<div>Hey,</div>
<div>I would like to create a 3D voxel model on GRASS of the resistivities in the ground. My xyz file is componed by:</div>
<div>x y z rho</div>
<div>At the moment, I have imported the file but I can not view the 3D vector point file with the NVIZ tool...when I want to visualize it, nothing appears although I can see it in the map display in 2D..</div>
<div>When I try to interpolate these points with v.vol.rst, it says to me that there are points outside specified 2d 3d region and that it is too long to find points for interpolation and so I should change the region to area where my points are...</div>
<div>Everybody has an idea?</div>
<div> </div>
<div>thanks</div>
<div> </div>
<div>If somebody have a proceeding for creation of a3D model from an ASCII point file with x,y,z,w, I should be very pleased to study it!</div>
