Problems solved by technology

[0005] Frustum culling is based on the range of the camera’s viewing angle, and only removes the object models outside the camera’s viewing range, but does not perform any processing on the object models within the camera’s viewing range. The current screen data volume of the 3D video game to be rendered remains Relatively large, the scene management and visibility judgment optimization of 3D video games have not achieved the best results, causing delays and / or freezes when the client renders the current screen of 3D video games, especially for hardware with low performance The client, the situation is more serious, affecting the player's experience

Embodiment Construction

[0035] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0036] In order to further remove object models in the 3D video game screen on the basis of the existing frustum culling method, so as to reduce the amount of data in the rendered 3D video game screen, the method provided by the embodiment of the present invention adopts the camera viewing angle range The occlusion relationship exclusion method in the three-dimensional video game determines the invisible object model within the camera viewing angle range in the current picture of the three-dimensional video game, and then removes the determined invisible object model. In this way, since the occluded object model is eliminated, it does not affect the scene effect of the rendered 3D video game current screen, which ensures the player's experience and achie...

Abstract

The invention discloses a method and a device for culling object models from three-dimensional video game pictures. Invisible object models in a camera view angle of the current picture of a three-dimensional video game are determined in a manner of exclusion of hiding relations in the camera view angle, then the determined invisible object models are culled, and the volume of data for rendering the current picture of the three-dimensional video game is further reduced; the hidden object models are culled, so that the scene effect of the current rendered picture of the three-dimensional video game is not affected, and the experience of a player is guaranteed.

Description

technical field [0001] The invention relates to a processing technology for a three-dimensional picture, in particular to a method and a device for removing an object model in a three-dimensional electronic game picture. Background technique [0002] Video games are developing in the direction of large-scale three-dimensional video games. In 3D video games, the requirements for the experience of 3D video game screens are getting higher and higher. With the continuous improvement of the refinement and size of the scenes of 3D video games, the picture data to be processed increases geometrically, and the client is running 3D video games. When playing games, its hardware processing capabilities can no longer meet the real-time rendering requirements of 3D video games. At this time, it is necessary to perform a set culling operation on the screen currently displayed by the 3D video game, thereby reducing the amount of geometric data of the screen data in each rendering to impro...
