Early Perspective Painting and the Beginnings of Projective Geometry
The cone of visual rays has its vertex at the eye. A perspective painting is a section of this cone by a plane.
But isnt the perspective construction something to do with vanishing points?? That seems like a different idea!

Draw a square in perspective:
Last construction line
Why is this construction correct? DE:BC = AE:AC = HE:GC But BC = GC, so DE = HE
A degraded octagon
A hexagonal well
The Baptism of Chris
The flagellation of Christ
Perspective in the Flagellation of Christ
A misuse of perspective?
Two pencils of lines These are EQUIVALENT in projective geometry: one can be transformed into the other.
Art and optics A recent symposium considered the possibility that Renaissance perspective effects did not require geometrical construction after all! The suggestion is that artists used lenses and mirrors to project images, and trace them.
