Stereoscopic Drawing Experiments Attempts at Unpicking Baroque Spatiality

Abstract

The essay juxtaposes current strands of research in my PhD that focuses on the one hand on historical stereoscopic devices, their entanglement with vision and descriptive geometry and on the other on the development of my own drawing experiments, that study spatial experience and imagination in respect to projection drawing. Depth perception plays an important role in this, as it makes a large part of spatial experience, while its specifics being often overlooked. The screen-based proceedings in architecture profession and in general progressively focus on communicating and interacting through the screen. What falls into the background is a deepened understanding what distinguishes the experience of the monocular world to the binocular one as the three-dimensional imagination steps into a shadow, and along with it, knowledge on the specificities of spatial depth experience. Looking into the historic academic discourse around depth perception and how the experience of stereoscopic images contributed to apprehend vision, highlights the richness and complexities, that it adds to our visual world. While it might also shed light on what has come amiss in an image and screen-focused world, the drawing experiments bring to live and relink spatial perception to the tools of the profession.
