Interactive Cartoon Rendering and Sketching of Clouds and Smoke

We present several techniques to generate clouds and smoke with cartoon style and sketching obtaining interactive speed for the graphical results. The proposed method allows abstracting the visual and geometric complexity of the gaseous phenomena using a particle system. The abstraction process is made using implicit surfaces, which are used later to calculate the silhouette and obtain the result image. Additionally, we add detail layers that allow improvement of the appearance and provide the sensation of greater volume for the gaseous effect. Finally, we also include in our application a simulator that generates smoke animations.
