Embodiment Construction

[0043] Attached below figure 1The present invention is further described.

[0044] Step 1, create a database.

[0045] Put the Mono.Data.Sqlite.dll file and the System.Data.dll file in the Assets folder of the Unity3D game engine as the basic file of the internal database of the Unity3D game engine.

[0046] The environment database, event database and character database are respectively established in the internal database basic file of the Unity3D game engine, and the generated database files are stored in the same level as the Assets folder in the .db format by default.

[0047] Step 2, establish a static virtual environment.

[0048] Using 3D modeling software, generate a base environment model.

[0049] Import the basic environment model into the Unity3D game engine in .fbx format, convert it into a static virtual environment, and store it in the Environment folder of the Project panel. The static virtual environment includes space size, obstacles, roads, and environme...

Abstract

A Unity 3D based three-dimensional virtual crowd scene generating method includes 1, establishing a database; 2, establishing a static virtual environment; 3, creating an event; 4; creating figure models; 5, creating a story control object and constructing an event tree, an event trigger generation sub object, an event selection sub object, an event confliction detection sub object and a crowd dynamic generation sub object in the story control object; 6, calling the story control object by a game engine to generate a three-dimensional virtual dangerous environment; 7, implementing the construction of the three-dimensional virtual dangerous environment. According to the invention, uniform design of crowd, environment and event is preformed, function completeness is achieved. By employing assemblies and plug-ins provided by the Unity 3D game engine, development operation is simplified. The invention synthesizes basic design elements required for virtual crowd scene development, improves efficiency of virtual crowd dangerous scene generation and similar game environment development and has advantages of function completeness and high development efficiency.

Description

technical field [0001] The invention belongs to the technical field of computers, and further relates to a method for generating a three-dimensional virtual crowd scene based on Unity3D in the technical field of computer graphics. The invention is mainly used to generate large-scale crowds and related environments, events, etc. in the virtual world, and realize the rapid establishment of complex crowd simulation scenes. The scene generation method can be used in the development of simulation technology, the simulation of large-scale crowds and related environments, events, etc., and the development of related game scenes. As a basic research in related fields such as game development and public security, the present invention uses the modules and plug-ins of the Unity3D game engine for development, involves specific operation techniques, and can effectively simplify the operation of the scene design. Background technique [0002] Virtual scenes composed of large-scale crowd...
