Summary
This bachelor thesis examines current options of real-time water surface simulation and its possible optic properties affecting the water surface itself or object laying underneath it. The contents of the analysis are not only the current methods of simulating dynamic and optic properties of a water surface but also technologies supporting its real-time rendering. The practical part is dedicated to the design of the water surface simulator, which uses wave equation as the main method for approximation of its movement, and the application of the testing scene and subsequently its implementation. Water surface optic properties such as reflection, refraction and caustics are then implemented with simplified method of ray-tracing which approximates light ray intersections in the screen space using auxiliary textures. Final water surface deforms after user interference and subsequently reacts optically on surrounding environment by casting caustics on underwater objects and by calculating water surface color from Fresnel equations. At the end deficiencies of used algorithms in the final version of the application, which lay in the method of integration of the wave equation and in the method of light ray intersection approximation, are stated.

Summary
The ElateMe system is a combination of social network and crowdfunding platform. It helps users to create own wishes and contribute to the others. Simply said, the ElateMe system solves the problem of giving a suitable gift to a family member, a friend or a colleague. The ElateMe system is integrated into Facebook authorization systems, so a user does not even need to create an ElateMe account in order to use the system. Applications for the ElateMe system are available on different platforms such as web browsers, Android and iOS. Applications use a backend server, which manages wishes, contributions, sending various notifications and so on. The goal of this thesis is to continue to develop the ElateMe application for the Android operating system, which was started by Georgii Solovev in his thesis. First of all, it is needed to analyze and implement new user re- quirements, such as wish managing, handling of contributions, new methods of payment (wish bank card, PayPal, bitcoins and Android Pay). Existing application architecture may be improved if necessary, and all critical bugs should also be fixed. Finally, it is required to write appropriate tests for the application's code and automate them. This text contains the new requirements analysis and design, updated plat- form specific diagrams, description of important changes of the application ar- chitecture, an introduction to the application's code testing and automation. The new customer's requirements (especially payments) were successfully im- plemented and described with appropriate UML diagrams. The application's code tests were created and successfully automated.

Summary
This master's thesis is focused on creating an alternative to traditional input handling in VR applications, by using a universal gesture system. The gesture system is not using any physical inputs, such as buttons on a controller, so it can be used on basically any existing VR hardware, be it mobile, console or PC VR. The system enables developers to create their own gestures, using VR hardware with motion tracking, and connect that gesture to a function from the application, be it gesture made with just one hand or, for example, all five fingers. The thesis contains research of current VR products and other systems using gestures, and based on this research, the gesture system is designed and implemented. The gesture system adds gesture functionality to any Unreal Engine project and makes that application usable on most VR products, so that the developer doesn't have to worry about making product-specific changes to the application.
