The embodiment of the application provides a method, a system, equipment and a storage medium for displaying a startup interface, and in order to more clearly describe the scheme of the application, the following describes some knowledge related to the scheme.

Linux kernel: linux is an open source computer operating system kernel. The operating system is low-level supporting software that interfaces with the hardware and provides a limited set of services for the user program. A computer system is a symbiont of hardware and software that is interdependent and indivisible. The hardware of the computer comprises peripheral devices, a processor, a memory, a hard disk and other electronic devices which form the engine of the computer. But without software to operate and control it, is not working on its own. The software that performs this control work is called the operating system, which in Linux terminology is called the "kernel" and may also be called the "core". The main modules of the Linux kernel are divided into the following parts: storage management, CPU and process management, file system, device management and driving, network communication, initialization of the system, system call, etc.

Hardware resources: the most dominant of the hardware resources are computing resources and storage resources, and the operating system manages other resources through input/output (IO) in addition to the management of computing resources and memory resources. The display output interface belongs to output equipment, and obtains hardware resources with display function to be managed by IO. And the hardware resources with the display function are used for adjusting the display sequence of the hardware resources in the display output interface by setting the display sequence value of the hardware resources. The hardware resource with the display function can provide a hardware channel for the cache content, and the content in the display cache of the hardware resource is output to the display output interface, namely, writing data in a specific format into the display cache means outputting the content to the display output interface.

Texture rendering: the texture rendering comprises two-dimensional texture rendering and three-dimensional texture rendering, and the texture rendering process comprises the following steps of: creating a corresponding two-dimensional texture class or three-dimensional texture class according to an image resource, and obtaining the surface of the texture of the image resource; rendering the scene to the textured surface; rendering the texture itself, adding a 2D effect or a 3D effect. For example, a sphere is rotated, and a two-dimensional texture rendering mode or a three-dimensional texture rendering mode can be adopted; the steps of adopting two-dimensional texture rendering are as follows: firstly, creating a two-dimensional texture class, and loading two-dimensional image resources of a plurality of spheres into the two-dimensional texture class to obtain the surface of the texture of the two-dimensional image resources; second, rendering the scene to the textured surface, e.g., shading, display parameter settings; and thirdly, rendering the textures, and sequentially playing the two-dimensional texture images to obtain the 3D effect of the rotary sphere. The three-dimensional texture rendering method comprises the following steps: firstly, creating a three-dimensional texture class, and loading a three-dimensional image resource into the three-dimensional texture class to obtain the surface of the texture of the three-dimensional image resource; second, rendering the scene to the textured surface, e.g., shading, display parameter settings; and thirdly, rendering the texture, controlling the rotation of the three-dimensional texture image, and obtaining the 3D effect of the rotary sphere.
