1. A method for depicting multiple virtual elements in a display area of at least one display apparatus of a vehicle, wherein a three-dimensional space is depicted in the display area of the display apparatus, the method comprising:
determining, based on at least one data source, three-dimensional coordinates for locating the multiple virtual elements;
determining, whether the three-dimensional coordinates of each virtual element of the multiple virtual elements in the depicted three-dimensional space lie within the display area of the display apparatus or not;
for each first virtual element of a set of first virtual elements of the multiple virtual elements having three-dimensional coordinates that lie within the three-dimensional space depicted in the display area of the display apparatus:
transforming the respective first virtual element as a two-dimensional image in the three-dimensional space that is depicted in the display area of the display apparatus; and
depicting the respective first virtual element in the display area of the display apparatus in a correct perspective in a field of vision of a driver with respect to the three-dimensional space; and
for a second virtual element of the multiple virtual elements having three-dimensional coordinates that lie outside the three-dimensional space depicted in the display area of the display apparatus, visually depicting a virtual signaling element in the display area of the display apparatus to indicate the presence of the second virtual element lying outside the three-dimensional space depicted in the display area.
