Volume visualization for large, potentially time-varying, datasets on high-resolution displays (9Mpixels LCD panel, projection or LCD based tiled display, ...), refered to as "Vol-a-Tile".

This document proposes to report development and progress of the "Vol-a-Tile" system.

The following items are to test-crash the pipeline from raw data file stored on disk to the display. The usual steps are normalizing, converting to usual datatypes, downsampling, storage, network transmission, and insertion into the 3D pipeline for display.

Usability of the UI (transfer function, ...) is also examined.

Only single-display image are provided so far. Tiled-display iamges coming soon...

New screenshots on MacOSX (July 10, 2004):

	"Bonzai" dataset
	"Ranvier" dataset
	"Arad" dataset

Test datasets:

• Bonsai:
  • Raw: 256 x 256 x 256 volume, "unsigned char" type, 16MB
  • Comment: very easy to classify, clear cut between the different components

   

   

• Arad:
  • Raw: 1001 x 801 x 801 volume, "float" type, 2.5GB
  • Processed: 512 x 512 x 512 volume, "unsigne char" type, 128MB
  • Comments: large dataset downscaled, normalized to [0..1], converted to "unsigned char", and gaussian filtered to remove some noise (?).

   

   

• Jurassic tank:
  • Raw: 440 x 290 x 148, "unsigned char" type, 25MB
  • Processed: 256 x 256 x 256 volume, "unsigned char" type, 16MB
  • Comments:
