3D Modelling is far more flexible than photography alone, and yet the result can still be incredibly photo-realistic. Models can be animated, or scaled and rotated etc. to meet the target medium, be it Internet, television, or print. The models can be viewed from different perspectives to give the audience a fuller picture. Also, for R&D purposes, a model can be created and analyzed way before the final product rolls off the shelves. This gives plenty of time for the marketing departments to push the product without having to wait until samples of it are available for an appointment at the photographers. In this final scenario, the model take on its own dynamics as pre-production alterations can be crafted into it, effectively developing it in sync with the engineering department. The result is a highly accurate representation of the final product - even custom alterations can be catered for so that the customer's own technical documentation can be held at the highest professional level reduce the numbers of calls to a support hot line.
