ABSTRACT
In this workshop we will learn – in practice! – how to draw a spherical perspective.
Spherical perspectives are drawings made with pencil on a flat paper, with nothing but your eyes and hands. They can be digitized and visualized as Virtual Reality panoramas.
Spherical perspective relates to 360-degree photography as classical perspective relates to ordinary photography. They make a creative connection between traditional handmade drawing practice and the most sophisticated digital technology, using computers to expand rather than replace the act of drawing.
The activities include, first, a theoretical session about how to draw a certain environment – real or imaginary – using spherical perspectives, and second, a practical sketching session. The drawing session will be enhanced by the use of a digital artifact that enables real time VR visualization of the drawn environment, so that you can peek inside the world that is being created as it is being drawn.
Proficiency in drawing is not required to enjoy this workshop.

ABOUT THE AUTHORS
A. B. Araújo is a mathematician and artist. He researches the theory and practice of spherical perspectives. He aims at technology and theory that stimulate rather than replace handmade drawing. He lectures at Univ. Aberta, Portugal, and coordinates Aberta’s pole of the Research Centre for Arts and Communication (CIAC). His homepage is http://www.univ-ab.pt/~aaraujo/
L. F. Olivero got a PhD in Environment, Design and Innovation in March 2021 with the thesis “Hybrid Immersive Models from Cubical Perspective Drawings”. Currently, he is being funded by FCT for a second PhD in Digital Media Art in a joint program between Universidade Aberta and Universidade do Algarve, Portugal. His homepage is https://www.lufo.art
C. Masiero Sgrinzatto is an illustrator and designer based in Venezia, Italy. She has been creating 360° contents for more than 15 years, specializing in hand-drawn spherical illustrations. She designs and develops visual communication projects for many clients worldwide, swinging between the analogue and digital worlds. Her homepage is https://www.chiaramasierosgrinzatto.com
