[GRASSLIST:1956] Re: Tasseled Cap Vegetation Index

[ziyadin]

Dear all,
I have a DEM file in grass raster format. I have also imported a ppm
image as 
a raster file and I can visualise it wiht d.raster without any problem.
Now I want to drape this image over my DEM.
I have being trying to figure out how to do it using nviz. 
I have checked the grass mail list archive but not much help.
It seems nviz accepts sites or vector file to drape. I converted the
image
to sites file (r.to.sites) and tried to drape but no success.
I would appretiate any hints. 
Thanks,
Ziya
