Apparatus, method, and computer program for network communications

An apparatus comprising at least one processor and at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus to perform:

• providing, to a computing entity, at least one parameter associated with a device, wherein the at least one parameter is for an environment viewable by the device;
• receiving, from the computing entity via a network, information related to a depth map comprising at least one depth value, wherein the depth map is associated with the environment, and wherein the depth map comprises a plurality of pixels;
• for a pixel of the depth map:
• determining whether a depth value of the pixel is the same as a stored pixel at the device using i) the at least one parameter and ii) at least one geometry library comprising geometry information about the environment, and
• based on the determining, updating information stored in the at least one geometry library;
• rendering an image for display using the i) the at least one parameter and ii) the at least one geometry library;
• providing, to the computing entity, at least one further parameter associated with the device, wherein the at least one further parameter is for the environment;
• receiving, from the computing entity via the network, information related to a further depth map, wherein the further depth map is associated with the environment, and wherein the further depth map comprises a plurality of pixels;
• for a pixel of the further depth map:
• determining whether a depth value of the pixel is the same as a stored pixel at the device using i) the at least one further parameter and ii) at least one geometry library comprising geometry information about the environment, and
• based on the determining, updating information stored in the at least one geometry library;
• and
• rendering an image for display using i) the at least one further parameter and ii) the at least one geometry library.

A method comprising:

• receiving, from a device, at least one parameter associated with the device, wherein the at least one parameter is for an environment viewable by the device;
• generating a depth map associated with the environment, wherein the depth map comprises a plurality of pixels;
• for a pixel of the depth map:
• determining a depth value for the pixel using:
• i) the at least one parameter and ii) at least one geometry library comprising geometry information about the environment, and
• storing the determined depth value of the pixel in the depth map;
• providing, to the device via a network, information related to the depth map comprising the determined depth value;
• receiving, from the device, at least one further parameter associated with the device, wherein the at least one further parameter is for the environment;
• generating a further depth map associated with the environment, wherein the further depth map comprises a plurality of pixels;
• for a pixel of the further depth map:
• determining a further depth value for the pixel using:
• i) the at least one further parameter and ii) the at least one geometry library,
• comparing the further depth value for the pixel of the further depth map to the depth value of the pixel of the depth map, and
• when it is determined that the depth values are different, storing the further depth value of the pixel in the further depth map;
• and
• providing, to the device via the network, information related to the further depth map.
