Summary
[edit]| Description |
English: y=x2 & y=x3 projected on RP2 mapped onto a sphere. Is basically a ray traced version of File:Parabola_in_projective_space.svg which superseded en:File:Parabola_in_projective_space.png by being an SVG, and by correctly including both parts of the mapping of y=x2. I used two of Friedrich A. Lohmüller's files at http://www.f-lohmueller.de/pov_tut/a_geo/a_geo__e.htm as a template and an include, in order to match the following illustrations by Jean-Christophe BENOIST: |
