Space-time varying color palettes

Abstract

We improve on the widely used color palette technique in the context of anime-style rendering. We introduce an event--driven method to dynamically change color rendition in such rendering scenarios. Changes can happen over time or over space and are triggered by pre-defined events. Such events cause the selection of a particular color palette and node--based "strategy trees" help artists to plan and to visualize resulting look changes interactively. As an optimization, we rely on dynamic shading language code generation to prepare colors before rendering, avoiding the limits of render--time methods.
