Hello,
I am trying to create a 3D geological volume modeling. I have 5 geology
layers plus a DSM with a surface area covering around 1300 acres each. For
my test I clip a small subset of the area (10 acres) for each layer.
I set up up the g.region and then run the command r.to.raster3elev and I
also try r.to.rast3, but when i try to display the volumes They come empty.
Is there a step that I am missing?
Thank you,
David

Please tell us how you try to visualize...
- GRASS monitor
- GRASS wxGUI
- nVIZ
- via Paraview
...
thanks

Markus,
For the visualization part i am exporting the voxel into VTK so i can use Paraview. the result for using the r.to.rast3 or r.to.raster3elev are always empty.
Thank you,
David

Hello
In my experience, the problem lies in defining the upper and lower limits of
the 3D region (see

3D geological volume modeling (raster 3D): is it really possible ? )
with bad lower limit:

with appropriate lower limit

No problem with Paraview, but I am still unable to view it in nviz. I do not
understand the use of isosurfaces in this case.

Hi
My DSM goes upto 2300 ft and my lowest geology goes to 530 ft. So I set up my upper limit as 2300 and my lower limit as 500.
g.region t=2300 b=500 res3=1 tbres=5
Thank you,
David
