Methods for Automated Creation and Efficient Visualisation of Large-Scale Terrains based on Real Height-Map Data

Kühnert, Kurt 15 December 2022 (has links)
Real-time rendering of large-scale terrains is a difficult problem and remains an active field of research. The massive scale of these landscapes, where the ratio between the size of the terrain and its resolution is spanning multiple orders of magnitude, requires an efficient level of detail strategy. It is crucial that the geometry, as well as the terrain data, are represented seamlessly at varying distances while maintaining a constant visual quality. This thesis investigates common techniques and previous solutions to problems associated with the rendering of height field terrains and discusses their benefits and drawbacks. Subsequently, two solutions to the stated problems are presented, which build and expand upon the state-of-the-art rendering methods. A seamless and efficient mesh representation is achieved by the novel Uniform Distance-Dependent Level of Detail (UDLOD) triangulation method. This fully GPU-based algorithm subdivides a quadtree covering the terrain into small tiles, which can be culled in parallel, and are morphed seamlessly in the vertex shader, resulting in a densely and temporally consistent triangulated mesh. The proposed Chunked Clipmap combines the strengths of both quadtrees and clipmaps to enable efficient out-of-core paging of terrain data. This data structure allows for constant time view-dependent access, graceful degradation if data is unavailable, and supports trilinear and anisotropic filtering. Together these, otherwise independent, techniques enable the rendering of large-scale real-world terrains, which is demonstrated on a dataset encompassing the entire Free State of Saxony at a resolution of one meter, in real-time.

What to teach or how to teach? : A survey on the consequences a less detail-controlled curriculum has on English teachers´ choice of English-language literature

Andrijevic, Valentin January 2023 (has links)
This essay aims to examine which consequences a less-detail controlled curriculum has on English teachers’ choice of English-language literature. With support from the literature review, this essay argues that an unofficial, tacit school canon of English-language literature mainly composed of ten literary works seems to have been established in Swedish upper-secondary schools, despite the Swedish National Curriculum not naming specific literary works educators in Sweden are required to use in their teaching. Thus, this essay answers the following questions: 1) Which English-language literature do English teachers in Sweden use in their teaching? 2) Does a less-detail controlled curriculum contribute to English teachers in Sweden being more inclusive in their choice of literature in teaching? The results support the hypothesis; that despite the ten literary works found in the unofficial, tacit school canon might be vulnerable to the same criticism aimed at the “Western literary canon” and a “prescribed” curriculum. Yet, no evidence was found which would illustrate that a less detail-controlled curriculum does not contribute to English teachers in Sweden being more inclusive in their choice of literature in teaching since the inclusive classroom is not only a matter of what is being taught but also of how it is being taught. Additionally, the study shows that there are countries in the Western world that name literary works as a teaching requirement for educators that “silently” marginalize and privilege some voices. Despite educators not being able to influence what is being taught, educators have developed strategies and methods (critical literacy/pedagogy, and intersectionality) on how these literary works are taught to learners with the aim to make room for a spectrum of voices when being required to teach from a “prescribed” curriculum.

Klimatanpassningsarbetets påverkan på framtidens byggnader : En studie om hur svenska kommuners klimatanpassningskrav påverkar exploatörer vid nyproduktion

MANOUCHEHR, ARMIN, Kull, Felix January 2020 (has links)
Sweden is adapted to a certain type of climate. The conditions that the climateprovides determine how buildings are constructed and designed. In 2018 the Swedishgovernment introduced a national climate adaption strategy to adapt Sweden toclimate change. As a result of this the municipalities in Sweden need to increase theirdemands on developers in new construction work. The climate adaptationrequirements can, among other things, lead to increased costs.The purpose of this thesis and the research questions answered are to investigatewhat climate adaptation requirements Swedish municipalities impose in the detailedplanning process and how they affect developers' investments in new constructionwork.An interview-based, qualitative method with an abductive approach have been used.Four municipalities, three developers and two other actors were interviewed. Theresults obtained were that the requirements set were based on the conditions of thesite and that the property should be suitable for development. The most commonproblems the municipalities said they had are rainfall, flooding, and sea level rise.Hence, the stormwater issue becomes important and demands are placed ondevelopers to follow the municipality's stormwater strategies.Further, there are also shared opinions about what type of requirements themunicipality may impose, which has led to ambiguities regarding procedures, divisionof responsibilities and funding. The requirements that may be imposed can also havean impact on revenue and costs that form the basis of the developers' computation.Furthermore, this is one of several factors that influence their investmentassessments.The climate adaptation work is at an early stage and therefore there is lack ofexperience which makes the work more difficult. Over time, municipalities anddevelopers will gain more knowledge about climate adaptation. This will eventuallymake the climate work easier in ways that municipalities, developers, and other actorswill get a better picture of the future climate conditions and the approaches that shouldbe used.

Memory [Architecture] Film: Four Cinematic Events in the City

Egues, Magdalena 08 April 2008 (has links)
Cities involve several systems that work together as a network of urban relationships. These systems are in balance, and they work as a whole that articulates urban life. But what makes a city memorable and special are its events: those magical situations where the uniformity of the experience stops and something unique arise. Those are the moments where our memory is deeply engraved by a particular situation that will come back in our dreams and imaginative processes as an agent image. Four urban events — a space for film edition and writing, an urban stage, a footage archive and park, and a projection space- whose locations have been determined by a Cartesian game dictated by the Plan of Washington DC; and one common discipline, Film, will be the main focus of this research and a way of understanding the relations among Memory and its spaces, Architecture and Film in the City. Each event will respond to the particularities of its context by understanding first the sites and their relation with the city. These sites will be located in the four quadrants of Washington DC- NE, SE, SW and NW- and they will be consider as different communities that, by keeping their own idiosyncrasy, create one city. The question of urban scale as well as the concept of detail as part of an architectural cosmology will be present throughout the process of the thesis by the alternation of micro and macro analysis of each stage of the research. The question of scale will be present as well when comparing the four projects with their differences in shape and size. Characterization and monstrosity as architectural concepts will be incorporated into the project too, by understanding the role of Architecture in the city and what it wants to show or "monstrare" to its inhabitants. / Master of Architecture

Image Approximation using Triangulation

Trisiripisal, Phichet 11 July 2003 (has links)
An image is a set of quantized intensity values that are sampled at a finite set of sample points on a two-dimensional plane. Images are crucial to many application areas, such as computer graphics and pattern recognition, because they discretely represent the information that the human eyes interpret. This thesis considers the use of triangular meshes for approximating intensity images. With the help of the wavelet-based analysis, triangular meshes can be efficiently constructed to approximate the image data. In this thesis, this study will focus on local image enhancement and mesh simplification operations, which try to minimize the total error of the reconstructed image as well as the number of triangles used to represent the image. The study will also present an optimal procedure for selecting triangle types used to represent the intensity image. Besides its applications to image and video compression, this triangular representation is potentially very useful for data storage and retrieval, and for processing such as image segmentation and object recognition. / Master of Science
