Documentation on views
Task: views
Purpose: Generate a projection of the datacube
Categories: visual display
VIEWS is a MIRIAD task which generates projections of a cube, viewed
as if the cube was rotating around its y axis. The view is also
from an angle "phi" to the x-z plane. The output is intended to be
fed into a tvmovie program, to view a rotating cube. The projection is
a thresholding operation -- pixels values less than the threshold are
transparent, a pixel greater than the threshold is opaque, with a
brightness given by the pixel value.
Key: in
Standard in keyword. Use `help in' for more information.
Key: region
Standard region keyword. Use `help region' for more information.
Key: out
Standard out keyword. Use `help out' for more information.
Key: phi
The elevation angle, with respect to the x-z plane, of the observer
(degrees). This must be in the range [0,90]. Default is 30.
Key: aspect
Aspect ratio of the different axes. Two values can be given, giving
the y/x aspect ratio, and the z/x aspect ratio. Default should be
fine.
Key: thresh
Threshold used in determining which details appear in the output.
Default is the average of the image minima and maxima.
Key: imsize
Size of the output cube. Default is 128x128x64 (should be adequate).
