Abstract:

Supported by the Higher Education Restructuring Fund allocated to ELTE by the Hungarian Government. Themes of the semester:  Weeks 1–2: Concepts and theoretic base of 3D modeling. Types and the “scale” of 3D models. Data and objects in the model. Types of different modeling applications, and the usage of 3D models in the Earth sciences.  Weeks 3–4: Hierarchical data management. Data management systems of the 3D model and their functionalities. The source and the management of primary data. Converting raster into vector and further into numerical data or converting raster directly into numerical data. The structure of GIS databases.  Weeks 5–6: The 2D GIS base of the 3D model. GIS topology types. Connection between the subsystems. Data mining, data classification and data analysis. 11  Weeks 7–9: The modeling procedure. Classification of 3D modeling methods. Comparison of the regular and irregular data-model. Simple and complicated irregular models. The concept of tessellation.  Weeks 10–11: Simple and complicated regular models. Processing and storing grid data. Calculation of grid point values. The concept of scalar-space and vector-space. The medium and the requirements of the visualization. The conceptual 3D model. Models in the virtual space. Tools for visualization and querying.  Week 12-13: Own work, practice, consulting.
