[GRASSLIST:5177] HELP

[Maria Jose Abasolo]

 Hi,
 
 I'm a new user of GRASS. I need someone to ask me
 the following:
 
 - is possible or usefull to use GRASS to store and
 manipulate images. What is the advantatge od using
GRASS instead just PostgreSQL? or PostGIS?
 
 - can I have several levels of an image, i.e. one 
 level with the original image, the other level
 with  color segmentation of the original image.
 
 - how can I add 3D scenes? does GRASS accept
 OpenGL or OpenInventor format?
 
 Many thanks in advance
