3D Visualisation - Products.
All product design, development & marketing can benefit greatly from 3D Visualisation.
The list of benefits to using 3D Visualisation for products is long; here's just a few points:
Whether it's for trialling a range of colours, textures, etc. or pre-visualising your design before production, it just makes sense to simulate your idea as part of the design process.
  Then there's the process of garnering buyer or investor interest before a product design is finalised, and of course marketing; 3D imagery is commonly used to produce stunning images of a product in favour of the limitations imposed by traditional photography.
