To create a demonstration model for you or your customer, you have several options. (Clickable) Mockup: A mockup represents the content and functionality of your project in static form. You work out the visual elements of your website so far that the representation already resembles the final product. However, you can expand your mockup by, for example, already integrating the menu bar and the footer and making them clickable. 3D Mockup: A 3D mockup is used for the representation of products. Tools such as the Creative Cloud from Adobe already offer a pre-selection in the library, which only needs to be individualized. In agencies, 3D mockups are often used to show the customer how his website can look on different devices. You also know 3D mockups from the area of online shopping.
