Abstract
A scene may be rendered as objects that are lit by various light sources. A scene designer may arrange the scene to create particular lighting effects when viewed from an initial perspective, such as gloss, translucency, and iridescence, and may choose lighting effects to create a desired aesthetic tone and/or highlighting within the scene. However, rendering the scene from a different perspective may alter the lighting effects (e.g., losing or misplacing desired lighting effects, and/or creating new and undesirable lighting effects, such as glare). Instead, when the scene is rendered from the initial perspective, the lighting effects created therein may be stored with the scene representation of the scene. A second rendering of the scene from a different perspective may reapply the stored lighting effects to the lit objects, thereby maintaining the lighting effects and the intent of the designer in the presentation of the scene from a different perspective.
