3D models are imported from CAD files or created from sketches and engineering drawings to produce realistic renders and animations. In addition, there is an extensive library of royalty free, high quality 3D models, which are used directly or incorporated into scenes to provide added detail and realism at little extra cost. Virtual models and animations are combined with real world footage to create visually accurate depictions of finished projects when still at the planning and prototype stages. Time and money is saved by identifying potential problems, in a virtual world, for a tiny fraction of the overall project budget. In addition to functionality, product aesthestics can be explored at length and in great detail. Once the model has been created, adjusting colour schemes and texture maps is relatively straightforward to implement.
