System and method for computer-generated holography synthesis

A method comprising:

• obtaining image data associated with a plurality of layers of a 3D scene including a first layer at a first distance from a result layer and a second layer at a second distance from the result layer, wherein the first distance is greater than the second distance;
• determining a plurality of phase increment distributions, wherein each of the plurality of phase increment distributions is associated with a respective one of the plurality of layers for modifying, at the respective one of the plurality of layers, an image size associated with the scene;
• and
• determining an image wave front at each of the plurality of layers based on a propagation of an image wave front from the first layer through the second layer to the result layer to form a propagated image wave front at the result layer representing a hologram of the scene, wherein the propagation includes, for each of the first layer and the second layer, applying a respective one of the plurality of phase increment distributions associated with a layer to the image wave front at the layer.

A wireless transmit receive unit (WTRU) comprising:

• a memory;
• and
• a processor configured to:
• obtain image data associated with a plurality of layers of a 3D scene including a first layer at a first distance from a result layer and a second layer at a second distance from the result layer, wherein the first distance is greater than the second distance;
• determine a plurality of phase increment distributions, wherein each of the plurality of phase increment distributions is associated with a respective one of the plurality of layers for modifying, at the respective one of the plurality of layers, an image size associated with the scene;
• and
• determine an image wave front at each of the plurality of layers based on a propagation of an image wave front from the first layer through the second layer to the result layer to form a propagated image wave front at the result layer representing a hologram of the scene, wherein the propagation includes, for each of the first layer and the second layer, applying a respective one of the plurality of phase increment distributions associated with a layer to the image wave front at the layer.
