Abstract:
AbstractThe presented study investigates differences in engineering designers' CAD performance when modelling from two types of projections in technical drawings – isometric and orthographic. The results revealed significant differences in the percentage of correctly replicated components' size and shape, indicating better CAD outcomes when generating CAD models from the orthographic projection. In addition, a comparison of duration, as well as the number and type of sketch entities, sketch relations, and CAD features, showed that CAD modelling processes were similar in both conditions.

Abstract:
Abstract. In this paper, we propose the 3D surface reconstruction scheme using multi-view and multi-date Google Earth (GE) satellite images. Multi-view stereo matching (MVS) scheme is one of the methods for reconstructing dense 3D surface based on multi-view images and corresponding camera pose geometry. If many views are input, MVS can estimate the disparity (depth) by matching pixels. However, the common users are not always possible to obtain both multi-view satellite images and the camera geometry (such as Rational Polynomial Camera) in various earth regions. Instead, the GE provides multi-view and multi-date satellite images of earth regions. Therefore, the goal of the proposed method is to perform a 3D surface reconstruction using the GE satellite image. We suppose that the GE satellite image is a pinhole camera model, and the camera pose geometry is estimated using the perspective projection model (PPM) based structure from the motion (SfM) method. Then the 3D surface is reconstructed and fusion using the MVS method. However, the GE satellite image is a transformed pseudo-orthoimage for integration into the raster image. For this reason, the camera pose geometry is inaccurately computed in the SfM process. Thus, the high-rise structures in the reconstructed 3D surface are distorted (distorted hexahedral 3D space). Importantly, the satellite image is a weak PPM and it can express the orthographic projection model. Therefore, we compute 3D homography for transforming between distorted hexahedral space to orthographic cuboid space. Then, the distorted 3D surface is transformed using a projective reconstruction based on 3D homography. The transformed 3D surface has the correct shape in the orthographic projection model. The advantage of the proposed method is that the 3D surface of various earth regions is reconstructed using simply accessible GE satellite images. And the transformed 3D surface is reconstructed into orthographic projection model space, thus the orthoimage can be generated using projection.

Abstract:
The map named Carta Geographica de Projecçaõ Espherica Orthogonal da Nova Lusitania ou America Portugueza e Estado do Brazil from 1798, together with its 1795 (?), 1797 and 1803 versions, is undoubtedly one of the cartographic monuments developed by Portuguese cartography from the late eighteenth century. Its organizer was the geographer, astronomer, and frigate captain Antonio Pires da Silva Pontes Leme, who relied on the work of 34 people, including astronomers, geographers, and engineers, who, although only mentioned in the 1798 version, contributed to the creation of all versions. All of them are similar in appearance, but differ in size, content, details, amount, and distribution of toponyms, which will be the subject of another paper. The greatest similarity, however, concerns the defined map projection. The objective of this paper is to analyse and present the possible hypotheses and conclusions about which map projection was adopted for all versions of Nova Lusitania, through the identification of characteristics that allowed to infer and prove the adopted projection. The applied methodology verified that in the bibliographic search, the information about the map structure is insufficient. An article presented by General Djalma Polli Coelho in October 1950 states that the projection suggested by its title, as orthogonal spherical, appeared to be the Sanson-Flamsteed equal-area projection. However, the expression Carta Geographica de Projecçaõ Espherica Orthogonal allows us to infer also the transverse orthographic projection. Through parameters defined for the two projections, it was possible to establish the comparative elements for a cartographic analysis, which would allow us to conclude and prove the structure adopted for the map, allowing to conclude if the adopted projection for the Nova Lusitania was an azimuthal orthographic equatorial projection, or a Sanson-Flamsteed, sinusoidal projection on the meridian 315°, defined west-east, (counterclockwise), from the El Hierro (Ferro) Island. This meridian is referenced approx. –62°39'46" off the Greenwich meridian.

Abstract:
Objects of more than three dimensions can be used to model geographic phenomena that occur in space, time and scale. For instance, a single 4D object can be used to represent the changes in a 3D object’s shape across time or all its optimal representations at various levels of detail. In this paper, we look at how such higher-dimensional space-time and space-scale objects can be visualised as projections from ℝ4to ℝ3. We present three projections that we believe are particularly intuitive for this purpose: (i) a simple ‘long axis’ projection that puts 3D objects side by side; (ii) the well-known orthographic and perspective projections; and (iii) a projection to a 3-sphere (S3) followed by a stereographic projection to ℝ3, which results in an inwards-outwards fourth axis. Our focus is in using these projections from ℝ4to ℝ3, but they are formulated from ℝnto ℝn−1so as to be easily extensible and to incorporate other non-spatial characteristics. We present a prototype interactive visualiser that applies these projections from 4D to 3D in real-time using the programmable pipeline and compute shaders of the Metal graphics API.

