you might have a look at Pavel Sakov's gridgen

I know you want to make a TIN, but really you probably don't need a
TIN at all.... there are much better ways to represent a surface and
while I'm ignorant of your plans I suspect that you'd just be making
extra work for yourself.

As mentioned earlier, you also might have a look at Laura Toma's r.refine:

which will reduce a DEM to a TIN.
