Which explains how giotto changed the way that art looked? he began to use shading to create depth and dimension in his paintings. he changed the way people were painted by showing human anatomy under loosely draped clothing. he revolutionized the use of space, light, and color to create vivid images of people. he rediscovered the use of perspective by creating a vanishing point in his paintings.

Giotto changed the way art looked because he revolutionized the use of space, light, and color to create vivid images of people. He was able to portray realistic and expressive postures and gestures, architectural spaces that looked surprisingly tridimensional (and, therefore, realistic, convincing, believable), a dense light that could almost be touched, and rich and luxurious colors that are a feast to the eyes of the viewer. For all those reasons he is considered the most important Italian painter of the 14th century (and there were many good artists working in that century) and the precursor of the innovations that took place in the Renaissance.
