Abstract: 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.

Abstract: A conditional adversarial latent model (CALM) process can be used to generate reference motions from a set of original reference movements to create a library of new movements for an agent. The agent can be a virtual representation various types of characters, animals, or objects. The CALM process can receive a set of reference movements and a requested movement. An encoder can be used to map the requested movement onto a latent space. A low-level policy can be employed to produce a series of latent space joint movements for the agent. A conditional discriminator can be used to provide feedback to the low-level policy to produce stationary distributions over the states of the agent. A high-level policy can be employed to provide a macro movement control over the low-level policy movements, such as providing direction in the environment. The high-level policy can utilize a reward or a finite-state machine function.
