For instance "Greater London"? Message-ID: I need to make a good estimation of how many megabytes or gigabytes would be a file in the format of VRML 2 (extension .wrl) in a static text file for the 3D representation of a kind of Google 3D map of "Greater London (Zone 1 to zone 6!)", in the United Kingdom, given that that representation would only use the box (parallelepiped facade) and would be a bit like the plaster mockup in miniature of an urban city of an architect in reasonable accuracy featuring buildings and their facades (that are not particularly high) and the large amounts of roads and parks that are basically empty... How many gigabytes would that static text file in .wrl format be? Roughly. A good estimation is needed. You can calculate it for a good area neighborhood and then multiply it for the whole area or something like that. Just assume there are no buildings like the Shard and ignore that level of finesse in the details of the facades of the buildings. We want a quite rough estimation to have an idea of how big would be the static data of the textfiles. If you can come up with a number with your own rough calculations in a couple of minutes would be indeed helpful. Would you say the .wrl file would be bigger than 1 Gigabyte for London (Zone 1-6)? Would you say the file is between 1-500 Gb? What is your best quick rough estimation? That will be helpful and I will, later on, be willing to compare notes if I do other calculations myself. - Daniel Alexandre -------------- next part -------------- An HTML attachment was scrubbed...
