Terminology:

Both picture and ground plane are infinite.


Where the center line and the picture plane intersect this is the center of vision and one point perspective that will be the vanishing point.

Bottom of the picture plane is the ground line. It will be a horizontal measuring line.

Cone of Vision: is the area you can see and draw undistorted. The farther you get away from the center of vision the more distorted it gets. The cone of vision is 60º, 30/30 on each side.
