Hi,
I would like to display only a part of my topography (for example, giving
(xmin, ymin) and (xmax, ymax), it displays only the data contained in this
domain).
My data are on a regular grid. There is a 2D vector for the positions, and
a scalar for the altitude.
I tried :
Mark(positions)->Compute(a.x)->Include(xmin, xmax)->UnMark
but it doesn't work.
When I use the Describe module, it seems that the number of data has
correctly been reduce, but it is said that the input object has bad
positions. I suppose I lose data.
Could anybody help me please?
I think the proper way to do this would be by using a clip box.
Cheers
Jochen
