WebHyperNeRF represents changes in scene topology by providing a NeRF with a higher-dimensional input. This is inspired by level-set methods. Level-set methods provide a means to model a family of topologically-varying shapes as slices of a higher dimensional auxiliary function. For example, these shapes. can be represented as slices through this ...
