Geometric Space

Teaching drawing in architectural education raises questions regarding the representation of spatial experiences: to what extent can sensory experiences of space be intensified through observing and drawing and, perhaps equally important, what those drawings would look like? In the context of their drawing classes, the authors started to inquire the discrepancy between conceiving and perceiving space, and the aptitude of representing spatial concepts upon a two dimensional surface. Through observation and translating observation into drawings, students discover that conventionalised ways of drawing, such as linear perspective, only reveal part of the story. While linear perspective remains the dominant way of representing space, obviously visible in photography, film, 3D-imaging and architectural impressions, the authors started looking for ways of drawing which inquire possibilities of expressing spatial experiences. Drawing as an activity which is able to enhance spatial understanding, rather than as a tool to communicate virtual spaces. Next to drawing as a ‘skill’, which can be learnt, the drawing classes started to inquire non-visual aspects of space by analysing attributes of spatiality, which are difficult to convey through two dimensional drawings. Starting from a contextualisation of spatial drawing within architectural practice, the article examines the discrepancy between geometric space and lived space, in order to reveal the dubious role of linear perspective within (architectural) culture and history. After a brief return to how we imagined and represented space in our childhood, the article presents a series of practice based examples. Drawing on the authors’ teaching practice, it illustrates possibilities to expand our visual language by exploring space and spatiality through observing and drawing.

Microscope is one of the tools used in practicums with high intensity. The use of a microscope adjusts to the object to be observed in order to obtain optimal micrographic results. Stereo microscopes are used to observe three-dimensional objects. Upright microscopes are used to observe two-dimensional objects. This study aims to combine the two advantages of stereo microscopy that can produce three-dimensional micrography with the advantages of an upright microscope that has a high total magnification. The method used in this study is an experimental method by adding an optical fiber illuminator in the use of an upright microscope and then applying it in various observations. The conclusion of this research is the addition of an optical fiber illuminator in observations using an upright microscope can replace the function of a stereo microscope; can produce three-dimensional effects and increase magnification in Daphnia magna micrographic observations.

Constellation shaping has been widely used in optical communication systems. We review recent advances in two-dimensional constellation shaping technologies for fiber-optic communications. The system architectures that are discussed include probabilistic shaping, geometric shaping, and hybrid probabilistic-geometric shaping solutions. The performances of the three shaping schemes are also evaluated for Gaussian-noise-limited channels.
