Scientific reconstruction of the fossil marine amniots
Cettl, Karel ; Mazuch, Martin (advisor) ; Ekrt, Boris (referee)
To create a good scientific reconstruction is important artistic skills and knowledge of history painting of prehistoric animals, and also knowlages in the anatomy, zoology, palaeontology, palaeoecology and also biomechanics. Reconstruction It stands on the borderline between art and science. Our view on the fossil marine Amniotes change over time with advancing skeletal findings, and also changed a scientific reconstruction. Although the actual outputs, such as reconstruction and in particular 3D models can explain a number of new or unexplained informations about this group. A reconstruction expert can not only beautify their actions, but also enthance scientific knowledge, or even to outline a new direction for further research. Keywords: Scientific reconstruction, fossil marine amniotes, adaptation, anatomy, evolution, palaeoecology, biomechanice, 3D models, trends.

Model visualization in virtual reality
Lukačovič, Samuel ; Lacko, Branislav (referee) ; Hůlka, Tomáš (advisor)
This thesis is dedicated to a term called virtual reality, its history, applications and possible technological adaptations. Subsequently the focus is going to shift towards a type of software called game engine. The function, historical development and various kinds of game engines are going to be closely described. Practical part of the thesis is going to be focused on making of training simulation in virtual reality. During development the unique features of the chosen game engine, thanks to which this game engine is suitable for creating such applications, are going to be used.

Searching for Similar 3D Models
Sálus, Ondřej ; Beran, Vítězslav (referee) ; Španěl, Michal (advisor)
Goal of this paper is development of aplication for comparing of 3D models. It deals with extraction od descriptors suitable for comparing of 3D models and enables to find models similar to users query. For extraction of descriptors application uses Reeb graph method. This paper also describes usage of libraries that implements Reeb graph method and some experiments with speed and quality over pre prepared models database.

The method of conservation, preservation, and restoration of subjects of cultural heritage on the ceramic basis (fired/unfired clay)
Štefcová, P. ; Kadeřábková, J. ; Polák, L. ; Valach, Jaroslav ; Vavřík, Daniel
The ceramic (decorative or utility) accompanies humanity from prehistoric times to the present days. Therefore, ceramic play important role in collections in all institutions. Due to the nature of the material are those items extremely sensitive to mechanical damage. The submitted method explains the damage mechanism or destruction of the items of cultural heritage. The method also summarizes recommendations for designing the optimal condition of depositing, exhibiting, conservation/restoration, and the manipulation with such sensitive material. Including a description of several methods useful to make quality documentation and replication of cultural heritage items (3D models). \n

Interactive Example-based Stylization of Architectural Models
Hauptfleisch, Filip ; Sýkora, Daniel (advisor) ; Pelikán, Josef (referee)
One of the ways in which architects communicate their designs is through hand-made architectural sketches. Often it would be beneficial to have a sketch drawn from several angles, but producing many sketches is time- consuming for the architect. Another interesting visualization tool could be an interactive smooth rotation around a stylized scene, which would be impossible to do by hand. Style transfer is an area from non-photorealistic rendering. It tries to solve the problem of transferring a style from an image to another one. This work introduces the current state of style transfer and compares several methods of transferring an architectural sketch style from one view of a 3D scene to another view of the same scene. The StyLit algorithm is then expanded to run the style transfer for multiple viewpoints at the same time while maintaining spatially coherent results. Finally, a method to run an interactive smooth movement around the stylized scene is introduced. 1

Model visualization in virtual reality
Cmajdálka, Ondřej ; Dobrovský, Ladislav (referee) ; Hůlka, Tomáš (advisor)
This thesis deals with phenomenon called virtual reality, its historical development and nowadays used technologies. The next part is dedicated to game engines, their history and structure. In practical part a proposal and development of virtual reality environment is described. The proposed environment demonstrates selected features of the game engine that make it a suitable tool for developing virtual reality environments.

Watermarking 3D Models
Stehlík, Václav ; Beran, Vítězslav (referee) ; Španěl, Michal (advisor)
This bachelor's thesis is dedicated to embedding and extraction of watermarks to/from 3D models represented by polygonal mesh. The goal is to choose a suitable method for watermark embedding and extraction to/from a 3D model for the purpose of implementing a tool of such capabilities. The resulting solution uses methods proposed in article A Novel Blind Robust Digital Watermarking on 3D Meshes . Used methods create two watermarks. 'OTC' watermark that changes vertices of the model and 'Zero' watermark that does not change the model at all. These watermarks provide robustness against attacks and modification such as translation, scaling, rotation, simplification, random noise, remeshing and vertex reordering. Used methods also preserve imperceivability of watermark thanks to minimal changes of the model. Methods are blind and do not require original model. The tool is implemented in a form of simple web application which allows user to embed and extract watermark to/from files in stl format. This work includes testing and evaluation of success and usability of the tool against various attacks on chosen test set of models.

Creation and Demonstration of Assets for VR Application
Zouhar, Marek ; Tóth, Michal (referee) ; Milet, Tomáš (advisor)
This thesis deals with the concept of virtual reality, its history, present-day possibilities and available devices and technologies for virtual reality and ways of creating assets such as models, textures and animations for virtual reality applications. The practical part of this work deals with design and creation of three-dimensional models, textures, animations and environment for use in interactive application in virtual reality and also with design and creation of such application to demonstrate their use.
