Three-dimensional model data processing method and device based on protocol way

Abstract

The invention provides a more efficient data processing method and device. Through a protocol way, storage sequences and storage contents are defined, data is stored by a binary system, only most important grid data is kept, certain invalid data is removed, and in addition, an effect of data compression is achieved through a way of dynamically distributing storage space is achieved. The technicalscheme of the invention is a three-dimensional model data processing method based on a protocol way. The method comprises the following steps that: coding: coding model file data, and dividing the model file data into a model file header, marshalling information and grid data; and compression: analyzing three-dimensional model grid data, converting parsed model surface data into triangular surfacedata, dynamically arranging standard geometric data and texture data, removing the invalid data, and rewriting the marshalling information and the grid data.

Description

technical field [0001] The invention relates to a processing method for coding and compressing three-dimensional model data, and belongs to the technical field of three-dimensional graphic image processing. Background technique [0002] The 3D model formats commonly used in the market, such as obj, dae, etc., often have several obvious defects. First, they are all in plain text format, which requires a large amount of storage space for very little data. Second, plain text causes File parsing takes more time, and the third is that there are more redundant data. This model is not convenient for direct transmission on the network, and often needs to be pre-packaged in an application program and downloaded to the user's computer for use. [0003] In practical applications, there are many requirements for real-time loading of 3D models. For example, when presenting 3D models on WebGL websites, this requires the size of the model to be as small as possible to prevent users from c...

This model is not convenient for direct transmission on the network, and often needs to be pre-packaged in the application program and downloaded to the user's computer for use

[0003] In practical applications, there are many requirements for real-time loading of 3D models. For example, when presenting 3D models on WebGL websites, this requires the size of the model to be as small as possible, so as to prevent users from causing problems due to long loading times when they visit. Problems such as poor user experience
