Generating three-dimensional virtual scene

A system for generating a three-dimensional (3D) virtual scene, the system comprising:

• one or more processor devices, operatively coupled to a non-transitory computer-readable storage medium, the processor devices being configured to:
• obtain, using a model acquiring device, a three-dimensional model of a 3D object corresponding to a two-dimensional (2D) object in a 2D picture based on a predefined mapping relationship, the 3D object obtained from a model database in response to a user selection;
• calculate, using a position mapping device, a corresponding position of the 3D object corresponding to the 2D object in a plane of the 3D virtual scene according to a position of the 2D object in the 2D picture;
• and
• simulate, using a simulation device, a falling of the model of the 3D object onto a landing point on the 3D virtual scene from a predetermined height above the 3D virtual scene, wherein a position of the landing point of the model of the 3D object in a horizontal plane is a corresponding position of the 3D object in the horizontal plane of the 3D virtual scene.

A non-transitory computer program product for generating a three-dimensional (3D) virtual scene, the computer program product comprising one or more computer readable storage media having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to perform a method comprising:

• obtaining a three-dimensional model of a 3D object corresponding to a two-dimensional (2D) object in a 2D picture based on a predefined mapping relationship, the 3D object obtained from a model database in response to a user selection;
• calculating a corresponding position of the 3D object corresponding to the 2D object in a plane of the 3D virtual scene according to a position of the 2D object in the 2D picture;
• and
• simulating a falling of the three-dimensional model of the 3D object onto a landing point on the 3D virtual scene from a predetermined position adjacent to the 3D scene, wherein a position of the landing point of the three-dimensional model of the 3D object in the plane is the corresponding position of the 3D object in the plane of the 3D virtual scene.
