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

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
