1. A method of representing shapes with probabilistic directed distance fields to be performed by a processor, comprising:
obtaining a camera representation and a latent shape vector representation of a scene, the camera representation indicating position information and direction information of a view of the scene;
calculating, based on the latent shape vector representation of the scene, a visibility score and a depth for each ray of a plurality of rays emanating from a corresponding plurality of positions and directions, the plurality of positions and directions being determined from the camera representation of the scene; and
generating renders of geometric information of the scene using the visibility score and the depth of the plurality of rays.