Abstract:
The meaning of term &ldquo
representation&rdquo
has shifted in both relevancy and definition in the discipline of architecture with the introduction of computational design technologies. The assumption of this study is that the selected mode of representation has the power to affect the process of design and even the production of architecture. At the present time, while the discipline is witnessing a change in its tendencies and terminologies, such as from drawing to 3D modeling, from construction to fabrication, and from geometry to topology, it is crucial to look at the &ldquo
conventions&rdquo
of architectural representation that are identified through &ldquo
projections,&rdquo
and particularly the &ldquo
orthographic set&rdquo
. This study aims to challenge the prejudices against the &ldquo
orthographic set&rdquo
that consider it to be an ineffective or inadequate tool for representation in the contemporary practice of architecture following the emergence of &ldquo
digitization&rdquo
. It is the claim of this thesis that the &ldquo
orthographic set&rdquo
is actually a methodology that is still powerful in the visualization of the &ldquo
rational&rdquo
thinking processes of design, and is still a highly pertinent technique in the representation and production of architecture. With the arrival of computational design technologies to the practice of architecture, the &ldquo
visibility&rdquo
of its representations have started to blur
and considering the dialectics between architectural representation and the architectural object, while Modern Architecture can be assessed as the transformation of the orthographic set into a declaration of a stylistic manifesto, in the digital age the question arises of what makes architecture visible, and whether it is possible to come up with a &ldquo
new&rdquo
definition of style.

Abstract:
L'étude des caméras et des images a été un sujet prédominant depuis le début de la vision par ordinateur, l'un des principaux axes étant l'estimation de la pose et la reconstruction 3D. Le but de cette thèse est d'aborder et d'étudier certains problèmes et méthodes spécifiques du pipeline de la structure-from-motion afin d'améliorer la précision, de réaliser de vastes études pour comprendre les avantages et les inconvénients des modèles existants et de créer des outils mis à la disposition du public. Plus spécifiquement, nous concentrons notre attention sur les pairs stéréoscopiques et les triplets d'images et nous explorons certaines des méthodes et modèles capables de fournir une estimation de la pose et une reconstruction 3D de la scène.Tout d'abord, nous abordons la tâche d'estimation de la profondeur pour les pairs stéréoscopiques à l'aide de la correspondance de blocs. Cette approche suppose implicitement que tous les pixels du patch ont la même profondeur, ce qui produit l'artefact commun dénommé "foreground-fattening effect". Afin de trouver un support plus approprié, Yoon et Kweon ont introduit l'utilisation de poids basés sur la similarité des couleurs et la distance spatiale, analogues à ceux utilisés dans le filtre bilatéral. Nous présentons la théorie de cette méthode et l'implémentation que nous avons développée avec quelques améliorations. Nous discutons de quelques variantes de la méthode et analysons ses paramètres et ses performances.Deuxièmement, nous considérons l'ajout d'une troisième vue et étudions le tenseur trifocal, qui décrit les contraintes géométriques reliant les trois vues. Nous explorons les avantages offerts par cet opérateur dans la tâche d'estimation de pose d'un triplet de caméras par opposition au calcul des poses relatives paire par paire en utilisant la matrice fondamentale. De plus, nous présentons une étude et l’implémentation de plusieurs paramétrisations du tenseur. Nous montrons que l'amélioration initiale de la précision du tenseur trifocal n'est pas suffisante pour avoir un impact remarquable sur l'estimation de la pose après ajustement de faisceau et que l'utilisation de la matrice fondamentale avec des triplets d'image reste pertinente.Enfin, nous proposons d'utiliser un modèle de projection différent de celui de la caméra à sténopé pour l'estimation de la pose des caméras en perspective. Nous présentons une méthode basée sur la factorisation matricielle due à Tomasi et Kanade qui repose sur la projection orthographique. Cette méthode peut être utilisée dans des configurations où d'autres méthodes échouent, en particulier lorsque l'on utilise des caméras avec des objectifs à longue distance focale. La performance de notre implémentation de cette méthode est comparée à celle des méthodes basées sur la perspective, nous considérons que l'exactitude obtenue et la robustesse démontré en font un élément à considérer dans toute procédure de la SfM
The study of cameras and images has been a prominent subject since the beginning of computer vision, one of the main focus being the pose estimation and 3D reconstruction. The goal of this thesis is to tackle and study some specific problems and methods of the structure-from-motion pipeline in order to provide improvements in accuracy, broad studies to comprehend the advantages and disadvantages of the state-of-the-art models and useful implementations made available to the public. More specifically, we center our attention to stereo pairs and triplets of images and discuss some of the methods and models able to provide pose estimation and 3D reconstruction of the scene.First, we address the depth estimation task for stereo pairs using block-matching. This approach implicitly assumes that all pixels in the patch have the same depth producing the common artifact known as the ``foreground fattening effect''. In order to find a more appropriate support, Yoon and Kweon introduced the use of weights based on color similarity and spatial distance, analogous to those used in the bilateral filter. We present the theory of this method and the implementation we have developed with some improvements. We discuss some variants of the method and analyze its parameters and performance.Secondly, we consider the addition of a third view and study the trifocal tensor, which describes the geometric constraints linking the three views. We explore the advantages offered by this operator in the pose estimation task of a triplet of cameras as opposed to computing the relative poses pair by pair using the fundamental matrix. In addition, we present a study and implementation of several parameterizations of the tensor. We show that the initial improvement in accuracy of the trifocal tensor is not enough to have a remarkable impact on the pose estimation after bundle adjustment and that using the fundamental matrix with image triplets remains relevant.Finally, we propose using a different projection model than the pinhole camera for the pose estimation of perspective cameras. We present a method based on the matrix factorization due to Tomasi and Kanade that relies on the orthographic projection. This method can be used in configurations where other methods fail, in particular, when using cameras with long focal length lenses. The performance of our implementation of this method is compared to that given by the perspective-based methods, we consider that the accuracy achieved and its robustness make it worth considering in any SfM procedure

