Perspective!
Picture plane – Ground plane – the flat, two-dimensional, transparent surface on which we draw or project an image Ground plane – the flat, horizontal surface within the picture plane -think of the ground plane as the lake surface on which a boat sails, or the ground on which a building sits

Perspective drawing is the art of describing three-dimensional volumes or spatial relationships on a two-dimensional surface. Linear perspective depicts how objects appear to a spectator looking in a specific direction from a particular vantage point.
Station point – A fixed point in space representing a single eye of the spectator
Vanishing point – Horizon line – the point on the picture plane at which a set of receding parallel lines appears to converge, or come together as one Horizon line – a horizontal line representing the intersection of the picture plane and a horizontal plane
Vanishing point eye level horizon line station point
Ground line – a horizontal line representing the intersection of the ground plane and the picture plane

The Cone of Vision is the general field of vision The Cone of Vision is the general field of vision. Think of this as the area that you can see. Typically, the Cone of Vision extends 30 degrees on either side of a central axis from the Station Point to the central Vanishing Point. A 60 degree range is considered to be a normal field of vision, and should serve as a guideline when constructing a perspective drawing.

-Orthogonal lines -Transversal lines So now that you have the basic framework for a perspective space, it’s time to start using line to establish forms / objects in that space. In perspective drawing, there are two types of construction lines: -Orthogonal lines -Transversal lines
Orthogonal lines – Transversal lines – -parallel to the ground plane -move back from the picture plane (recede) -appear to meet at a vanishing point on the horizon Transversal lines – -always at right angles to the orthogonal lines -parallel to the picture plane -establish a fixed height or width between two orthogonal lines

When working with one vanishing point, you are working with one-point perspective, also known as central perspective.
