WebAssembly usage in Industry 4.0
Chvátal, Petr ; Hůlka, Tomáš (referee) ; Dobrovský, Ladislav (advisor)
The bachelor thesis focuses on the use of the new web standard WebAssembly. In the text of the thesis are described the technologies for web browsers and their use. Furthermore, are described the programming languages that support the WebAssembly web standard. Finally, the thesis presents the implementation of an application in this environment and the translation of an application written in C++ into WebAssembly using the Emscripten tool, evaluating the advantages and disadvantages of using WebAssembly over older web standards.

Processing and Streaming Video in Browser for Screen Recording
Svačina, Lukáš ; Beran, Vítězslav (referee) ; Španěl, Michal (advisor)
Aim of the thesis is to design and implement unique service based on the newest technologies in web apps fi eld which allows screen recording followed by P2P distribution between participating users using web browser only. Thesis deals with the analysis of modern and coming technologies which allow practical implementation of such a service. It involves obtaining access to the screen source data, its recording, transforming and transmission over the network followed by playing on the other side. Recorded videos are adapted for part by part use in a player with seeking capability. Distributed architecture for data exchange between peers using peer-to-peer connection based on hybrid P2P VoD network provides scalability of the solution. The player allows obtaining the necessary parts of the videos from the current watchers with smooth video playback experience during ongoing transmissions whilst allowing arbitrary video shifting. In consideration of early stages of development or experimental support for some of the APIs needed for this work, research into browsers' support with discussion on realistic applicability nowadays is always performed.

WebGL2 Renderer in WebAssembly
Režňák, Pavel ; Lysek, Tomáš (referee) ; Starka, Tomáš (advisor)
This thesis is focused on fast rendering of the 3D scene in a web browser with usage of modern technologies, for instance WebGL and WebAssembly. In this thesis you will find out how to compile an application which was written in C++ language into WebAssembly via Emscripten compilator and how to insert this code into a web page. Futhermore, you will find out how to communicate between C++ language and JavaScript, how to call functions, create instances and how to share memory between them. During design of a rendering core you will learn a few methods how to improve rendering performance. In the end the performance of this technologies is compared.
