drapeing images

Lyman_Barger · January 8, 1997, 5:12pm

Question:

I am using GRASS 4.1 on an SGI INDIGO2. I have two raster images( one from x,y
with z and another scanned raster). Both are good raster images. What method
should I use to drape the digitized image over the x,y,z image?

You're lucky, Lyman. Since you're working on an SGI box, you have access
to the program sg3d, which does an outstanding job of creating image
"drapes". Enjoy!

Hi,

Question:

with z and another scanned raster). Both are good raster images. What method
should I use to drape the digitized image over the x,y,z image?

If both images are referenced you should think about to use or d.3d
(normal X) or SG3D ( a Silicon tool available on moon). If you stil have
to reference both images to each other you should check

http://taoren.rug.ac.be/~bart/paper/paper.html and check the part on
coordinate systems and transformations!