Abstract:
The primary focus of this study examines the effectiveness of the CRIOSAT (Computerized Rotational Isometric and Orthographic Spatial) spatial ability treatment on a random sample of middle school students' (n=137) spatial ability as measured by the Purdue Spatial Visualization Test: Rotations Test (PSVT-ROT) (Guay, 1977). The secondary focus of this study investigates the relationships between mathematical achievement, problem solving preferences, and spatial ability. The secondary focus was tested on a subsample (n=41), with the problem solving preferences measured via the Mathematical Processing Instrument (MPI) (Suwarsono, 1982). Findings indicated no significant gains in spatial ability scores after students' use of the CRIOSAT treatment; while some increases in spatial ability took place in males. Significant positive correlation was identified between mathematics achievement and spatial ability; while conversely, a significant negative correlation was found between mathematics achievement and level of visual problem solving used by students.

The learning process of introductory studies, the orthogonal projective system and constituent elements (point, line and plane), used in Geometry for high school students in technical training courses makes it difficult to develop spatial vision and graphic representation. Learning to see allows the student to understand the formation of projections and return to the practice of observation. Three-dimensional visualization produces recognition of the projected image. The development of this learning cannot be restricted to study based only on programmed handouts with forms or feedback solutions.This Design-Based Research developed and implemented a system of security cameras to aid in visualization. This innovation provided for the construction of an educational experience that fosters collaborative learning through interaction with three-dimensional models of the objects to be represented in graphic drawings. The proposal to investigate the practice of graphic representation and strategies for development of this graphic language was carried out with students, aged between 14 and 17 years, in high school at a state technical school. Data collection was done by the researcher in research logs, activities proposed in class and recordings from security cameras positioned to capture the image ?pura. Results underline the importance of creating an educational process applied to technical drawing that develops the act of the careful observation and integration of objects and images with the main aspects of projective drawing. This enables the learning of the concepts of descriptive geometry and facilitates the visualization of the trihedral system and the design of the principal orthographic views (front, top and side) utilizing varied teaching strategies

