[GRASS-user] create 3d plane from vector lines

Hi all,

I'm stuck here, trying to create 3d vertical surfaces from 2d vector
lines (to represent faults in nviz). hints?

TIA

Carlos

Hi Carlos. You can use v.surf.rst. Description (from command help):

“Spatial approximation and topographic analysis from given … isoline data in vector format to floating point raster format using regularized spline with tension.”

Basic usage (remember to adjust region settings):

v.surf.rst input=contour layer=0 elev=surface

Where:

contour : name of the map containing your vector lines (iso lines or level contours).
surface : name of the raster map, obtained from interpolation of the vector lines.

More info here: http://grass.itc.it/grass62/manuals/html62_user/v.surf.rst.html

I hope that this help you.

Hello José.

v.surf.rst is not exactly what I want here, although I could duplicate
my vector lines with different elevations and then interpolate the
values to get _raster_ surfaces. I was thinking more in a v.extrude
way, just that it currently extrude areas to form facets or shifts
lines, but it doesn't create planes from line (AFAICT).

cheers

Hi Carlos,
how about using v.delaunay?
If you have two lines for each fault, you can triangulate the space in between.
But im not sure if this works with vertical lines.
If you export those lines to VTK, you can triangulate vertical planes
with the VTK delaunay triangulator in ParaView.

Thanks Soren, I got the effect I wanted in Paraview, using the "linear
extrusion" filter.

Hey pal,

does that method allows for representation of dipping surfaces?
You know you should think about that too =]

Hey Mate,

you know, simple dipping surfaces are easy, r.plane will do the job,
but _complex_ dipping surfaces (like real faults) are still a work in
progress..

cheers
