Background technique

There is usually a character equipment interface in the game, or a fashion interface in the mall to display the effect of character fashion. In order to make the character more three-dimensional, projection and lighting will be added to the character. The projection of the character to the ground will make the player feel that the character is stepping on the ground. The existing technologies in Unity include the following two schemes to add projection and lighting to the character: the first is to make the character produce projection through parallel light, and illuminate the character through additional light such as point light spotlight. The second is to use directional light to cast shadows and illuminate characters at the same time. However, since the two schemes use parallel light to generate projections, the first scheme will consider illuminating the character, which makes the angle setting of the parallel light unreasonable, which will lead to poor projection effects. The second scheme requires additional light to illuminate For the character, turning off the extra light in the low configuration mode of the device will cause the lighting to be abnormal.

Detailed ways

Embodiments of the present invention provide a virtual object display method, device, device, and storage medium to obtain light source information acting on a virtual object. The light source information includes parallel light data generated by a parallel light source perpendicular to the virtual object and parallel to the ground, and additional light data generated by an additional light source with a preset angle to the virtual object; use the parallel light data and the additional light data to adjust the brightness of the virtual object, and use the additional light data to generate the projection of the virtual object, and adjust the brightness Virtual objects and projections are displayed. The invention improves the accuracy of the lighting effect and the projection effect of the virtual object in various performance configurations.

It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments described herein can be practiced in sequences other than those illustrated or described herein. Furthermore, the term "comprising" or "having" and any variations thereof, are intended to cover a non-exclusive inclusion, for example, a process, method, system, product or device comprising a sequence of steps or elements is not necessarily limited to those explicitly listed instead, may include other steps or elements not explicitly listed or inherent to the process, method, product or apparatus.

For ease of understanding, the specific process of the embodiment of the present invention is described below, please refer to FIG. 1, an embodiment of the virtual object display method in the embodiment of the present invention includes:

101. Acquire light source information acting on a virtual object, the light source information includes parallel light data generated by a parallel light source perpendicular to the virtual object and parallel to the ground, and data generated by an additional light source at a preset angle to the virtual object Additional light data generated;

It can be understood that the subject of execution of the present invention may be a virtual object display device, and may also be a terminal or a server, which is not specifically limited here. The embodiment of the present invention is described by taking a terminal device as an execution subject as an example.

In this embodiment, the main light source that generates parallel light data is used as a parallel light source, and the additional light source that generates additional light data is used as an auxiliary light source. Since the frame rate will decrease on low-end mobile phones, high-configuration and low-configuration displays are provided. In the display mode of high configuration, the parallel light source and the additional light source will be turned on at the same time, and in the display mode of low configuration, only the parallel light source will be turned on. It should be noted that since tools such as Unity urp only support one parallel light source, the additional light source here is a non-parallel light source, such as a probe light source.

Specifically, as shown in Figure 2, the parallel light data acting on the virtual object, because the parallel light source is parallel to the ground and perpendicular to the virtual object, will not hit the light source on the ground, but will only be used to illuminate the virtual object. Shadows are produced, and virtual objects are not lit incorrectly due to the lack of extra light data in low configuration mode. The extra light data acting on the virtual object, because the extra light source and the virtual object are at a preset angle, such as 60° above, a better preset angle will allow the virtual object to project normally and will not be affected by the parallel light in the high-end mode The projection of the virtual object is elongated due to the influence of the illumination.

102. Use the parallel light data and the additional light data to adjust the brightness of the virtual object, and use the additional light data to generate a projection of the virtual object, and adjust the brightness of the virtual object and the projection to display.

In this embodiment, when calculating the projection of the virtual object on the ground, only the extra light source acting on the virtual object at a preset angle is used to emit light to generate pre-projected parallel light data; because the parallel light source is parallel to the ground, there is no A projection will be generated on the terrain, so there is no need to use parallel light data to calculate the projection. Here, by setting the angle of the parallel light data to distinguish the parallel light data from the extra light data used to generate the projection, it is to ensure that the projection is only related to the parallel light data when the display mode of the terminal device is switched between high and low. The information is only related to the extra light data, the resulting projections are not stretched.

In this embodiment, the parallel light data is used to illuminate the virtual object, and it can ensure that the virtual object is normally illuminated in the presence or absence of additional light data, that is, when the first display mode of the terminal device is switched between high and low , to ensure the normal display brightness of the virtual object.

