projective geometry

study of geometric properties that are not changed by projection

Projective geometry is a non-metrical form of geometry. First developed by Desargues in the 17th century, it did not achieve prominence as a field of mathematics until the early 19th century through the work of Poncelet and others. Projective geometry originated from the principles of perspective art.
