As used in the specification of this application and the appended claims, the singular forms "a", "an", "the", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
In this application, "at least one" means one or more, "a plurality" means two or more, "at least two" means two or three and three or more, "and/or" for describing an association relationship of associated objects, which means that there may be three relationships, for example, "a and/or B" may mean: only A, only B and both A and B are present, wherein A and B may be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. "at least one item(s) below" or similar expressions refer to any combination of these items. For example, at least one (one) of a, b, or c, may represent: a, b, c, "a and b," a and c, "" b and c, "or" a and b and c.
In order to describe the scheme of the present application more clearly, some knowledge related to the scheme is introduced below.
A Linux kernel: linux is an operating system kernel of an open-source computer. The operating system is a low-level supporting software that is used to interface with the hardware and provide a limited set of services for user programs. A computer system is a co-organism of hardware and software that are interdependent, not separable. The hardware of the computer comprises peripheral equipment, a processor, a memory, a hard disk and other electronic equipment which form a motor of the computer. But has no software to operate and control it and is not functional by itself. The software that performs this control task is called the operating system, which in Linux terminology is called the "kernel" and may also be called the "kernel". The main modules of the Linux kernel are divided into the following parts: storage management, CPU and process management, file systems, device management and drivers, network communications, and system initialization, system calls, etc.
Hardware resources: the most important hardware resources are computing resources and storage resources, and except for the management of computing resources and memory resources, the operating system manages other resources through input/output (IO). The display output interface belongs to output equipment, and hardware resources with the display function are acquired and managed by IO. And the hardware resources with the display function adjust 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 output the content in the display cache of the hardware resource to the display output interface, that is, 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: creating a corresponding two-dimensional texture class or a three-dimensional texture class according to the image resource, and obtaining the surface of the texture of the image resource; rendering a scene to the textured surface; rendering the texture itself, adding either 2D effects or 3D effects. For example, rotation of a sphere is realized, and a two-dimensional texture rendering mode or a three-dimensional texture rendering mode can be adopted; the two-dimensional texture rendering method comprises the following steps: the method comprises the steps of firstly, creating a two-dimensional texture class, loading two-dimensional image resources of a plurality of spheres into the two-dimensional texture class, and obtaining the surface of the texture of the two-dimensional image resources; secondly, rendering a scene to the surface of the texture, such as coloring and display parameter setting; and thirdly, rendering the texture, and playing the two-dimensional texture images in sequence to obtain the 3D effect of the rotary sphere. The steps of rendering by adopting the three-dimensional texture are as follows: the method comprises the steps of firstly, creating a three-dimensional texture class, loading a three-dimensional image resource into the three-dimensional texture class, and obtaining the surface of the texture of the three-dimensional image resource; secondly, rendering a scene to the surface of the texture, such as coloring and display parameter setting; and step three, rendering the texture, and controlling the rotation of the three-dimensional texture image to obtain the 3D effect of the rotary sphere.