Abstract:
This dissertation is a study of a remarkable change that came about in the kind of drawings that architects used to present their work between the decades of 1960 and 1990. Drawings in this period, visually rich and compositionally complex, seemed to mark an entirely new sensibility towards their function; their goal seemed to be not so much to clearly depict the forms of a proposed building, but to instead focus on its conceptual aspects. In fact, in several cases, drawings seemed to be treated as graphic projects in their own right, over and above the work they presented. This trend was accompanied by two other developments. Around the same time, there was a sudden increase in theoretical interest in drawings within the architectural community leading to a flurry of published articles, essays and books on the topic. And all this happened to coincide with the time that the Postmodern movement came to dominate architecture. The study aims to understand the relationship between these trends, and to develop a better understanding of the reasons for these changes to have occurred. It does so by, first, developing a theoretical framework to help understand the nature and impact of the changes in drawings. Next, it presents a detailed historical account of these changes. This is followed by an in-depth study of a single architect, James Stirling, to show how the new types of drawings were not simply a means to present ideas, but played a formative role in design as well. Apart from developing a contextualized historical account of an important development in contemporary architectural history, the study also finds that the change in the drawing practice and the theoretical interests were not simply an outcome of Postmodern cultural theory of the period, but were instigated by concerns that arose from within architecture itself. It thus offers a useful case-study on how changes in disciplinary practice are brought about.

Traditional drafting has gradually been replaced by computer-aided drafting due to its convenience. Many drafts can even be obtained from 3D CAD models directly. Students tend to focus on using the computer software for design and drafting, resulting in lacks of training on the draft reading. Therefore, in this study, an orthographic projection learning module was developed to help students to rapidly improve their capability on draft reading and Computer-aided drafting. The orthographic projection learning module was developed in AutoCAD 2012. A plug-in pull-down menu of Orthographic Projection was added with twelve exercises for selection. The exercises contain three projected views and a perspective view of the model. Different colors are used to distinguish the different surfaces. The training process is suggested to be four stages, starting with reading views only to gradually adding views for drafting. Tests were conducted on students without drafting experiences. After preliminary teaching about the basic graphic theory and software tools, the students used the learning module to learn Computer-aided drafting. After the four-stage training, a new problem was tested to evaluate the improvement, together with a questionnaire survey. The results showed that the accuracy and efficiency of drafting can be improved effectively after using this orthographic projection learning module.

Abstract:
Abstract This paper describes an algorithm to generate 3-D solid models of objects from their orthographic projections. This approach is entirely different from the earlier bottom-up approaches. Instead of generating the 3-D vertices, edges and faces sequentially, this approach considers an object to be the boolean combination of a number of elementary objects, which are 2.5D solids. The elementary objects are formed by decomposing a given view into loops and sweeping each loop perpendicular to the direction of projection. This algorithm can handle objects whose projections have curved edge(s) in one view of the orthographic projection. It is believed that proper extension of this algorithm can handle sectional views and multiple views, which has not been addressed in the bottom-up approach.

Abstract:
In discipline and practice, architecture works with conventions of perspective and orthographic projection inherited from the Renaissance. Perspective projections produce illusions that simulate vision, orthographic projections set out measurable dimensions that allow three-dimensional buildings to be con-structed from scaled two-dimensional drawings. These two modes of projection may seem to be at odds with each other, one emphasizing the art of architecture in qualitative illusory effects, the other emphasizing the technology of architecture in quantitative measure. But of course, many of the most com-pelling architectural drawings incorporate both the ‘art’ and ‘technology’ of architecture. This type of hybrid drawing, that is partly illusionistic and partly measurable,1 is particularly useful in imagining what a building could be without losing track of the measurements of the physical world in which it must exist.

Abstract:
In this paper is proposed a method to reconstruct a solid from given two or three orthographic views along with any number of primary auxiliary views based on the combination of wireframe and volumetric approaches. None of the existing works in automatic reconstruction of solids from two dimensional orthographic views have addressed auxiliary views in detail. Polyhedral approximation of cylindrical, conical, toroidal and spherical surfaces is considered. The algorithm presented, entails the construction of the basic wire-frame from given standard views using the wire-frame approach. The projections in the auxiliary views on the basic orthographic views are swept along the projection lines to form the primitives. These primitives are glued to the basic wire-frame to construct the final solid. Numerous examples are presented in this paper to demonstrate the versatility of the proposed method which can handle partial standard and auxiliary views as well.

Abstract:
Abstract The ability of an engineer to visualize and reason about geometric aspects of physical objects and processes is crucial in the success of engineering activities. The paper presents the development of a prototype visual reasoning system which aims at increasing engineering students’ visual reasoning capabilities. Specifically we take the missing view problem which requires students to construct any valid solid and a corresponding missing orthographic view when they are given two orthographic views. Sweeping operations, which are the reverse procedure of orthographic projection, are used to solve missing view problems by forming the boundary faces of a solid from the loops of orthographic views. This geometric operation forms a primary user interface of the system in visually reasoning about the construction of 3-D solid given the constraints by two orthographic views.
