Abstract

The application provides a rendering method applied to electronic equipment, wherein the electronic equipment comprises a touch screen. The rendering method comprises the steps of obtaining the interaction state and the electric quantity of the electronic equipment, and determining a rendering mode corresponding to an object to be rendered according to the interaction state and the electric quantity. The method comprises the steps of enabling an object to be rendered through a high frame rate mode when the interaction state is that a sliding operation is carried out on a touch screen, and/or enabling electric quantity to exceed a first electric quantity threshold value, enabling the object to be rendered through a low frame rate mode when the static time of a display picture of the touch screen exceeds the first time threshold value, and/or enabling the electric quantity to not exceed a second electric quantity threshold value, enabling the first electric quantity threshold value to be larger than or equal to the second electric quantity threshold value, and enabling the number of vertexes of the low frame rate mode to be smaller than that of vertexes of the high frame rate mode. Therefore, different rendering modes are determined according to different interaction states and electric quantity of the electronic equipment, so that the power consumption of the electronic equipment can be reduced, and meanwhile, the calculated amount in the rendering process is reduced so as to improve the visual effect of rendering.

Background With the widespread popularity of electronic devices (such as smart wearable devices), users have put higher demands on the visual effect of their User Interfaces (UIs), such as displaying a dynamically rotated three-dimensional (3D) earth on a smart watch dial. However, electronic devices are limited by hardware configuration, and there is a significant bottleneck in rendering such 3D visual effects. For example, the operations required for 3D rendering, such as vertex transforms, illumination calculations, etc., exceed the operational capabilities of most electronic devices. For another example, the video memory bandwidth required by frequent full screen refreshing and texture reading is insufficient, so that the tearing of the picture and the system blocking are easy to be caused, and the visual experience is reduced.
