Name
vie — Viewport handling
...
Viewports are rectangular sub-areas of the screen or a plot.
Arguments
nx ny number
Make nx times ny viewports and use viewport number number as the active viewport. Default, the present display will be moved to the lower left viewport. If you do not want that display, erase it.
number
Select viewport number number.
def
Erase all viewports and reset to one viewport (the whole screen).
del [number]
Delete active viewport [or viewport number number].
next
Go to next viewport.
pre
Go to previous viewport.
number | next | pre con
Connect camera from present viewport to the number | next | pre viewport. This will make the viewports suitable for parallel display of two datasets.
1 1 1
Create an initial viewport for coordinate selection.
coor x1 y1 x2 y2
The coordinates are in virtual display coordinates from 0 to 1. x1 y1 is the lower left corner, x2 y2 is the upper right corner left. NB! Needs a vie 1 1 1 viewport as a base.
con
Will connect the viewport camera to the previous.

# One can copy geometry to scalars and then to another
# scalar set of another surface thus displaying
# one surface as scalars on top of another.
vie def ;# reset viewport
ret 10 ;# return start window
vie 2 2 1 ;# set up 4 viewports, select first
mak ran 11 ;# make random points
grp 70 70 ;# make grid and scalars
ssc ;# self scale
mak p ;# transform grid to polydata
acm n 11 ;# map display
mhi grid1 ;# move grid to hi grid1
vie 2 con ;# select viewport 2 and connect to previous
mak ran 11 ;# make new random points
grp 70 70 ;# make new grid
mak p ;# transform grid to polydata
acm l ;# map display
mhi grid2 ;# move grid to hi grid2
vie 3 con ;# select viewport 3
mak rsc grid1 ;# replace scalars from grid1
acm l ;# map grid1 on top of grid2
con l ;# contour grid1 on top of grid2
vie 4 con ;# select viewport 4
map ;# map grid1 on top of grid2
con l ;# contour grid1 on top of grid2
