To avoid reinventing the wheel we looked at the research and documentation done on topics related to our design problem. We started off by looking at ’Äú3D’Äù, ’Äúfile hierarchy’Äù, ’ÄúOrganization’Äù, ’ÄúNavigation’Äù etc. After doing some Contextual Inquiries, we identified a number of problems (*?). We ranked the problems in the order of severity and number of occurrences and changed the focus of Literature Review to include topics like Versioning and 3D Perception. Presented here is a gist of what we learnt from some of the selected papers.
