Three-point perspective  

                 Three-point perspective exists when the perspective is a view of a Cartesian scene where the picture plane is not parallel to any of the scene's three axes. Each of the three vanishing points corresponds with one of the three axes of the scene. One-point, two-point, and three point perspectives appear to embody different forms of calculated perspective.

The methods required to generate these perspectives by hand are different. Mathematically, however, all three are identical: The difference is simply in the relative orientation of the rectilinear scene to the viewer.

I did a towered old house with tree and clouds. The tower is connected to vanishing point and trees and clouds are perspective to the point.
