This website shows how angles come into art in museums. One painting might look realistic, but it doesn’t quite seem like it has depth. Another painting might not seem as realistic, but does seem like it is popping out of the canvas. This is because the second painting used the right ways to portray depth.
Triangles are places on the paper, and the vertices are the vanishing points. Vanishing points are when you can no longer see it because it is too far away. also, you can determine where the vanishing points are if you see parallel lines. Annalisa Crannell brings chopsticks to art museums to figure out how to view the art piece.
