A Framework for User Control on Stylized Animation of Gaseous Phenomena

Abstract

We present a novel approach to create stylised animations of gaseous phenomena. Existing computer-assisted systems employ computational physics-based approaches which generate 3D effects. Unfortunately, these effects usually don't look like traditional animation, nor can the user freely design the behaviour of the animation. Our approach combines benefits from existing 2D and 3D approaches integrating them in an unusual but effective way. Extendign the application of particle systems, the particle paths vary both with time and with the 3D viewing direction. Rendering features such as smoothly varying common outlines and speedlines help to preserve the animator's artistic style. the incorporation into a structured 2D modelling and animation environment enables a stylised animation exhibiting a convincing frame-to-frame coherence and allows 3D camera movement without aliasing artefacts. The provided solution demonstrates how an animator can remain in full control of a stylised process for effects animation and how one framework is suitable for a wide range of effects.
