US 2018/0018812 A1 · PRESERVING SCENE LIGHTING EFFECTS ACROSS VIEWING PERSPECTIVES

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.

Dependent claims

A method of presenting a scene of objects lit by a light source, the method using a processor of a device and comprising:

executing, by the processor, instructions that cause the device to:
generate a first rendering of the objects of the scene from an initial perspective, including rendering the light source upon a lit object to produce a lighting effect from the initial perspective;
store the first rendering of the objects of the scene, including the lighting effect upon the lit object;
and
responsive to a request to render the scene from a second perspective:
generate a second rendering of the objects of the scene from the second perspective while maintaining the lighting effect upon the lit object from the initial perspective;
and
present the second rendering to fulfill the request.

A method of representing a scene of objects using a processor of a device and a data store, the method comprising:

executing, by the processor, instructions that cause the device to:
receive a scene representation of the scene comprising:
a set of object models for the respective objects of the scene,
a light source positioned within the scene, and
an initial perspective for lighting the scene;
render the light source upon an object model of a lit object of the scene to produce a lighting effect from the initial perspective;
and
store, in the data store, a scene representation of the scene comprising:
the object models;
and
the lighting effect from the initial perspective.

8 more elements

A device that presents a scene of objects, the device comprising:

a data store that stores a scene representation of the scene comprising:
a set of object models of the respective objects of the scene, and
a lighting effect generated upon a lit object of the scene by a light source when rendered from an initial perspective;
and
a processor that generates a rendering of the scene from a second perspective by:
rendering the object models of the respective objects from the second perspective, and
rendering the lighting effect upon the lit object maintained from the initial perspective;
and
a presenter that presents the rendering of the scene from the second perspective, including the lighting effect upon the lit object from the initial perspective.
