Webpage end three-dimensional model annotation information display browsing method and system

Abstract

The invention aims to provide a webpage end three-dimensional model annotation information display browsing method and system capable of displaying three-dimensional model annotation information on awebpage end. The display browsing method comprises the following steps: S1, preprocessing a three-dimensional model to generate a lightweight model file and an annotation information object; s2, preprocessing the annotation information object to obtain an annotation type, an annotation guide line, an annotation value and annotation plane data; s3, performing integer processing on the normal vectordata of the labeling plane to reduce the number of bytes stored in the normal vector data; s4, carrying out json processing on the annotation information object, and generating an annotation information file with the storage suffix being json; s5, when the front end reads the lightweight model file, redrawing the annotation information according to the data structure of the annotation information, and then rendering the scene by using webgl; and S6, designing a dynamic display algorithm of the annotation information, and achieving automatic overturning and position changing of the annotationinformation along with the change of the model attitude.

AI Technical Summary

Benefits of technology

This patented technique allows users to see how their models are being annotated with annotations by showing them online or through an interface like WebGL. It uses rotating and tilting animation techniques to show different versions of these markers over time. By analyzing this data it can help identify which parts have been added during training process. Overall, this approach helps create accurate visual representations of 3 D modelling markup (TM) content without requiring manual effort from developers who already know what they should look at when adding new details).

Problems solved by technology

This patented technical problem addressed by this patents relates to displaying 3D objects like those made from computerized tomography imagery (CT). Current methods require parsing or converting large amounts of raw 3D object data before it becomes usable on websites such as Internet Explorer® due to its heavy weight compared to other types of media. Additionally, there may also be issues where customers have difficulty understanding how different parts look together accurately because they cannot easily distinguish between them visually.
