what are the v.in.ascii command line options you are using?
what version of GRASS?
why format=standard not format=point? If using format=standard you need
to use the special format described in the v.in.ascii help page.
it should look like:
v.in.ascii in=points.txt out=new_map x=1 y=2 z=3 -z fs=, format=point

Look at the v.surf.* modules. (technically a raster surface not a TIN)

r.shaded.relief or NVIZ.
