This paper proposes a simple real-time method for modeling and rendering clouds. The density of cloud is formed by simulating projected motion of cloud particles into 2D plane. And then we render it by using an algorithm that approximates single forward scattering in real-time. This method does not require any preprocess to shade the cloud. By using this method one can create a cloud very quickly and control the cloud shape in an easy way.
