Problems solved by technology

This kind of calculation usually makes the display effect of the skin area softer and more transparent, close to the real texture. However, this kind of calculation usually also blurs the texture details of the skin surface, resulting in unclear display of details such as spots on the skin surface and reducing the picture quality.

Embodiment 1

[0040] figure 1 A flowchart showing a rendering method according to an embodiment of the present invention. Such as figure 1 As shown, the method is used for rendering the skin area in the 3D game display screen, and the method mainly includes:

[0041] Step 101, determine the skin area in the display screen to be rendered;

[0042] Step 102, according to the setting of the light source, establish first lighting information for the skin area without mapping;

[0043] Step 103, performing subsurface scattering calculation on the first illumination information to obtain second illumination information;

[0044] Step 104, applying the second lighting information to the texture map of the skin area, so as to realize the rendering of the skin area.

[0045] The process of constructing a 3D image usually includes modeling, mapping, rendering and other links. Modeling usually refers to the process of constructing a geometric structure model of an object. Mapping usually refers t...

Embodiment 2

[0062] Figure 4 A flow chart of a rendering method according to another embodiment of the present invention is shown. Wherein, steps 402-405 are similar to steps 101-104 in Embodiment 1, and will not be described again here. On the basis of Embodiment 1, the method of this embodiment further includes step 401, setting a first auxiliary light source, and the irradiation direction of the first auxiliary light source is consistent with the shooting direction of the player's perspective camera.

[0063] In the prior art, only the main sun is used as the light source for lighting the characters in 3D role-playing games. However, when the characters are in shadow or backlight state, the display effect of the characters is usually not good because of insufficient light.

[0064] For this reason, this embodiment further sets a first auxiliary light source whose illumination direction is consistent with the shooting direction of the player’s perspective camera for such an application...

Embodiment 3

[0073] Figure 7 A block diagram of a rendering device according to an embodiment of the present invention is shown. Such as Figure 7As shown, the rendering device 700 is used to render the skin area in the three-dimensional game display screen, and the device mainly includes: a determining component 701, which is used to determine the skin area in the display screen to be rendered; The setting of the light source is to establish the first lighting information for the unmapped skin area; the calculation component 703 is used to perform subsurface scattering calculation on the first lighting information to obtain the second lighting information; and the application component 704 is used to Applying the second lighting information to the texture of the skin area, so as to realize the rendering of the skin area.

[0074] In this embodiment, the texture information in the map does not participate in the subsurface scattering calculation, and texture details will not be blurred,...

Abstract

The invention relates to a rendering method and device, and the method and device are used for the rendering of a skin region in a three-dimensional game display frame. The rendering method comprises the steps: determining a skin region in a to-be-rendered frame; building first illumination information for an unmapped skin region according to the setting of a light source; carrying out the subsurface scattering calculating of the first illumination information, and obtaining second illumination information; and applying the second illumination information to a map of the skin region, so as to achieve the rendering of the skin region.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a rendering method and device. Background technique [0002] In the process of rendering the skin area in the 3D game display screen, in order to pursue realistic and realistic effects, the phenomenon of subsurface scattering is usually considered. [0003] Subsurface scattering, referred to as 3S (Subsurface scattering), is a light transmission process in which light enters an object of non-metallic light-transmitting material such as skin and scatters inside, and then exits through other vertices on the surface of the object. [0004] In order to express this subsurface scattering phenomenon, the current traditional method is to perform subsurface scattering calculation for the skin area in the display screen during the rendering process. This kind of calculation usually makes the display effect of the skin area softer and more transparent, close to the real texture. Ho...
