Representing 3D shapes with probabilistic directed distance fields

An apparatus for representing shapes with probabilistic directed distance fields, comprising:

• a memory storage storing computer-executable instructions;
• and
• a processor communicatively coupled to the memory storage, wherein the processor is configured to execute the computer-executable instructions and cause the apparatus to:
• obtain 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;
• calculate, 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
• generate renders of geometric information of the scene using the visibility score and the depth of the plurality of rays.

A non-transitory computer-readable storage medium storing computer-executable instructions for representing shapes with probabilistic directed distance fields by a device, the computer-executable instructions being configured, when executed by one or more processors of the device, to cause the device to:

• obtain 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;
• calculate, 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
• generate renders of geometric information of the scene using the visibility score and the depth of the plurality of rays.
