(32 x 32 x 256 x 256, 9.5 MB gunzipped)
Synthetic images drawn from a polygon model. The model was made from multiple range images using a volumetric method.
In order to view these light fields, you must first download lifview. Binaries are available for the SGI (Irix 5.0 or higher) and PC (Windows 95) platforms. Each light field listed below is labeled with the number of light samples it contains (u x v views x s x t pixels) and its compressed size (megabytes gunzipped).

Synthetic images drawn from a polygon model.
The model was made from multiple range images using a
volumetric method.
(8 x 8 x 256 x 256, 2.0 MB gunzipped)
A lower-resolution version of the same light field.
(16 slabs x 6 x 24 x 256 x 256, 18.8 MB gunzipped)
The dragon, with 16 slabs that allow full 360-degree sideways rotation.
(32 x 32 x 256 x 256, 8.8 MB gunzipped)
Synthetic images drawn from a polygon model.
This model was shaded to simulate a
metallic patina.
(16 x 16 x 256 x 256, 2.8 MB gunzipped)
The same model buddha4c, but with half the resolution in u and v
(assembled from 1/4 as many images, with twice the synthetic aperture).
(16 x 16 x 128 x 128, 2.1 MB gunzipped)
The same model buddha3c, but with half the resolution in s and t
(generated from images 1/4 the size used in buddha3c and buddha4c) .
(64 x 64 x 128 x 128, 9.5 MB gunzipped)
Volume-rendered light field of two kidneys, spine, and blood vessels.

Synthetic images from U.C. Berkeley
Soda hall
walkthrough.
(4 slabs x 32 x 16 x 256 x 256, 16.8 MB gunzipped)
Digitized images captured with a video camera and computer-controlled
gantry. The camera aperture was too small
for the view spacing, producing aliasing.
(16 x 16 x 256 x 256, 8.1 MB gunzipped)
Digitized images captured with the same gantry
used for the lion above. In this lightfield, the st-plane passes near
the magnifying glass.
(16 x 16 x 256 x 256, 8.1 MB gunzipped)
Same as crayons2, except the st-plane passes through the crayons.
Here are a few sets of the original images, before they were compressed into a .lif file. Each tar.gz file contains the original .rgb images and the .lid (light field description) file that specifies the geometry and general information about the light field.
Note that these raw lightfields can be viewed by running the SGI version of lifview on the .lid files. You can run side-by-side comparisons with the compressed .lif files above to evaluate the effects of the VQ compression.

The raw images and .lid file for the low-res version of the dragon
light field. Lifview can display this light field on systems with
64MB of memory.
(32 x 32 x 256 x 256, 100 MB gunzipped)
The raw images and .lid file for the high-res version of the dragon
light field. Lifview requires more than 256MB of memory to view this
light field.
(32 x 32 x 256 x 256, 45 MB gunzipped)
The raw images and .lid file for the high-res version of the buddha
light field. Lifview requires more than 256MB of memory to view this
light field.
(4 x 32 x 16 x 256 x 256, 80 MB gunzipped)
The raw images and .lid file for the 4-slab, 360-degree lion
light field, which was captured with a video camera and
computer-controlled gantry.
Lifview requires more than 512MB of memory to view this entire
light field. (A single slab can be viewed in 256MB of memory).
