Three-dimensional work of art may be any paintings or geometric shapes that give an illusion of being the real thing with its height, width and depth in the viewer’s mind. The texture of the art work is also important. Looking at the work of art, the beholder has an illusion that the object or being is true to life. This is created by having shadows to the object, or playing with the lights.  Ideas and emotions are expressed through three-dimensional art works.
Sculptures also come under the category of Three-Dimensional art work.
