Map data reconstruction processing system used for 3D model and processing method thereof

Abstract

The invention provides a map data reconstruction processing system used for a 3D model. The map data reconstruction processing system comprises a model import module which imports a model to be processed, a slice processing module which is connected with the model import module and performs scan slice processing of which the scan line passes through all map vertexes on the model to be processed, a slice dissecting module which is connected with the slice processing module and performs dissecting processing on the model slices processed by the slice processing module, a slice map drawing module which is connected with the slice dissecting module and reads the RGB value of the map from one scan point to another based on the slices and writes the RGB value in a new map image and calculates new map UV coordinates when scanning to the vertexes, a model updating module which is connected with the slice map drawing module and updates the model according to the map result drawn by the slice map drawing module, and a model output module which is connected with the model updating module and outputs the updated module. The invention also discloses a map data reconstruction processing method used for the 3D model.

Description

technical field [0001] The invention relates to the field of 3D model processing, in particular to a texture data reconstruction processing system and processing method for 3D models. Background technique [0002] In 3D model rendering, the object is composed of 3D triangular faces, and the hardware GPU performs rendering and calculation based on each triangular face. Therefore, the more triangles there are, the more calculations the GPU needs to perform. Therefore, in order to ensure high efficiency and high frame rate in 3D model rendering, it is necessary to reduce the number of triangles. In 3D virtual technology, due to the existence of various texture generation algorithms, the UV information (ie texture coordinate information) in the patch fixed point information of the 3D model is not continuous. In the surface reduction calculation of the 3D model, in order to improve the surface reduction effect to a greater extent, it is necessary to ensure that the texture coor...

AI Technical Summary

Problems solved by technology

In the surface reduction calculation of the 3D model, in order to improve the surface reduction effect to a greater extent, it is necessary to ensure that the texture coordinates of the mesh are continuous. After that, the model is deformed and distorted due to the loss of a lot of patch vertex data, which affects the rendering effect
