How does the 2D image (picture) compare with the actual 3D object? When would the 2D image be more useful than the 3D? What gets lost or altered when a 3D object is represented in 2D? the 2D picture is of a computer
screen, showing a flat representation of a 3D object. The 2D image can only show one perspective of the object, whereas the actual 3D object can be viewed from multiple angles.
The 2D image may be more useful than the 3D object in certain situations, such as when precise measurements or detailed graphics are needed. It is also easier to share and distribute 2D images digitally compared to 3D objects.
When a 3D object is represented in 2D, some information is lost or altered. Depth perception is lost, as well as the ability to view the object from different angles. Details may also be distorted or misrepresented in a 2D image.
