I am involved in a school project that it will involve creating a virtual image (or projection). It will involve having several layers or pieces of imagery. It will actually be putting together a data-center structure. The first thing that comes to mind is utilizing (MS Project and or VISIO) some type of autocad program, even Powerpoint. I don't have much experience with this type of software, is there any recommendations out there, that may help? I would like to make a presentation as realistic as possible.
