Dear all, I need some help here. I guess that my problem is kind of usual but I couldn't find a way to solve it yet. I have gone through some of the past opendx-user mail files and I couldn't find any help.
I have a collection of points which are x and y coordinates and elevation z. My initial data is scattered set of points with no connections: a 3 columns ASCII file. To start I Import the ascii file using a general file to describe it, then autogrid it and export it as a 'dx' format file. (The headers of the 'general' and 'dx' files that I created are at the end of this message). I managed to create a Rubbersheet with the dx data, autocolor and find the gradient of the surface. But now I would like to input the X and Y coordinates of some points and find out the corresponding Z value. Is this possible? If somebody could point me to the past emails that could help or give some hints or suggestions, it would be great. Thanks Jens General and dx files' headers: ************ general file **************************************** file = coordinates.xyz points = 933691 series = 1 field = locations, Z structure = 2-vector, scalar layout = 0, 13, 13, 13 header = lines 0 interleaving = field ============ dx file ============================================== object 1 class gridpositions counts 1217 769 origin 283770 1029430 delta 10.26316 0 delta 0 10.26042 attribute "dep" string "positions" # object 2 class gridconnections counts 1217 769 attribute "element type" string "quads" attribute "dep" string "connections" attribute "ref" string "positions" # object 3 class array type float rank 0 items 935873 lsb ieee data 0 attribute "dep" string "positions" # object 4 class array type unsigned byte rank 0 items 935873 lsb ieee data 3743492 attribute "dep" string "positions" # object "Z" class field component "positions" value 1 component "connections" value 2 component "data" value 3 component "invalid positions" value 4 attribute "name" string "Z" attribute "AutoGrid radius" number 20.526316 # end ------------------------------------------------------------- Jens Fernandez-Vega KW Ltd. email: [EMAIL PROTECTED] -------------------------------------------------------------
