Visual Simulation of Rain

The project of the thesis focuses on increasing visual diversity in traffic simulators by simulating multiple rain phenomena, which can be seen in the real world. Thorough research of existing methods should help to decide which rain effects can remarkably modify how outdoor scenes appear. The rainy weather in several racing games is then being analyzed and visually compared, which later forms a general idea of the rain simulation design. The work also describes how each rain phenomena is implemented in the Unity game engine with the use of an external plugin OctaneRender for ray-traced outputs.
