Abstract
Snow is a kind of complicated objects that has irregular shape. Therefore, the topic of snow three-dimensional visualization is always challenging. The real-time rendering accumulated snow is of great importance to improve reality in the scene simulation. In this paper, we put forward an algorithm based on predecessors which introduces Perlin Noise and smoothing algorithms, combining with incline coefficient and exposure coefficient. This algorithm makes snow accumulation more natural. Rendering by combining geometry and texture, complexity of large-scale scene is dropped off sharply. Using occlusion map which is processed by image processing, this algorithm could update occlusion relationship of objects in the scene and get better results. Experiment results show that the proposed algorithm accelerates the rendering and be suitable for large real-time snow accumulated rendering.
