I need to collect some information about various things....so here goes.......

1. if anybody out there is working with CGI (computer generated imagery) systems, I would appreciate it if you could briefly outline what type of equipment you are using and the
application area that you are involved in.....( pretty general, heh???)

2. Does anybody out there take 2D images (a la satellite data) and map into 3D geometry...and then overlay the original image onto the 3D representation............
  I am really ignorant about available software and/or techniques....(so bear with me...)

3. One of the guys who came to pick my brain on these subjects (needless to say, he went
    away empty-handed!!!)....indirectly referred to something called "shade to shape"
     algorithms......does anybody out there have a reference to this flavor of algorithm
     ( I did do some looking.....computer vision, right????)


Any and all answers would be greatly appreciated.........Thanks in advance......
