Dear colleagues

I have a text file with several columns representing (x,y,z) positions and corresponding values of Digital Volume Correlation (DVC) measurements. I would like to visualize in 3D the spatial distribution of these values.

The way the (x,y,z) coordinates is organized derives from a simple loop:  
count = 1;  
step = 2;  
imin = 40; imax = 309;  
jmin = 30; jmax = 70;  
kmin = 40; kmax = 220;  
for(i=imin; i\<imax; i=i+step){  
for(j=jmin; j\<jmax; j=j+step){  
for(k=kmin; k\<kmax; k=k+step){  
write(count + “\t” + i+ “\t” + j+ “\t” + k);  
count = count+1;  
}   
}  
}

Then, for each (x,y,z) there are several associated measurements (u,v,w). I would like to plot u and/or v and/or w in 3D according to the (x,y,z) points.

I was able to read the txt file in Paraview and found a tip to use the Table to Points filter. I then tried several types of plots, but could not get a good graphical representation.

Any hints? Thank you!
