I'm doing a Masters degree in CAD and Construction and as part of my Realtime CAD assignment i decided to learn and use the Crysis Sandbox editor to create an architectural visualization. The assignment was to create an interactive architectural environment in an engine of your choice.
This was my first time using Crysis, as i had previously used the unreal engine, I managed to produced a whole island and also managed to import an architectural model into the engine. I was surprised at how easy and user friendly Crysis sandbox is compared to other architectural alternatives. I manged to to do this pretty quickly and had loads of fun in the process. the whole island and architecture model was done within a 4 days( in between my off days from work) It isn't totally finished but i ran out of time and did the presentation as it was just meant to be a test excercise. They were very impressed with the quality of Crysis, and the other examples created in Vizard and Quest 3D just paled in comparison to what this can do.
this was just a quick test and i am working on some more advanced examples.
you can see a few examples below, To see more images you can check this flickr set at the following URL
