can v.surf.bspline work with opint data imported as
v.in.ascii -vbt? I mean, without topolopgy nor table? Or I do need a
table?

just a guess, but yes, I think it should work.
Yes, Hamish, you are right. It actually works without topology. I doesn't care about it at all. Topology is not asked nor created in the case that vector output is used.
did you get an error?
Please, Carlos, let me know if you got an error. I'll use this long weekend (here in Italy) to fix already known bugs in v.surf.bspline and lidar modules.

Well Roberto, the first time I tried to run bspline it was in a file
imported without a table, and it crashed. Then I tried in the same
data but this time I imported it and created a table, and it worked
pretty well.
maybe just include in the help page that it can work without topology
but that a table is needed?

Hi Carlos,
Thank you for the information. I'll check it again because I've never had any problem of that kind. If I can't find anything extrange I'll add some line in the "bug" section of the help page.

In my first attempt to interpolate about 5mill points, 4mill cells and 10000 splines with my laptop (Centrino 1.6Ghz, 1Gb ram and 2Gb swap) I had no problem. I imported the vector as
v.in.ascii -z -t -b, that is, without topology and without create any table. So, are you sure it was a table problem?
Anyway, on Monday I'll check again with a more powerful computer and with much more points and splines and a higher resolution.
