Which technique did renaissance artists use an artwork?

Painting in the renaissance was most commonly done as fresco or murals painted onto plaster walls. For frescos pigments were mixed with water and directly painted onto the wall. However some artists did paint on wood using tempera paints which are pigments that use egg yolk as a binder

Perspective is important because it enabled the 3 dimensional world to be translated into the 2d world of the picture plane. this had an immediate impact on the representation of reality in art and design.
