title Deconstructing the Constructivist Drawings of Iakov Chernikhov
source From Research to Practice [ACADIA Conference Proceedings] Big Sky (Montana - USA) 4-6 October 1990, pp. 61-77
summary The three-dimensional nature of Chernikhov's Constructivist architecture can be analyzed by a method of reverse perspective deconstruction. After a review and classification of the drawings in Chernikhov's book, 101 Architectural Fantasies, to determine which classes are suitable for deconstruction, the method of perspective deconstruction together with the underlying assumptions is presented and applied to three drawings. Conclusions concerning the forms comprising the architecture depicted in Chernikhov's images and the possibility of representing this Constructivist architecture by shape grammars are discussed.

title A Photogrammetry and Perception Study of Chernikhov Fantasy No. 32 and 38
source CAADRIA 2000 [Proceedings of the Fifth Conference on Computer Aided Architectural Design Research in Asia / ISBN 981-04-2491-4] Singapore 18-19 May 2000, pp. 461-470
summary This research investigated the object composition in Chernikhov's 101 Architectural Fantasies through computer-aided visualization, for the purpose of interpreting the relationships between architectural components. In contrast to traditional simulation analysis, this research applied photogrammetry to investigate the orthogonal and parallel ambiguity of 3D objects in 2D drawings by calculating the position of matching geometries. This test took Fantasy no. 38 and 32 as examples to confirm their spatial relationship. 60 architectural students were asked to conduct 3 tests. The algorithmic approach (photogrammetry calculation) was referenced by a cognitive approach (the perception survey) as a comparison base. Photogrammetry test proved that the relation between objects was usually oriented by personal spatial experiences that did control the deduction process of an observer. Perception survey showed that orthogonal assumption existed in the interpretation process of an object's position. It turned out that a testee would still consider two linear objects intersected in orthogonal angle within a tolerance of 15 degree or parallel position between 4 and -16 degree. The finding showed that the interpretation of paper architecture drawings not only was given by the author, but tended to be re-interpreted by an observer. The interpretation process, just like modeling and rendering process, should be a two-way process that facilitates a study oriented either from 2D images or 3D models.
