Cone of Vision
In order to understand what the "cone of vision" is, please watch this short video.
People have an approximate 60-degree angle of undistorted vision that extends as an imaginary cone from their eyes forward. Outside of the 60-degree angle, objects begin to blur. In linear perspective, the Cone of Vision is indicated with a 60 degree angle beginning at the station point it is 30 degrees to the left and right of the line of sight. In Linear Perspective, the proportion of objects drawn outside of the Cone of Vision become distorted. This represents the blur we see with our eyes.

If the VP1 and VP2 is kept/drawn on the 9"x12" format it will limit your cone of vision. Anything drawn outside of the cone of vision will be distorted. |
