Mechanical Perspective: a method of depicting a 3-dimensional (3-D) space on a flat surface using vanishing points.
Recede: to move back or away.
Picture Plane: the surface of your image. Literally the paper (or whatever material) you are drawing on, painting on. etc.
Horizon Line: an imaginary line where sky meets ground. Also, eye-level.
Vanishing Point: an imaginary point in space where all things seem to disappear.
Orthogonal Line: perspective lines that point to the vanishing point.
Using a single vanishing point on a horizon line, render the following shapes as 3-dimensional forms. Be sure to cut off each form; do not let them run on infinitely. Erase any unneeded lines and try to avoid ghosts.
Fix This Drawing
Below is a crude image that is two-dimensional. You are to redraw this image using the rules of perspective so as to make everything look three-dimensional. Some items can be drawn and then corrected. Some items must be corrected from the start.
Be sure to set a horizon line and a single vanishing point for all of your objects to be set to.
If you need some help on this at home, here is a decent website with a refresher.
Assessment: graded for correct and accurate use of mechanical perspective. This is a formative grade.
