Abstract

The invention discloses a method and a device for realizing a three-dimensional rotating interface based on the Android system. The method comprises the steps as follows: feature information of a to-be-realized three-dimensional interface of a target object is extracted, a three-dimensional coordinate system is selected according to the extracted three-dimensional interface feature information, and a mathematical model mapping the three-dimensional interface feature information is constructed; the target object is loaded to the mathematical model; the mathematical model on which texture mapping is performed is subjected to coordinate transformation, and an inclined mathematical model matched with the feature of the to-be-realized three-dimensional interface is acquired; the inclined mathematical model is triggered to rotate, so that a rotating mathematical model is obtained; the rotating mathematical model is subjected to perspective projection according to a preset viewpoint, so that sight plane coordinate information corresponding to the rotating mathematical model is obtained; and the sight plane coordinate information is converted into screen plane coordinate information, and the three-dimensional rotating interface is presented according to the converted screen plane coordinate information. With the application of the method and the device, the interface display effect can be improved, and the computational cost for realizing the three-dimensional rotating interface is reduced.

Problems solved by technology

Since the CPU needs to complete all data calculations required for coordinate information processing and coordinate rendering, a CPU with a higher main frequency is required to quickly complete data calculations, thereby greatly increasing the calculation cost for realizing a three-dimensional interface; further, through The two-dimensional display chip simulates the three-dimensional interface, and generally can only present the static interface effect based on three-dimensional, and the homogeneity of the interface is relatively serious, and the interface fluency and display effect are poor, making the user's experience of the three-dimensional interface poor; moreover, if It is necessary to realize a dynamic three-dimensional rotation interface, and it is necessary to construct image frames of the target object at different times, so that the amount of data calculation performed by the CPU is larger
