass
Display current view in ParaView in the connected Looking Glass display.
Reset to Center of Rotation
Recenter the Looking Glass capture volume to the center of rotation. Learn more about ParaView's concept of center.
Push Focal Plane Back
Push the focal plane of the Looking Glass backwards in the camera's Z space.
Pull Focal Plane Forward
Pull the focal plane of the Looking Glass forward in the camera's Z space.
Focal Plane Movement Factor
How much far forward and backward the above two buttons move in the camera's Z space.
Device Index
The index of Looking Glass device the ParaView image is sent to.
Rendering
Changes the refresh settings of the rendered Looking Glass 3D scene.
Always - render view refreshes in realtime
Only Still Renders - render view refreshes when user pauses
Only When Requested - only refreshes after user selects "Render Active View on Looking Glass"
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
For further ParaView support, visit the ParaView Forum.
Show us your work!
We are deeply excited about supporting the science 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!
