Arbitrary dimensions, continued
For demonstrating 3D objects we chose a tomogram scan with the domain [0:255,
0:255, 0:153]. Since a computer screen is a 2D object, visualising data
with more than 2 dimensions calls for projections. In this example RasDaView
downloaded the entire 3D datacube and then displayed its contents using
simple orthogonal projections which would be described as
[dom_1,
dom_2, dom_3] using RasDL's trimming operator, where
exactly one of the dom_i is a single number which determines
the position of the plane to project to and the other two domain descriptors
are "*:*".
Here are thumbnails of three projections along different axes of the
data cube. The leftmost image was created using RasDaView's equivalent
of the
[*:*, *:*, 75] operator, the middle image using the equivalent
of [*:*, 90, *:*] and the rightmost one using the equivalent of
[128, *:*, *:*]. Click on each image to download the full-sized
