Abstract
A three-dimensional model distribution method includes: distributing a first model, which is a three-dimensional model of a target space in a target time period, in a first distribution mode; and distributing a second model, which is a three-dimensional model of the target space in the target time period and makes a smaller change per unit time than the first model, in a second distribution mode different from the first distribution mode.
Claims11
A receiving method, performed by a terminal, comprising:
- receiving a first encoded three-dimensional (3D) model and a second encoded 3D model from a distribution apparatus;
- and
- decoding the first encoded 3D model and the second encoded 3D model according to a first decoding scheme and a second decoding scheme different from the first decoding scheme to generate a first 3D model and a second 3D model, respectively, wherein
- the first 3D model and the second 3D model indicate 3D positions of a first object and 3D positions of a second object during a period, respectively, the first object being different from the second object in a 3D space, and
- a motion change of the first object in the period is greater than a motion change of the second object in the period.

A terminal comprising:
- a receiver configured to receive a first encoded three-dimensional (3D) model and a second encoded 3D model from a distribution apparatus;
- and
- a processor coupled to the receiver, the processor being configured to decode the first encoded 3D model and the second encoded 3D model according to a first decoding scheme and a second decoding scheme different from the first decoding scheme to generate a first 3D model and a second 3D model, respectively, wherein
- the first 3D model and the second 3D model indicate 3D positions of a first object and 3D positions of a second object during a period, respectively, the first object being different from the second object in a 3D space, and
- a motion change of the first object in the period is greater than a motion change of the second object in the period.

A terminal comprising:
- a receiver configured to receive from a distribution apparatus:
- a first model indicating three-dimensional (3D) positions of a first object in a 3D space at a first timing;
- and
- a difference model indicating difference between the first model and a second model, the second model indicating 3D positions of the first object in the 3D space at a second timing different from the first timing;
- and
- a processor coupled to the receiver, the processor being configured to generate the second model based on the first model and the difference model.
