How to Construct a Projective Transformation Using Perspectivities

How to construct a projective transformation using perspectivities — following the classical approach presented in Modern Geometries by James R. Smart. In this video, we develop a projectivity through geometric construction: • First, we project three distinct points on one line onto three distinct points on a second line using two perspectivities. • Next, we determine the image of an arbitrary point under the projectivity established. • Finally, we construct a projectivity on the same line by mapping three distinct points to three distinct points using three perspectivities.
