Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0023] In an embodiment of the present invention, a method for loading complex 3D models in 3D virtual simulation is provided, such as figure 1 As shown, the method includes:

[0024] Step 101: Divide the 3D model to be loaded into multiple 3D model blocks;

[0025] Step 102: setting a trigger area for each 3D model block, and the 3D model block is in its corresponding trigger area;

[0026] Step 103: Determine the trigger area where the viewpoint position is currently located, and load the 3D model block corresponding to the trigger area where the viewpoint position is currently located into...

Abstract

The embodiment of the invention provides a loading method and device of a complex three-dimensional model in three-dimensional virtual simulation. The method comprises the following steps: dividing a three-dimensional model to be loaded into a plurality of three-dimensional model blocks; setting a trigger zone for each three-dimensional model block; determining the trigger zone where a viewpoint position is positioned at present, and loading the three-dimensional model block corresponding to the trigger zone where the viewpoint position is positioned at present into a three-dimensional virtual simulation program. The scheme avoids the problem that a client side constantly loads resources from a service side since the each-time viewpoint movement of a user in the model needs to reload the model so as to lower requirements on network transmission.

Description

technical field [0001] The invention relates to the technical field of three-dimensional virtual simulation, in particular to a method and device for loading complex three-dimensional models in three-dimensional virtual simulation. Background technique [0002] Virtual simulation technology creates a three-dimensional simulation environment for users through three-dimensional technology, and users roam and view in the three-dimensional simulation environment through computers. For the loading of models in virtual simulation programs, there are currently two technologies. The first is a one-time loading method, that is, loading the model into the memory at one time; the other is a real-time loading method, that is, according to the user's Viewpoints in , load the model that the user can currently see in real time. [0003] The one-time loading method is relatively simple in logic and relatively easy to implement. Small models can also be loaded normally, but when it is neces...
