Trees that grow from seeds start out as tiny seedlings, usually growing directly under the parent tree--the tree that dropped its seeds. Often, those seedlings die because they are blocked from receiving sunlight and moisture. However, seedlings raised in nurseries usually do very well, depending on the species of tree.
Italian Renaissance painters and architects including Filippo Brunelleschi, Masaccio, Paolo Uccello, Piero della Francesca and Luca Pacioli studied linear perspective, wrote treatises on it, and incorporated it into their artworks, thus contributing to the mathematics of art.
The linear perspective system projected the illusion of depth onto a two dimensional plane by use of âvanishing pointsâ to which all lines converged, at eye level, on the horizon. Soon after Brunelleshiâs painting, the concept caught on and many Italian artists started to use linear perspective in their paintings.
