Age is an academic game engine developed in Visitlab/HCI laboratory. Its purpose is to provide a software basis and playground for game development courses. The goal of the thesis is to implement a shader graph module to Age. The module should allow for definition of various visual effect commonly available in contemporary game engines (like Godot, Unreal, Unity) in a user-friendly way. The evaluation of the module should demonstrate the flexibility of the approach (i.e., commonly available effects in the mentioned engines can indeed be easily created) and resulting shaders (running on GPU) are effective (comparable with hand written versions). The text of the thesis will contain the description of the shader graph solutions in available game engines (at least Godot, Unreal, and Unity), the description of the approach chosen for Age, and there will also be presented results from the evaluation of the module.
