Method for performing batch programming on three-dimensional data and automatically reducing surface and baking chartlet

Abstract

The invention discloses a method for performing batch programming on three-dimensional data and automatically reducing surfaces and baking chartlets. The method comprises the following steps of: 1, setting a path of a high-modulus file; 2, obtaining a high modulus B file; 3, endowing a polygonCruncher node; 4, performing area reduction to obtain a low modulus C file; 5, setting a normal angle of a high modulus A file, and setting a discovery angle; 6, cleaning historical records; 7, starting baking; 8, obtaining an output model file; and 9, setting a path and a format file for outputting the model file through the UI tool. Thousands of times of area reduction can be achieved, the basic shape of the model is not changed after area reduction, normal and color chartlets can be baked according to the high-area-number model, unattended programmed batch operation can be achieved, the automation degree is high, the working efficiency is greatly improved, moreover, the consumed time is less, and the labor cost is reduced.

Description

technical field [0001] The invention relates to a method for automatically reducing planes and baking textures in batches for three-dimensional data. Background technique [0002] The data calculated by oblique photography and laser scanning are real and accurate model data, but its disadvantage is that the model has too many faces, which is not suitable for 3D visualization display. The 3D visualization engine based on the game engine cannot handle such a huge The amount of data, and the operating efficiency will be affected due to too many faces. At present, the surface reduction software on the market can only reduce the surface of the model, but when the texture is guaranteed to be correct, the area reduction ratio is limited, and the oblique photography and laser scanning data are huge, and the manual operation takes too long.

[0002] The data calculated by oblique photography and laser scanning are real and accurate model data, but its disadvantage is that the model has too many faces, which is not suitable for 3D visualization display. The 3D visualization engine based on the game engine cannot handle such a huge The amount of data, and the operating efficiency will be affected due to too many faces

At present, the surface reduction software on the market can only reduce the surface of the model, but when the texture is guaranteed to be correct, the surface reduction ratio is limited, and the oblique photography and laser scanning data are huge, and the manual operation takes too long

Therefore, programmatic unattended large-scale surface reduction without shape reduction, and keeping UV and texture distribution correct has become a major problem for 3D visualization workers.
