Control method and system for displaying 3D interface on touch equipment

Abstract

The invention relates to the field of graphical user interfaces, in particular to a control method and system for displaying a 3D interface on touch equipment. The method for displaying the 3D interface on the touch equipment includes: under a preset mode, acquiring coordinate point taking operation and gesture operation matched with external operation; acquiring a moving operation and 3D displayimage matched first observation point according to the coordinate point taking operation; according to the gesture operation, taking the first observation point as a datum point to form a control order matched with the gesture operation; adjusting a 3D display image according to the control order. By matching of the gesture operation to form a touch point and capturing of the matched display image, switching or adjusted displaying of the datum point on 3D display images at any positions is realized, and displaying of a 3D interface on a screen is switched directly and flexibly. As for a user,simplicity and freeness in operation are achieved, great visual effects are realized, and user experience is improved.

[0002] A 3D map is a special plan view, through the overlap and separation of the visual imaging system of the eyes, the hidden image in the picture can be seen. With the development of display technology, mobile terminals can already display 3D maps with three-dimensional effects. However, the inventor found that the existing mobile terminals can only display 3D pictures, and there is no corresponding solution in the prior art to realize the conversion and display of the 3D interface at any viewing angle. , when the interface display is switched by touch movement on the touch screen of the touch device, it only involves displacement in two directions, that is, the horizontal direction of the screen (represented by x direction below) and the vertical direction (represented by y direction below) Direction representation), so the operation of switching the interface display or switching from one application object to another application object on the interface is generally a translation operation

The 3D interface displayed on the touch device usually displays the scene observed by the observation point in the 3D space and the application objects set in the scene, wherein the observation point can also be called a camera device or a camera in 3D graphics. Eyes, because the existing 3D interface display uses the method of 2D interface display, the interface display can only be switched through translation operations, and if the focus of the observation point is to be switched from one application object on the interface to another application object, It can also only perform translation operations. In other words, the existing technology can only realize viewing angle display switching and application object switching in one or two directions. The focus of the observation point can be understood as the focus of the lens in the camera device or the focus point of the eyes.

However, due to the different spatial positions of the observation points, the observed scenes are different; the observation angles of the observation points are different, and the observed scenes are also different, and the application object can be set at any position in the spatial scene, so only one or two It is difficult to meet the display requirements of 3D interface by viewing angle display switching of direction and application object switching
