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.
1. Linear Perspective-By using either 1 point perspective, 2 point perspective, or 3 point perspective, an artist can create the illusion of space. Linear perspective is a drawing method that uses lines to draw objects in space. 2. Overlapping-When one object is positioned in front of another object, part of the object behind it may be blocked from view. This is called overlapping.
