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?
