Description

Technical Field

[0001] The present invention relates to the technical field of game development, and particularly relates to a method for automatically converting a planar map into a curved surface map. Background Art

[0002] A curved surface map is a special display scheme for maps. The representative game using this scheme is "Microsoft Flight Simulator" ( Figure 1 ). Different from conventional planar maps, curved surface maps have a greater depth of field, better long-distance performance, and a sense of space. However, the implementation scheme of curved surface maps in traditional games is generally achieved by modifying vertex offsets in each Shader that requires curved surface performance. Since map components, as well as characters and special effects presented on the map, all need to be processed, the production process is complex and the maintenance cost is high. Therefore, the present application provides a method for automatically converting a planar map into a curved surface map to meet the requirements. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a method for automatically converting a planar map into a curved surface map to solve the problems of complex existing production processes and high maintenance costs.

[0004] To solve the above technical problems, the present invention provides the following technical solutions:

[0005] A method for automatically converting a planar map into a curved surface map, comprising the following steps:

[0006] S1, establish a syntax analyzer for Shader;

[0007] S2, automatically process all static resources;

[0008] S3, encapsulate a switching interface, and in the form of a macro switch, switch the performance of the same resource in the planar map and the curved surface map with one key;

[0009] S4, establish a visualization tool to facilitate artists to quickly check and view the effects.

[0010] In a possible implementation manner, the syntax analyzer in S1 includes the processing of Shader by the curved surface map. The processing of Shader by the curved surface map is mainly divided into two parts:

[0011] a, correct the Y value of the vertex through a specific formula;

[0012] b, correct the alpha of the pixel output color.

[0013] In a possible implementation, the syntax analyzer in S1 further includes semantic analysis. The semantic analysis mainly finds the corresponding keywords and performs syntax block and matching analysis. The keywords involved in the two parts of the Shader processing by the surface map are Position in the vertex structure and return in the PixelShader respectively.

[0014] In a possible implementation, the Position keyword corresponds to the vertex coordinates to be processed. The subsequent vertex coordinate processing link includes various MVP conversion logics of the VertexShader. The vertex coordinate processing link needs to perform syntax block replacement. The return keyword in the PixelShader needs to add special processing for the alpha value of the return value before returning.

[0015] In a possible implementation, the syntax analyzer in S1 further includes a Shader template for processing certain special syntax implementations. For example, the clip function has a direct sequence relationship with the alpha of the color, and the relevant syntax segments need to be shifted.

[0016] In a possible implementation, the syntax analyzer in S1 further includes the Unity's SurfaceShader, and the Unity's SurfaceShader requires special syntax logic.

[0017] In a possible implementation, S2 specifically includes the following steps:

[0018] S21, taking the camera Layer as a distinguishing mark, in a non-running environment, statically scan the resources and analyze the Shaders used by the resources;

[0019] S22, using the syntax analyzer of S1 and substituting a templated processing method, automatically generate a surface version for the Shaders that need surface conversion and replace the corresponding materials.

[0020] In a possible implementation, the automated process in S2 will judge the situation where the map resources and the interface resources use the same material, and generate a new material to ensure the uniqueness of the surface material.

[0021] Compared with the prior art, the present invention has at least the following beneficial effects:

[0022] Through the syntax analyzer for Shader, the vertex processing code segment and the pixel alpha assignment code segment can be located, and the templatized replacement of the surface processing logic can be performed. On this basis, a set of standard Shader templates are constructed, with the camera Layer as the distinguishing mark. In the non-runtime environment, the resources are statically scanned, the Shaders used by the resources are analyzed, and in a templatized processing manner, the Shaders that need to perform surface conversion are automatically generated with surface versions and the corresponding materials are replaced, which improves work efficiency and reduces maintenance costs at the same time.
