[GRASS-user] How to join 3D object to database

[Stefania Merlo]

Dear all,

still working on my 3D GIS for archaeological excavation. So, I  
managed successfully to create 3D vector
solids that represent archaeological strata (or contexts or layers, as  
you prefer) with a combination of creating upper and lower surface  
TINs in GRASS/Meshlab and joining them within 3D StudioMax (I have not  
found an Open source solution easy enough for me). I have imported the  
solids in GRASS, they seem to import nicely and they well visualise in  
Paraview. With the fact that they have to be handled as a combination  
of 3D faces rather than a unique solid, I am now facing a difficulty.  
How do I link the solids to my context database (which was given to me  
in Access but I have transformed into a simple cvs file)? Is the only  
solution that of linking the same context to all the single faces of  
my GRASS solid (in same cases more than 200/300)?

Has any one have any idea on a possible solution?

Thank you in advance.

Stefania
