Abstract

The invention discloses a mobile device-oriented multi-point touch gesture interaction three-dimensional modeling method. The method mainly comprises the steps of initializing a three-dimensional modeling space; defining a three-dimensional modeling operation function set in the three-dimensional modeling method, wherein the function set comprises generation, control and editing function operation subsets, and multi-point touch gesture behavior subsets corresponding to function operations; performing single-finger or multi-finger gesture interaction operation and monitoring on a touch screen supporting multi-point touch; and identifying gesture operations, mapping identified gesture operation behaviors to a three-dimensional modeling function and performing calling. According to the method, the corresponding three-dimensional modeling operation can be performed on a mobile device by combining multi-point touch gestures, so that the shortcomings of finite screen space and inaccurate clicking of the mobile device are overcome; the method has the advantages of quickness in modeling, low learning cost and intuitiveness in use; and a three-dimensional modeling system solution suitable for a mobile platform is given.

Description

technical field [0001] The present invention is applied to mobile devices supporting multi-touch technology, and in particular relates to a mobile device-oriented multi-touch gesture interaction three-dimensional modeling method. Background technique [0002] With the continuous development of mobile device CPU, memory, display and other hardware technologies and the increasingly perfect development environment of intelligent operating systems, the applications based on mobile devices are becoming more and more abundant. Some traditional software companies and institutions are also studying the transplantation of their PC applications. to the mobile platform. In the field of 3D modeling, some companies have launched modeling systems for their mobile platforms, such as AutoCAD, ZWCAD, etc., but these applications still continue the traditional GUI button-based interaction methods and 3D modeling methods. Due to the limited screen resolution and calculation accuracy, the effi...
