In-game Interaction with a snowy landscape

Sammanfattning: We present a method for creation and interaction of snow in a computer game engine. This is achieved by generating a local transformable mesh around the player camera and osetting this mesh by a height map. This height map is used both for smoothing the terrain into a random snow landscape as well as for modifying the snow where prints are made. Our method compared to previous implementations has the advantage of everlasting prints in the vicinity of the player. To enhance the visual immersion we make use of lighting eects such as glitter and bloom on a highly detailed surface. The main advantages of using our method is that it is fast and that the performance loss when adding more dynamic models in the local area around the player is minimal.
