as usual this is a psd work - no 3d.
i have created this presentation graphics for graphicriver.
the entire presentation is done using pscs4 and here i had exploited most of its new features like smart objects, feather on vector masks etc.
also there is an ps action set for hastle-free editting of the different surfaces - there are lots of layers as the whole presentation is done using only vector layers.
yes! there is no raster layer in this graphics so that the user can scale the graphics to any dimension of their choise and necessety.
if you love the design and want to incorporate them into your own design you can download the original psd from this [link]
there are two test renders of the second version of this presentation - [link]
