[GRASS-user] TIN (Linear interpolation) from points

In the past there was a module which created TINs from points as input in
GRASS, but now it is not longer supported:
http://www.grass-kr.org/html/v.geom.html

For me this part is very interesting: MaxMin-Height triangulation
But the last GRASS version which is supported is Version 5.4 .

I easily created a TIN with 3 points in QGIS in a couple of seconds. Is
there an possibility in GRASS GIS,too?
I don't understand why it is still not integrated into GRASS GIS (This
application is much older than QGIS?)

The possibility of automation in GRASS GIS via shellscript is the main
reason why i need GRASS.

The (Elevation-)TIN should look like this:

After the TIN creation I want to use the r.contour module to get contours
out of the TIN.
