for the digital animation industry is nessesary to have an easy-to-used 3d software. how easy the user is able to interact with it is very important. the pop-out effect is one of the most important feature channel for software interfaces. the user has to be able to identify the different Hierarchies of what he is trying to interact with. A good example is the maya 3d software interface, as we can see in the interface the tool bars are easy to spot. the main menus are cluster next to each other creating visible area, the blue color makes them easy to spot and use. the tool bars are right next to the main interactive part of the interface for easy and fast interaction. then you can see that there are different Hierarchies on the interface since there are smaller tool bars that are second because they have less interaction in the interface. the designer made the main tools ore conspicuous for easy use.
