What technique added depth to paintings during the renaissance?

During the Renaissance, the technique of linear perspective was introduced, which added depth and dimension to paintings. This approach involved creating a vanishing point on the horizon line, where parallel lines appear to converge, giving the illusion of space. Artists like Filippo Brunelleschi and Leon Battista Alberti developed this method, allowing for more realistic representations of three-dimensional space. Additionally, the use of chiaroscuro, the contrast between light and shadow, further enhanced the sense of depth in artworks.
