 Since one month I am working on a GRASS 6 inorder to view my data in 3 dimension ISO Surface 
 I am using V.Vol.RST for interpolation but I don't get results....I always get error messages:
 
 
 v.vol.rst input=octVector cellinp=survoctVector wcolumn=dbl_4 tension=40. smooth=0.1 segmax=50 dmin=0.010000 npmin=200 wmult=1.0 zmult=1.0 elev=ccc 
 
 65536 records selected from table
 
 Points are too concentrated -- please increase DMIN

 finished interpolating
 
 I have dbf vector file composed of 5 columns : CAT, dbl_1 (lat) , dbl_2(long), dbl_3(Sea Depth), dbl_4 (Temprature)
 
 following under is sample of my data:
 
 60.394146|-60.344543|-38.880001|5.940000
 60.394146|-60.344543|-39.080002|5.944000
 60.394146|-60.344543|-38.980000|5.945000
 60.394146|-60.344543|-38.980000|5.946000
 60.394146|-60.344543|-39.080002|5.949000
 60.394146|-60.344543|-38.980000|5.951000
 60.394146|-60.344543|-38.980000|5.951000
 60.394146|-60.344543|-39.080002|5.951000
 60.394146|-60.344543|-38.880001|5.953000
 
 actually , I don't know from where to start, I already transfer my data to vector  as above...I can see my map ..but what I need next to visualise the map in 3 dim...I have read many articles..but I dont get any advantage......I dont know
  So far , I don't have any output,,please tell me what should I do.
 
 many thanks
