r.refine's Issues

wish to move this module to grass-addons

Dear author, it would be useful to move this module to GRASS-Addons [1]. Then your module would be simple for the user to install it via g.extension [2] including Windows binaries. Thanks, Martin

Output TIN is alwasy 8 triangles and 16 points

Hi,
I've just found your executable. I've compiled it and I'm trying to use it on a 3404*2404 ESRI Ascii grid.
I've launched it with:

./r.refine dtm.grid dmt.tin 1.0

The output is:

Assuming Delaunay is on.
Assuming no to handle nodata points
total size per point=50
TL = 1619
numtile=[2, 2]
refining..
done refining
.......DONE........
err=1.00% absErr=-99.99  mem=250.00MB numTiles=4
raster: 7702416 points
TIN: triangles=8 points=16
total time: 0.33    99.9%

And I get the same triangles and points even if I change the error (from 0.1 to 10)
Trying to render it doesn't show anything....
What am I doing wrong?
