Hi,</div>
<div style="font-family:Calibri,Helvetica,sans-serif;font-size:12pt;color:rgb(0,0,0)">
Is there any clue that i can extract the row and column data from a csv file and read them as points?</div>
<div style="font-family:Calibri,Helvetica,sans-serif;font-size:12pt;color:rgb(0,0,0)">
Currently I am using <span style="font-size:16px;background-color:rgb(255,255,255);display:inline!important">
vtkpoints to </span>read points by inserting points manually to my .cpp .</div>
<div style="font-family:Calibri,Helvetica,sans-serif;font-size:12pt;color:rgb(0,0,0)">
Is it possible for me to call the csv directly and read the data (eg. column 3-5, row 2-10)?</div>
