Problems solved by technology
[0005] The existing methods for displaying the 3D world have no problem dealing with normal-sized objects, but for super-large objects, some of the triangles may be cropped because they exceed the visible range, because part of the super-large object cannot be displayed normally and can only be seen. to part of the very large object
In this case, you can adjust the viewing range to a longer distance. However, although you can see all of the super large object in this way, you need to process all the triangles of the super large object, so that the number of processed triangles will be greatly increased. , thereby greatly reducing game performance, resulting in a poor gaming experience

Embodiment Construction
[0023] In order to solve the technical problems proposed by the present invention, the specific realization of the scheme of the present invention includes:
[0024] Perform world transformation on the scene in the 3D world, transform the scene into the world coordinate system; perform camera and perspective projection transformation on the obtained scene in the world coordinate system, and obtain the coordinates of the scene on the viewing plane; transform the scene on the viewing plane The depth value of each triangle point is minimized, so that the depth value of each point is not greater than 1, so that each triangle point will not be clipped.
[0025] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

The invention provides a processing method for objects in a 3D (three-dimensional) world, which comprises the following steps: performing world conversion on a scene in the 3D world and switching the scene into a world coordinate; performing camera and perspective projection conversion on the scene under the obtained world coordinate, thereby obtaining a coordinate of a scene on a visual plane; and minimizing a depth value of each triangular point on the visual plane and causing the depth value of each point to be not more than 1, thereby preventing each triangular point from being cut off. By applying the processing method for the objects in the 3D world provided by the invention, a huge object in the 3D world can be normally displayed without reducing the game property.
Description
technical field [0001] The invention relates to the technical field of object processing, in particular to an object processing method in a 3D world. Background technique [0002] Currently, each scene in the 3D world is a collection of multiple objects, and each object can be approximated by a triangle mesh, that is, the most basic primitive in the 3D world is a triangle. [0003] Only by correctly displaying the 3D world can players experience a more realistic experience. Currently, the 3D world is usually displayed through the following methods: [0004] After performing multiple data matrix transformations on the scene in the 3D world, the triangles that exceed the visible range are cut off, the triangles that are far away in the scene are added with fog to make them blurred, and the triangles that are beyond the set range are faded out . [0005] The existing methods for displaying the 3D world have no problem dealing with normal-sized objects, but for super-large obj...
