Realistic image synthesis of highly complex, natural scenes has been a challenging topic in computer graphics over the years. Generation of snowy scenery could be even more difficult due to the difficulty of using common modelling primitives such as polygons and curved surfaces to express the snow-like shapes. In this paper, we propose a hybrid multi-mapping method to tackle the snowy scenery problem, in which a displacement map is utilized to model snowy blocks on near objects based on proximate polygons, and a volumetric texture map is combined to handle distant objects such as bushes and trees. Our experimental results showed that the hybrid method is viable in producing realistic snowy scenery with comprehensive complex environments, and in a favourable requirement of storage usage and rendering computation.
