How did renaissance scientific advances have artists to make more realistic art

The development of knowledge in the XIV-XVI centuries significantly influenced the representation of people about the world and place of man in it. The great geographical discoveries, the heliocentric system of the world Nicholas Copernicus changed the idea of the size of the earth and its place in the universe, and the works of Paracelsus and Visalia, in which for the first time after antiquity, attempts were made to study the structure Human and the processes taking place in it, have begun scientific medicine and anatomy.  

The painting of the Renaissance is characterized by the appeal of the artist's professional view of nature, to the laws of anatomy, life perspective, and other natural phenomena.  

Artists of Renaissance, drawing pictures of traditional religious subjects, have started to use new art techniques: the building of a volumetric composition, use of a landscape as an element of a plot in a background. This allowed them to make the images more realistic, lively, which showed a sharp difference in their creativity from the previous iconographic tradition, replete with conventions in the image.
