How to use unity3d terrain data in direct3d 11 environment

Abstract

The invention provides a use method of Unity3D terrain data in the Direct3D 11 environment. Enhanced Unity3D terrain export plug-in comprises a plurality of export submodules. A terrain vertex position and UV information generation module reads terrain vertex data exported by an export module, and a corresponding geometrical triangular face is constructed. A terrain appearance texture array generation module reads a required terrain appearance texture file according to information of a texture set in the export module, and a Direct3D 11 terrain appearance texture array is generated. A blend weight texture generation module generates a Direct3D 11 texture including texture blend weight information in the texture set according to the data exported by the export module. A vegetation position and scaling processing module sets three-dimensional space coordinates of plants in a scene according to vegetation information exported by the export module and conducts size scaling adjustment on plant surface patches. A pixel coloring device calculates light of each pixel on a screen on the basis of three-dimensional rendering element resources, texture samples are mixed in the terrain appearance texture array, and an exported terrain is displayed in the Unity3D 11 rendering environment.

Description

[technical field] [0001] The invention relates to the technical field of computer software, in particular to a Direct3D 11 data processing and display method. [Background technique] [0002] In the prior art, when developing a 3D game or designing 3D simulation software, it is often necessary to load a terrain model into the scene for rendering. Taking the engines developed based on the underlying Direct3D technology as an example, the conventional way to load terrain in these engines is to first use 3D modeling software such as 3DMax to model the terrain, generate the vertex data of the terrain, and paste the texture bitmap ; Then export the data that Direct3D can recognize and use (Direct3D 9 or previous versions use X format files, and Direct3D 10 uses sdkmesh format files). [0003] When using 3DMax software to build terrain, in addition to adjusting the position of each vertex in the terrain model, it is also necessary to use graphics processing software such as PS to ...

AI Technical Summary

Problems solved by technology

The terrain model produced by such an efficient and convenient terrain editor can only be used in the Unity3D environment. Although the existing plug-in can be used to export the vertex position information of the terrain model, only the vertex position information is far from enough. These data are in Direct3D Only the ups and downs of the terrain can be seen in the environment, and all texture information is lost
