I'm not trying to compare which one is the best among the photograph & 3D visual..but with the latest technology in CGI, we can predict almost 95% of the final outcome even before it has started @ build. Thanks to the Vray team ( Chaos Group ) for such a brilliant software that make both of my boss & client happy... :D
Off course the 3D visuals was just an initial design from my designer, things change when it comes to sites, unexpected problems with M&E terms, actual lights behavior, clients instant ideas, pricing and such....
