Nvidia patents 3D models that add fine details on demand
Nvidia describes a method for making 3D models look sharper when users zoom in. It uses AI to generate new, high-resolution images of specific parts of the model and adds them to the original data to create finer details.
In the filing’s own words
Systems and methods of the present disclosure include providing higher levels of detail (LODs) for generated three-dimensional (3D) models, such as those represented by neural radiance fields (NeRFs). A 3D model may be presented to a user in which the user may request additional LODs, such as to zoom into the image or to receive information about features within the image. A request to generate finer levels of detail may include using one or more diffusion models to generate images at higher resolutions and/or to hallucinate finer details based on information extracted from the original image or text prompts. Newly generated images may then be added to a set of images associated with the 3D models to enable later model generation to have finer details.
What exactly they claim (claim 1)
1. A computer-implemented method, comprising: determining a target level of detail for a three-dimensional (3D) volume; generating, using an image generation network and based at least on a current view representing the 3D volume, an updated view representing a selected portion of the 3D volume at the target level of detail, wherein at least a portion of the 3D volume is removed in the updated view; providing, responsive to the target level of detail, the updated view; adding the updated view to a set of images associated with the 3D volume; and updating the 3D volume, based at least on the updated view.
