Interactive Cloud Modeling and Animation Software

Summary: Researchers at Purdue University have developed an intuitive, interactive, physics-based system to artistically model, animate, and render visually convincing volumetric clouds using modern consumer graphics hardware. The simulation is controlled using a set of intuitive, high-level primitives. The animation of the implicit skeletal structures and independent transformation of octaves of noise emulate various environmental conditions. The resulting interactive design, rendering, and animation system produces perceptually convincing volumetric cloud models that can be used in interactive systems.

*Abstract

*Background: Amorphous phenomena, like clouds and dust, elude traditional modeling techniques with their peculiar patterns of intricate, ever-changing volume-filling microstructures. Modeling these structures has been a difficult task that has been addressed in many different ways. Current techniques can produce high quality images; however, the image generation tends to be slow.
