Steps to Display Data onto Biowall

(Still a work in progress to upload directions to this page)

Startup shortcut icon is on the Desktop of the controller computer, found to the right of the biowall.  (aka "start CGLX")

Data can be left on network tera drives - no transferring to special drives necessary

All tifs must be in single directory.

push "start" on CGLX to have a clean start.

Click on "File --> open" and open the start file to initialize the tile wall.

Open Input Files points to data directory e.g. tera5

In miniwindow on CGLX, a display of your data should appear. 

Hit start on miniwindow to upload display to biowall.

Opening TIF images

Double click on the "convert images to wall tif" icon to convert images

Select the data directory where the tif images are held

Choose an output directory

Click on "start"

Until images are converted, the biowall will refuse to display any data.

Hotkeys

  • F12: toggles images through continuous slideshow and out of slideshow
  • F11: tiles the images across a 2D plane
  • Up and down buttons affects speed of slideshow
  • F10: reset button
  • Esc: exits out of CGLX program

Notes

  • Will accept most known 2D image types except for 16 bit grayscale
  • Can display "small" (<500 mb) files without converstion to biowall format
  • Will accept and display mpg-1 and mpg-2 as well as quicktime .mov files.  Will not correctly display .avi at this time
  • Will accept most 3D models e.g. .obj, VRML files, etc, but will only display one model at a time
  • Conversion costs of images to biowall format:
    • 1.4 X file size
    • ~30 to 60 seconds time to convert 1 GB image files. 

Known Issues

  • As of September of 2009, the biowall cannot display 16 bit grayscale images.  Convert all grayscale images to 8 bit before using on biowall
  • Will not display MRC format files. 
  • Will not display .avi nor .mov at this time.  Convert movies to .mpg.
