I'm a mathematician and visual artist, teaching and researching at Universidade Aberta (UAb), in Portugal. My research focuses on anamorphosis and curvilinear perspectives and I have published methods for solving two of these perspectives (equirectangular and azimuthal equidistant) by ruler and compass, without using computers (my latest paper is at https://www.tandfonline.com/doi/full/10.1080/17513472.2018.1469378) I teach these methods to traditional artists and architects so as to expand their possibilities of representation, allowing them to easily calculate and draw all vanishing points of an immersive perspective, almost as easily as in classical perspective. In particular I have taught these methods to the urban sketching community, of which I am part (see some of my drawings at http://urbansketchers-portugal.blogspot.com/search/label/Ant%C3%B3nio%20Ara%C3%BAjo). I also teach these methods to digital artists at UAb's Ph.D. program in digital media art - in this way I hope to give them a deeper understanding of the geometry behind VR/MR technologies, and to inspire them to tinker with their software and/or establish a better communication with developers.
