3D modelling is an innovation that is widely used in product development. Its applications are many and varied, from industrial and architectural design to gaming and movie animation. 3D modelling allows designers to create realistic images of their products, which can be used for marketing or testing purposes. It can also be used to create virtual prototypes of products, which can be tested for safety and durability before they are manufactured. 3D modelling is a powerful tool that can help businesses save time and money by reducing the need for expensive physical prototypes. It is also an invaluable tool for educators, who can use it to create models of complex concepts that are difficult to illustrate with traditional methods.
