When and why was the concept of perspective created?
- developed during the Renaissance
- meant to produce a true, visual geometry; the main object was to draw three-dimensional objects faithfully onto a two-dimensional canvas
What is the process called that involves drawing two-dimensional realistic pictures of three-dimensional objects on the drawing plane?
Perspective drawing
What are the four basic rules of perspective?
- The farther an object is, the smaller its perspective image is in the drawing plane
- Lines that are mutually parallel and parallel to the drawing plane are depicted as parallel
- Mutually parallel lines that are not parallel to the drawing plane are depicted as intersecting lines
- the intersection point is called the vanishing point - If three or more classes of parallel lines are all parallel to a fixed plane that is not parallel to the drawing plane, and if these classes of parallel lines determine three or more VP’s, then all of these VP’s occur on a single line
Exercise: Create a box in 1-point perspective, use a VP inside a square
Exercise: Create a box in 1-point perspective, use a VP outside the square
Exercise: Create a box in 2-point perspective
Exercise: Draw a box in 3-point perspective
Exercise: Draw a square in 2-point perspective
Exercise: Draw 4 squares of the same size forming a 2x2 checkerboard, using 2-point perspective
Exercise: Draw 9 squares of the same size forming a 3x3 checkerboard, using 2-point perspective
Exercise: Draw 16 squares of the same size forming a 4x4 checkerboard, using 2-point perspective
Exercise: Divide the given square into 4 equal squares of the same size forming a 2x2 checkerboard, using 2-point perspective
Exercise: Divide the given square into 9 equal squares of the same size forming a 3x3 checkerboard, using 2-point perspective
