Real-Time Rendering of Volumetric Clouds
Rendering volumetric clouds is a compute-intensive process which makes it difficult to use in real-time applications. At the same time, the need for volumetric clouds is evident as game developers look for new places to increase the realism of their games. Skyboxes and flat textures work well in 3D scenes where the camera is expected to be far away from the clouds and not move over large distances
