Methods and systems for using dynamic lightmaps to present 3D graphics

Abstract:

Illustrative methods and systems described herein use lightmaps to present 3D graphics. For example, a method includes identifying a viewpoint within a 3D scene and receiving a dynamic lightmap for an object represented by a 3D model in the 3D scene. The identified viewpoint is selected by a user of a media player device presenting the 3D scene to the user and the dynamic lightmap is generated or updated at a first level of detail determined based on the identified viewpoint. The method further includes rendering an image for presentation to the user from the identified viewpoint. This rendering of the image includes rendering the 3D model at a second level of detail that is lower than the first level of detail, and applying the dynamic lightmap at the first level of detail to the 3D model rendered at the second level of detail. Corresponding systems are also disclosed.
