Problems solved by technology

Among them, the deferred rendering method draws the terrain by sampling road textures in the deferred rendering stage, but this method does not support implementation on mobile devices; the projector method cannot render custom shapes; the method of creating grids , then use the method of generating a grid based on path sampling points, set sampling points on the terrain system, sample the height of the terrain, and generate a road model, but this method also has problems that cannot completely fit the terrain, and the fineness of the road grid is not enough Defects

Abstract

A method and device for creating a road grid based on a terrain system of a Unity engine, the method comprising the steps of: acquiring sampling points from a scene, creating a road curve; acquiring vertices of a segmented grid, creating a vertex preparatory array; creating a segmented grid The bounding box and cutting plane of the vertices of the lattice; create a secondary vertex preliminary array; create a triangle index array of the secondary vertex preliminary array; use the cutting plane to cut the secondary vertex preliminary array to obtain the child vertex preliminary array, and reorganize the triangle index array Obtain the child triangle index array; based on the cut surface, obtain the UV array of the child vertex preparation array; use the child vertex preparation array, the child triangle index array, and the UV array to create a road mesh. The method and device for creating a road grid based on the terrain system of the Unity engine of the present invention can create a road model that completely fits the terrain system of the Unity engine.

Description

technical field [0001] The invention relates to the technical field of image modeling, in particular to a method and device for creating a road grid based on a terrain system of a Unity engine. Background technique [0002] Unity is a multi-platform comprehensive 3D graphics engine developed by Unity Technologies that allows developers to create interactive content such as 3D video games, architectural visualization, and real-time 3D animation. Other current game engines, such as CryENGINE3 engine, Unreal 4 engine, etc., all provide editing tools for creating roads based on the terrain system of the Unity engine, but the Unity engine does not provide developers with editing tools for creating roads based on the terrain system of the Unity engine. . [0003] The editing tool for creating roads is a tool that can create simulated real-world road models in virtual three-dimensional space. The functions of the editing tools for creating roads generally include: customizing the...
