Abstract

The invention relates to a three-dimensional graph rotating operation method. The method comprises the following steps: extracting feature information of the three-dimensional graph, and determining avisual plane according to the extracted feature information; receiving a touch operation of a user for the three-dimensional graph on the mobile terminal; acquiring a physical attribute and an analogattribute of the touch screen of the mobile terminal corresponding to the touch operation; determining an analog angular displacement of the touch operation according to the physical attribute and the analog attribute; according to a preset mapping proportion of the analog angular displacement and the three-dimensional graph, obtaining operation parameters of the three-dimensional graph relativeto a visual plane corresponding to the touch operation; and according to the operation parameters, realizing the operation action of the three-dimensional graph. Not only can the random rotation of the 3D graph be realized, but also the operation mode, operation feedback and the like are more in line with the habit of observing and operating the 3D graph by people, and are more realistic. The invention also relates to a mobile terminal.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a three-dimensional graphic rotation operation method and a mobile terminal. Background technique [0002] 3D image technology has been widely used in people's life and production. Among them, in entertainment, manufacturing, visual communication, etc., a large number of 3D image technologies are used to improve the expressiveness of the picture and make it more realistic. At the same time, 3D image technology is not limited to visual presentation, and the accompanying interaction has also become a popular direction of continuous research and exploration. At present, mainstream display devices (such as mobile phones, tablet computers, etc.) are still based on 2D screens. Although the screen can produce a more realistic 3D visual effect, due to device limitations, 3D display can only be realized through gesture interaction on the 2D screen. graphics to operate. ...
