1. Kejun Dong, Yihua Zheng @ CNIC Elaine Liu, Jurgen Schulze @ UCSD CNIC Tiled Display Wall and Astronomical Data Visualization PRAGMA11 Workshop Oct.16/17 Osaka, Japan

2. Outline CNIC Tiled Display Wall Astronomical Data Visualization

3. Tiled Display Wall @ CNIC A Tiled Display Wall (TDW) is a large- scale high-resolution display CNICs TDW is setup at 2005, supporting by Chinese Academy of Science. Uses a five by four grid of LCDs and 21- nodes cluster running Rocks (with CentOS installed). 1Gigabit network for each node.

4. LCD grid ViewSonic 17 LCDs

5. 1+20 Cluster IBM xSeries 226 Server –Xeon2.8GHz –1G Memory (frontend 3G) –Dual Gigabit Network –73G SCSI Harddisk –Nvidia 128M Video adapter

6. Visualization Software Package Rocks Viz Roll – SDSC SAGE - EVL/UIC

7. Rocks Viz Roll DMX - Distributed Multihead X http://dmx.sourceforge.net/ Key Soft –Xdmx:a proxy X server that provides a multi-head support for multiple displays attached to different machines. –Chromium:a system for interactive rendering on clusters of graphics workstations –Cg:nVidia Toolkit

8. Applications Based on Rocks Viz OpenGL App –QMView –PyMol –VMD –ParaView Image Viewer (not very well) –xnview, gthumb, ImageMagic

9. PyMol

10. xnview

11. SAGE Scalable Adaptive Graphics Environment SAGE is a graphics streaming architecture for supporting collaborative scientific visualization environments with potentially hundreds of megapixels of contiguous display resolution. Key Soft –QUANTA, Readline, SDL, GLUT –SAGE/Sage UI

12. Applications Based on SAGE Image Viewer –JuxtaView, imageviewer(10kx10k), Magic Carpet OpenGL –Qmview Video Viewer –MPlayer Collaboration –VNCViewer Others –Rasmol, lambdaCam

13. JuxtaView 633M

14. OpenGL App

15. Others MPlayer VNC

16. Astronomical Data Visualization A PRIME 2006 Project –2006.6-8 –Supported by NSF –Using CalIT2 TDW and CNICs TDW –Finished by Elaine Liu (UCSD) at CNIC To remotely visualize high resolution astronomical images on UC San Diegos tile display wall while controlling at CNIC and to gain more knowledge about astronomy.

17. Software & Data Software –SAGE –JuxtaView Server –JuxtaSCUI/SAGE UI Astronomical Data –SDSS –DSS –Data from NASA

18. Data Processing FITS Images JPG Images TIFF Images (continuous Images) ImageMagic/Photoshop

19. Image made from stitching up 16 smaller images together

20. CNICs TDW using SAGEUI Monitoring CalIT2 TDW with LambdaCam CalIT2 TDW with LambdaCam

21. Next in Astro Visualization… Fits data remote display Arranging images automatically and Stitching them up
