CENTRAL PROJECTION

π : (X,Y,Z) ↦ (x,y)

One coordinate
did not survive.

Depth entered
as denominator,

then left.

π⁻¹(p) = { λ(x,y,f) | λ > 0 }

Not a point.

A ray.

roof?

window?

white plane,

briefly.

The same image point
admits near matter
and farther matter
without preferring either.

Agreement in (x,y)
proves only
alignment.

Given p,
recover λ.

Or try to.

Extend instead—

past the first green claim,
past the second,

until architecture begins
to take shape
under occlusion,

or occlusion
begins to take the shape
of architecture.
