    iCheat: A Representation for Artistic Control of Indirect Cinematic Lighting

  • Original language description

    Thanks to an increase in rendering efficiency, indirect illumination has recently began to be integrated in cinematic lighting design, an application where physical accuracy is less important than careful control of scene appearance. This paper presentsa comprehensive, efficient, and intuitive representation for artistic control of indirect illumination. We encode user's adjustments to indirect lighting as scale and offset coefficients of the transfer operator. We take advantage of the nature of indirect illumination and of the edits themselves to efficiently sample and compress them. A major benefit of this sampled representation, compared to encoding adjustments as procedural shaders, is the renderer-independence. This allowed us to easily implementseveral tools to produce our final images: an interactive relighting engine to view adjustments, a painting interface to define them, and a final renderer to render high quality results.

    iCheat: Reprezentace pro umělecké řízení nepřímého osvětlení

  • Czech description

    Díky zvýšení efektivity renderingu se v nedávné začalo prosazovat použití nepřímého osvětlení v kinematografickém nasvěcování, aplikaci kde fyzikální přesnost je méně důležitá než důkladná kontrola vzezření scény. Tento článek prezentuje reprezentaci prouměleckou kontrolu nepřímého osvětlení. Uživatelovy úpravy jsou zakódovány pomocí multiplikativních a aditivních faktorů operátoru přenosu světla.
