This project deals with the design and implementation of the extensible programmable environment intended for the creation of various 3D simulations, specifically targeted for testing of the algorithms and creation of applications from the field of computer vision and robotics. Environment VISIMBOX was implemented in c# programming language and uses OpenGL as back-end for hardware accelerated rendering.

The main aim of the thesis is loading of 3D models in different file formats and its displaying, creating of slices from 3D models and vice versa making 3D models from slices, quantify inaccuracy of anti-aliasing and other formatting and investigate similarity of original and edited models. Everything in Java programming language and its extensions for 3D object tasks. Thesis builds on earlier project „3D shape from MRI“.

This work focuses on latest technologies in the augmented reality field and their usage in combination with location based services. This combination enables the use of augmented reality in a virtual guide through an environment. The theoretical part introduces and compares various available technologies, that can be used for creation of such application. In the practical part, an example application is designed and implemented, along with an example scenario. The application is usable in a real-world environment and demonstrates the capabilities of chosen technologies. A possibility of the application's further development is discussed in the work's conclusion, along with it's various aspects, such as user experience, technical outcomes and it's possibility of release.

Šiame magistro darbe nagrinėjamas M3G standartas, skirtas 3D grafikai mobiliuose telefonuose, tiriamos 3D modelių eksportavimo į M3G formatą galimybės bei M3G standarto suderinamumas. Apžvelgiamos 3D modeliavimo bei eksportavimo priemonės bei pasirinkta modeliavimo priemonė Blender, įgalinanti pasiekti 3D modelio duomenis naudojant Python skriptus. Sukurta eksportavimo iš Blender modeliavimo priemonės į M3G formatą schema. Schema realizuojama suprogramavus eksportavimo priemonę vartojant Python bei Java programavimo kalbas. Eksportavimo priemonė veikia kaip papildomas įrankis Blender modeliavimo priemonėje ir gali būti iškviesta iš pagrindinio meniu. Python programavimo kalba eksportavimo priemonėje naudojama nuskaityti 3D scenos duomenis ir juos išsaugoti XML formatu. Ekportavimo priemonėje Java programavimo kalba nuskaitomas bei apdorojamas XML failas, sudaromas 3D elementų hierarchinis medis, sukuriamas M3G failas, sukuriami duomenų masyvai bei sektoriai, kuriuose saugomi 3D scenos duomenys ir į M3G failą eksportuojami 3D scenos duomenys. Eksportavimo priemonė turi galimybę įkrauti eksportuotą M3G failą į mobiliąją aplikaciją ir atidaryti ją Java emuliatoriuje – mobiliajame telefone. Eksportavimo priemonė palyginta su kitomis eksportavimo priemonėmis eksportavus skirtingus 3D modelius į M3G formatą bei palyginus gautus rezultatus pagal 3D objektų savybių bei transformacijų atitikimą pradiniam 3D modeliui, eksportavimo priemonės patikimumą bei kitus kriterijus. / In the master thesis the M3G standard for 3D graphics in mobile phones, its compatibility and possibilities of exporting 3D models to M3G format are investigated. Most popular 3D modelling and exporting to M3G format tools are analyzed. Blender was selected as main master thesis modelling tool for possibility to reach 3D model data using Python scripts. An exporting scheme from Blender to M3G format was created and realized using Python and Java programming languages. The exporter works as a plug-in for the Blender modelling tool. It can be accessed in the main Blender menu. The Python programming language in the exporter was used for extracting data from 3D scene and saving it in XML format. The Java programming language was used for reading 3D data from XML file, making hierarchical 3D elements tree, creating 3D elements tree, constructing data arrays and sectors, where 3D data arrays and sectors are kept and exporting data to M3G file. The exporter can load an exported M3G file to mobile application and show it in Java emulator – mobile phone. On the basis of several 3D models, the created exporter was compared to other exporters using the quality of performance, reliability and other criteria.

Darbe yra apžvelgiamos NURBS paviršių atvaizdavimo realizavimo problemos mobiliesiems įrenginiams. Pagrindinis darbo tikslas yra įsitikinti tokios realizacijos galimumu, bei surasti kiek įmanoma efektyvesnį būdą, išsprendžiantį mobiliųjų platformų realizacijų problemas. Dar vienas tikslas, sukurti prototipinį sprendimą, padengiantį NURBS standartą. Analizei pasirinkta M3G mobiliosios grafikos standartas, kuris šiuo metu yra labiausiai paplitęs. Realizacijų palyginimui buvo pasirinkti du algoritmai: Oslo ir tiesioginis. Atlikus veikimo analizę nustatyta, jog tiesioginis algoritmas yra efektyvesnis, kurio pagrindu buvo išbaigtas NURBS standartas, realizuojant Trimmed NURBS modelius. / In the thesis it is analyzed the problems related with NURBS rendering implementation for mobile devices. The main goal of the thesis is to make find out if such implementation is possible at all and to find most effective way to implement it. One more goal is to create a prototype implementation for NURBS standard including Trimmed NURBS. M3G mobile graphics platform was chosen for analysis, which is mostly adopted across the vendors nowadays. There was chosen two rendering algorithms for analysis purposes: Oslo and directional. During analysis it was discovered, that Directional algorithm is more effective than Oslo, and it was adapted to prototype solution – Trimmed NURBS.

The automation of buildings mainly in the large and office buildings is very discussed issue in nowadays time. The advantages of automated buildings fundamentally consist in the lowering of the operation costs, more safety and the protection of property. The building can be monitored and controlled towards the proceeding processes and states. It is able to use local or remote monitoring and controlling. More comfortable controlling is next important factor. This thesis describes European installation bus EIB and its communication with visualization a control system called Control Web. Control Web communicates with the electronic security system Galaxy for complete monitoring of the whole building. The complex system ensues by the mutual link of these technologies. It is possible to lower effectively the total costs for the business among other things. The result of this project is the developed application in the system Control Web 6, which is used in the building of the company ATX, ltd. in Žďár nad Sázavou. The Visualization is targeted in the two dimensional view and 3D view, which is used very often today. Web representation is used as well because web browser is part of the every operating system. The integral part of visualization is process automatic control.

The master’s thesis submitted deals with realtime rendering of three-dimensional CAD data using Vulkan API. The thesis also covers possibilities of connecting the API with VRUT, complex solution for renderig developed by ŠKODA AUTO a.s. Design of such connection is presented in form of Vulkan rendering plugin for VRUT application. Performance of the designed module is compared with another rendering module, based on different rendering technologies.

This thesis is focused on describing methods of computation of global illumination of 3D graphics scenes in real-time. First chapter contains brief introduction to the issue of global illumination (GI) computation, as well as quick summarisation of principles of most commonly used GI computation approaches. A method of visibility computing for indirect illumination, taking advantage of Imperfect Shadow Mapping, is introduced next. After closer examination of this method and prerequisite algorithms follows a description of its practical implementation, as well as of the structure of simple demonstrative application. Next chapter then contains testing and brief examination and evaluation of resulting program's behaviour. Finally, a possible method extension by means of virtual point light clustering is proposed.

This thesis deals with implementation of a debugging and development tool for GLSL shader programming. In the text, you will find design of the application and it's implementation in Qt library. The thesis also includes performance testing with GLSL shaders. Experiments were focused on commands of application control flow in GLSL and texturing commands used in shaders. In the thesis, you will find explanation of the functionality of some shaders used in OpenGL. Application developed in this thesis, is meant to help with implementation of graphic programs programmed in OpenGL 3.3 or higher.
