- Vanishing points – linear perspective
Linear Perspective
The mathematical model of the visual pyramid. All sets of receding parallel lines converge to a unique vanishing point in the image. Horizontal lines converge to vanishing points on the horizon, vertical lines may converge to zeniths or nadirs.

Some ideas for student work were generated during the breakout session and are at Depth and Perspective Questions.
