3DIS4U

Stereo visualization

The acronym 3DIS4U stands for "Three-dimensional image studio for Uppsala" and is the Visualization Lab located at the Centre for Image Analysis at Polacksbacken, just opposite the Ångström laboratory.

As the name also implies (4U = for you), the visualization studio is available for anyone at the university who needs to visualize their data using a 3D stereoscopic display. The installed equipment use the modern INFITEC technology for 3D display, which really adds a new dimension to the data being displayed.

The closeness to the UPPMAX high-performance computing facilities adds another exciting advantage. In fact, the studio has a direct link to the Isis cluster. Thus, it will be possible for all researchers using the UPPMAX resources to run their applications on Isis and at the same time visualize the data being computed and interact with it in real-time.

Hardware

• Stereoscopic projectors
  • Two projectors with INFITEC filters and very good brightness for projecting stereoscopic images.
  • 25 Pairs of glasses required to view stereoscopic content which means that there can be up to 25 simultanious viewers.
• Two workstations
  • One with a powerful graphics card suited for real-time visualizations, running WindowsXP. Also got a fast connection to clusters provided by UPPMAX
  • Second workstation with two powerful processors and large amount of memory suited for preprocessing models for visualization or for visualizing larger models. This workstation is running Linux.

Software

The following software have been used so far, but it should be noted that we can try new software if required by you as a user: Milan GavrilovicMilan Gavrilovic

• The Visualization ToolKit (VTK) - Binds with Python for rapid development with high quality results.
• ParaView - For larger visualizations where the preprocessing and/or the rendering of the data needs to be distributed over several computers.
• Blender - Higher quality rendering of stereoscopic movies can be made with this software. Integrates with VTK and other software.

Contacts

• For technical question about the display or for support with visualization contact UPPMAX visualization expert, Anders Hast 
• Scheduling and reservation questions should be sent to the host for the seminar room at CBA, Milan Gavrilovic
