How to draw a virtual cubical perspective box

Publication . Araújo, António; Lucas, Olivero

In this workshop we will learn how to draw a cubical perspective by hand and how to visualize the resulting drawing as a VR panorama, creating a kind of virtual perspective box. We will do this by viewing cubical perspective as a special case of spherical perspective and considering how spherical geodesics project on the cube.

Drawn onto a skybox: an invitation to collaborative immersive drawing using the spheri platform

Publication . Araújo, António; Olivero, Lucas Fabian

We describe an installation that invites the audience to collaborate on the performance of immersive drawings that will be visualized on-the-fly using the custom hardware-software platform Spheri. These drawings are made on a flat surface using traditional physical materials and following a modular tracing process that helps the user conform to the rules of cubical spherical perspective. Concurrently with the drawing performance, the Spheri platform captures the drawing and converts it into an immersive VR visualization on-the-fly, while tracking the drawing motion and choosing the camera viewpoint accordingly. The installation explores the new media of immersive handmade perspectives as well as new forms of intuitive and performative visualization. Countering the expectations of digital media as instruments for efficiency and ease of production, it aims instead at leading the user into slow and pondered geometrical thinking through handmade immersive drawing.

Enhancing the teaching of spherical perspective with spheri

Publication . Olivero, Lucas Fabian; Araújo, António

Spherical perspectives and the practice of immersive drawing are going through a period of rapid development along with a concurrent growth of interest in their applications to various fields. The teaching of new practitioners must often be done in short workshops lateral to established curricula, which is a challenge due to the complexity of the subject. We present a digital tool for performative immersive drawing that can be instrumental in enabling a quick and informative transmission of the principles of immersive drawing to a student audience.

A novel shortcut to cubical perspective drawing

Publication . Olivero, Lucas Fabian; Araújo, António; Rossi, Adriana

The article introduces a novel construction that simplifies the drawing of cubical perspectives. A recent work described a method for drawing cubical perspectives which classifies lines into several types and renders each type systematically. Some of these types require an auxiliary external construction, hindering the drawing process. This research proposes a novel method that shortcuts this step with an internal construction. This method both accelerates and simplifies the studio process, reduces systematic errors, and makes freehand sketching more viable and precise. Next, the shortcut is applied through the case of the Solimene factory (Italy), an organic architecture that highlights both the issues inherent to cubical representation and the advantages of the proposed shortcut.
