Hi!
the image jpg in enclosure, is the result of the terrain that I have drawn beginning from the matrix of the altitudes. I would want to know if a way exists for not visualizing the quotas equal to 0.
the source code is found in the file morfologia.txt Thanks in advance. Aurora Restivo Jean-Christophe Lombardo ha scritto:
