Alvar Aalto's Associative Geometries
Alvar Aalto Researchers’ Network Seminar – Why Aalto? 9-10 June 2017, Jyväskylä, Finland Alvar Aalto’s associative geometries Holger Hoffmann Prof. Dipl.-Ing., Architekt BDA Fay Jones School of Architecture and Design Why Aalto?, 3rd Alvar Aalto Researchers Network Seminar, Jyväskylä 2017 Prof. Holger Hoffmann, Bergische Universität Wuppertal, April 30th, 2017 Paper Proposal ALVAR AALTO‘S ASSOCIATIVE GEOMETRIES This paper, written from a practitioner’s point of view, aims at describing Alvar Aalto’s use of associative geometries as an inspiration for contemporary computational design techniques and his potential influence on a place-specific version of today’s digital modernism. In architecture the introduction of digital design and communication techniques during the 1990s has established a global discourse on complexity and the relation between the universal and the specific. And however the great potential of computer technology lies in the differentiation and specification of architectural solutions, ‘place’ and especially ‘place-form’ has not been of greatest interest since. Therefore I will try to build a narrative that describes the possibilities of Aalto’s “elastic standardization” as a method of well-structured differentiation in relation to historical and contemporary methods of constructing complexity. I will then use a brief geometrical analysis of Aalto’s “Neue Vahr”-building to hint at a potential relation of his work to the concept of ‘difference and repetition’ that is one of the cornerstones of contemporary ‘parametric design’. With the help of two projects (one academic, one professional) I will furthermore try to show the capability of such an approach to open the merely generic formal vocabulary of so-called “parametricism” to contextual or regional necessities in a ‘beyond-digital’ way. -

Dabrowski 1 , Cezary Specht 1,* , Mariusz Specht 2 and Artur Makar 3 1 Department of Geodesy and Oceanography, Gdynia Maritime University, 81-347 Gdynia, Poland; [email protected] 2 Department of Transport and Logistics, Gdynia Maritime University, 81-225 Gdynia, Poland; [email protected] 3 Department of Navigation and Hydrography, Polish Naval Academy, 81-127 Gdynia, Poland; [email protected] * Correspondence: [email protected] Abstract: The theory of cartographic projections is a tool which can present the convex surface of the Earth on the plane. Of the many types of maps, thematic maps perform an important function due to the wide possibilities of adapting their content to current needs. The limitation of classic maps is their two-dimensional nature. In the era of rapidly growing methods of mass acquisition of spatial data, the use of flat images is often not enough to reveal the level of complexity of certain objects. In this case, it is necessary to use visualization in three-dimensional space. The motivation to conduct the study was the use of cartographic projections methods, spatial transformations, and the possibilities offered by thematic maps to create thematic three-dimensional map imaging (T3DMI). The authors presented a practical verification of the adopted methodology to create a T3DMI visualization of Citation: Dabrowski, P.S.; Specht, C.; Specht, M.; Makar, A. the marina of the National Sailing Centre of the Gda´nskUniversity of Physical Education and Sport Three-Dimensional Thematic Map (Poland). -
Members | Diagnostic Imaging Tests
Types of Diagnostic Imaging Tests There are several types of diagnostic imaging tests. Each type is used based on what the provider is looking for. Radiography: A quick, painless test that takes a picture of the inside of your body. These tests are also known as X-rays and mammograms. This test uses low doses of radiation. Fluoroscopy: Uses many X-ray images that are shown on a screen. It is like an X-ray “movie.” To make images clear, providers use a contrast agent (dye) that is put into your body. These tests can result in high doses of radiation. This often happens during procedures that take a long time (such as placing stents or other devices inside your body). Tests include: Barium X-rays and enemas Cardiac catheterization Upper GI endoscopy Angiogram Magnetic Resonance Imaging (MRI) and Magnetic Resonance Angiography (MRA): Use magnets and radio waves to create pictures of your body. An MRA is a type of MRI that looks at blood vessels. Neither an MRI nor an MRA uses radiation, so there is no exposure. Ultrasound: Uses sound waves to make pictures of the inside of your body. This test does not use radiation, so there is no exposure. Computed Tomography (CT) Scan: Uses a detector that moves around your body and records many X- ray images. A computer then builds pictures or “slices” of organs and tissues. A CT scan uses more radiation than other imaging tests. A CT scan is often used to answer, “What does it look like?” Nuclear Medicine Imaging: Uses a radioactive tracer to produce pictures of your body. -

189_09 aju 03 Bryon 8/1/10 07:25 Página 31 Measuring the qualities of Choisy’s oblique and axonometric projections Hilary Bryon Auguste Choisy is renowned for his «axonometric» representations, particularly those illustrating his Histoire de l’architecture (1899). Yet, «axonometric» is a misnomer if uniformly applied to describe Choisy’s pictorial parallel projections. The nomenclature of parallel projection is often ambiguous and confusing. Yet, the actual history of parallel projection reveals a drawing system delineated by oblique and axonometric projections which relate to inherent spatial differences. By clarifying the intrinsic demarcations between these two forms of parallel pro- jection, one can discern that Choisy not only used the two spatial classes of pictor- ial parallel projection, the oblique and the orthographic axonometric, but in fact manipulated their inherent differences to communicate his theory of architecture. Parallel projection is a form of pictorial representation in which the projectors are parallel. Unlike perspective projection, in which the projectors meet at a fixed point in space, parallel projectors are said to meet at infinity. Oblique and axonometric projections are differentiated by the directions of their parallel pro- jectors. Oblique projection is delineated by projectors oblique to the plane of pro- jection, whereas the orthographic axonometric projection is defined by projectors perpendicular to the plane of projection. Axonometric projection is differentiated relative to its angles of rotation to the picture plane. When all three axes are ro- tated so that each is equally inclined to the plane of projection, the axonometric projection is isometric; all three axes are foreshortened and scaled equally. -
Smart Sketch System for 3D Reconstruction Based Modeling

Informática, IST, Av.Rovisco Pais 1049-001 Lisboa, Portugal [email protected] Abstract. Current user interfaces of CAD systems are still not suited to the ini- tial stages of product development, where freehand drawings are used by engi- neers and designers to express their visual thinking. In order to exploit these sketching skills, we present a sketch based modeling system, which provides a reduced instruction set calligraphic interface to create orthogonal polyhedra, and an extension of them we named quasi-normalons. Our system allows users to draw lines on free-hand axonometric-like drawings, which are automatically tidied and beautified. These line drawings are then converted into a three- dimensional model in real time because we implemented a fast reconstruction process, suited for quasi-normalon objects and so-called axonometric inflation method, providing in this way an innovative integrated 2D sketching and 3D view visualization work environment. 1 Introduction User interfaces of most CAD applications are based on the WIMP (Windows, Icons, Menus and Pointing) paradigm, that is not enough flexible to support sketching activi- ties in the conceptual design phase. Recently, work on sketch-based modeling has looked at a paradigm shift to change the way geometric modeling applications are built, in order to focus on user-centric systems rather than systems that are organized around the details of geometry representation.
