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

A system comprising:

• a memory storing instructions;
• and
• a processor communicatively coupled to the memory and configured to execute the instructions to:
• identify a viewpoint within a 3D scene, the viewpoint selected by a user of a media player device presenting the 3D scene to the user;
• receive a dynamic lightmap for an object represented by a 3D model in the 3D scene, the dynamic lightmap generated or updated at a first level of detail determined based on the identified viewpoint;
• and
• render an image for presentation to the user from the identified viewpoint, wherein the processor renders the image by performing operations including:
• rendering the 3D model at a second level of detail that is lower than the first level of detail, and
• applying the dynamic lightmap generated or updated at the first level of detail to the 3D model rendered at the second level of detail.

A non-transitory computer-readable medium storing instructions that, when executed, direct a processor of a computing device to:

• identify a viewpoint within a 3D scene, the viewpoint selected by a user of a media player device presenting the 3D scene to the user;
• receive a dynamic lightmap for an object represented by a 3D model in the 3D scene, the dynamic lightmap generated or updated at a first level of detail determined based on the identified viewpoint;
• and
• render an image for presentation to the user from the identified viewpoint, wherein the processor renders the image by performing operations including:
• rendering the 3D model at a second level of detail that is lower than the first level of detail, and
• applying the dynamic lightmap generated or updated at the first level of detail to the 3D model rendered at the second level of detail.
