The Elegance of Perspective: Exploring Luis Santaló’s Geometría Proyectiva
To handle "points at infinity" without the mess of limits, projective geometry uses homogeneous coordinates. Santaló’s texts provide the algebraic framework necessary to transition from the Euclidean planes we learn in high school to the projective spaces used in modern computer vision and graphics. 3. Conics and Quadrics
Perhaps the most beautiful section of the book deals with conics as projective curves. Santaló demonstrates that an ellipse, parabola, and hyperbola are projectively equivalent—only their relation to the "line at infinity" differs. He then introduces polarity theory, mapping points to lines with respect to a conic.
