Embodiment Construction

[0020] figure 1 It is a flow chart of the image rendering method provided by the embodiment of the present invention.

[0021] Such as figure 1 As shown, the process includes:

[0022] Step 101, determine the vertex illumination value of each pixel of the image to be rendered, and the angle between the illumination direction of each pixel and the normal direction of the vertex.

[0023] Among them, the vertex illumination value of each vertex can be calculated according to the formula I=Ambient+Diffuse*(LightDir·NormalDir), where I is the vertex illumination value, Ambient indicates the ambient illumination value, Diffuse indicates the diffuse illumination value, and * indicates multiplication , LightDir represents the light direction, NormalDir represents the normal direction of the vertex, (LightDir·NormalDir) is the point product of LightDir and NormalDir, the point product represents the angle between the light direction of the vertex and the normal direction of the vert...

Abstract

The invention discloses a method and device for rendering an image. The method comprises the following steps: determining a vertex lighting value of each pixel point of an image to be rendered, and an included angle between the lighting direction of each pixel point and the vertex normal direction; extracting a brightness template value of each pixel point from a preset lighting change template according to the value of the included angle between the lighting direction of each pixel point and the vertex normal direction; multiplying the difference, which is obtained by subtracting the vertex lighting value of each pixel point from the brightness template value of each pixel point, by a preset brightness adjustment coefficient, and then adding the vertex lighting value of the pixel point to obtain a final lighting value after the brightness is adjusted, and rendering the image according to the final lighting value. Through the method and the device for rendering the image, the image is more real, and the display effect is more three-dimensional.

Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to an image rendering method and device. Background technique [0002] With the development of digital processing equipment, games based on digital processing equipment have also been developed rapidly. Game software often involves a large number of image processing operations, for example, performing image rendering on characters and the like in the game screen. Image rendering often consumes a large amount of information processing resources, and mobile digital processing devices such as mobile phones have limited information processing resources. Therefore, it is necessary to save information processing resources as much as possible during image rendering. [0003] Currently, mobile digital processing devices generally perform image rendering through vertex lighting. specifically: [0004] The mobile digital processing device calculates the vertex lighti...
