Three-dimensional model gesture touch browsing interaction method based on mobile terminal

Abstract

The invention provides a three-dimensional model gesture touch browsing interaction method based on a mobile terminal. The method comprises fourteen steps. According to the three-dimensional model gesture touch browsing interaction method based on the mobile terminal, application three-dimensional figure programmatic interface OpenGL ES (OpenGL for Embedded Systems) is used for rendering a light three-dimensional model on the mobile terminal (lightweight and rendering methods are not discussed in the invention.), a novel human-computer interaction mode is provided through a gesture identification method, the defects of a traditional desktop side three-dimensional model browsing mode are effectively overcome, portability is improved, and the method is applicable to more application occasions; a natural interaction mode between fingers and the three-dimensional model is achieved, and is more flexible, more visual and more efficient compared with an interaction mode based on devices such as a mouse and a keyboard.

Description

technical field [0001] The invention belongs to the field of information technology, and relates to a three-dimensional model gesture touch browsing interaction method based on a mobile terminal, which can be popularized and used in fields such as virtual reality, human-computer interaction, and digital manufacturing. Background technique [0002] At present, desktop CAD software such as CATIA, Pro / E, UG, SolidWorks, etc. have increasingly powerful functions in 3D modeling and surface modeling, and at the same time support the browsing of 3D model information in most formats. However, when using CAD system to design products, the established product information model is usually composed of product structure shape, modeling process, engineering constraints, feature attributes and other information, resulting in the preservation of a large amount of non-geometric information in the 3D design model. The above information is very important for design engineers, but for others, o...

AI Technical Summary

Problems solved by technology

[0004] 1) The portability of model browsing is poor

Limited to the operating system environment, all kinds of CAD software cannot run without the PC desktop, which brings inconvenience to users and reduces work efficiency to varying degrees

[0005] 2) The way of human-computer interaction is backward

Relying on the desktop hardware, most CAD software still relies on the mouse and keyboard to perform operations such as panning, zooming, and rotating the 3D model to browse. Although the target function can be achieved, the interaction method is not natural and friendly