In this embodiment, parallel light data and additional light data can be used to generate light maps and render them on the 2D or 3D model of the virtual object to adjust the brightness of the virtual object so that the virtual object appears illuminated. Then use the additional light data to generate a projection mask, render it at the projection position of the virtual object, and render the projection mask to the game scene, such as on the ground directly below the virtual object, or on the ground that deviates from the virtual object at a preset distance , mainly depends on the size of the preset angle of the additional light source, and the projection position is set according to the intersection position between the light source at the preset angle and the virtual object, and the intersection position with the ground. After the lightmap and projection mask are rendered, they can be displayed on the mobile terminal interface, including virtual objects and projections on the ground.

In the embodiment of the present invention, because the parallel light that illuminates the virtual object is parallel to the virtual object, a better lighting effect can be formed, and it is perpendicular to the ground, so no projection will be generated. Only additional light is used to generate projection by adjusting Proper angle and not affected by parallel light can produce correct shadow. Turning on the parallel light and the extra light at the same time under high configuration makes the projection and illumination of the character normal, and turning off the extra light under the low configuration mode can also illuminate the character correctly.

Referring to Fig. 3, another embodiment of the virtual object display method in the embodiment of the present invention includes:

201. Detect the display performance mode set for the virtual object;

202. When it is detected that the display performance mode set for the virtual object is a high configuration mode, control the parallel light source to emit light and the additional light source to emit light, and act on the virtual object;

203. When it is detected that the display performance mode set for the virtual object is a low configuration mode, control the parallel light source to emit light and act on the virtual object;

In this embodiment, in the high configuration mode, the additional light source is controlled to emit light to generate the projection of the virtual object, and the parallel light source is controlled to emit light to combine with the additional light source to illuminate the virtual object; in the low configuration mode, in the second mode, in order to reduce consumption, it will only control parallel light sources to illuminate virtual objects, and will not produce projections.

204. Obtain light source information acting on the virtual object, the light source information includes parallel light data generated by a parallel light source perpendicular to the virtual object and parallel to the ground, and data generated by an additional light source at a preset angle to the virtual object Additional light data generated;

205. Use the additional light data to adjust the attribute parameters of the projection sheet, and generate a projection of the virtual object based on the projection sheet after adjusting the attribute parameters;

In this embodiment, a projection sheet is set at the projection position of the virtual object, which is specially used to accept the projection of the virtual object and display it, so as to prevent the parallel light source from reflecting or illuminating the ground in other ways to affect the projection generation, and the projection sheet is directly superimposed There is no need to deal with the seam problem on the background, and it can better simulate the effect of the virtual object standing in the scene (directly forming a projection on the ground will easily cause seams on the connection between the ground surface and the background board); at the same time, write a new projection function, Used only to calculate extra light data, not directional light data, so that projections generated and displayed on slides are only associated with extra light data. The isolation of additional light data and parallel light data can also be achieved by transparencies.

Specifically, in 3D software such as Unity and UE4, a new Shader (shader) can be written for the projection film, and the translucent mixing mode of the new Shader can be set at the same time to be used for mixing the projection of additional light data on the Shader . According to the extra light data, change the properties parameters of the slide, such as color and transparency, display the projection area of the extra light data on the slide, generate a projection style, and make other areas of the slide transparent to hide other areas.

In one embodiment, the adjusting the attribute parameters of the projection sheet by using the additional light data includes: the blending mode of the projection sheet is a translucent blending mode, and the initial attribute of the projection sheet is set to a transparent attribute ; According to the preset angle corresponding to the additional light data, using a preset projection function, calculate the projection pixel where the additional light data is located on the projection sheet; adjust the projection pixel on the projection pixel according to the additional light data The color value and transparency of the .

In one embodiment, the adjusting the color value and transparency of the projected pixel according to the additional light data includes: judging the amount of light acting on the virtual object at a preset angle according to the additional light data Whether it is greater than a preset amount; if the amount of illumination is greater than a preset amount, calculate the first color value and first transparency on the projected pixel according to the additional light data; if the amount of illumination is not greater than a preset amount , the projected pixels are adjusted to a preset second color value and a preset second transparency.

In this embodiment, taking Unity as an example, you can directly set the Shader RenderType of the Shader to Transparent in the Shader written for the slideshow, that is, set the rendering mode to be fully transparent Shader: Tags{"RenderType"="Transparent"" Queue"="Transparent" "RenderPipeline"="LightweightPipeline" "IgnoreProjector"="True"}. Then by setting the Shader to BlendSrcAlpha OneMinusSrcAlpha, that is, the traditional semi-transparent blending method, it can be used to blend the light source data of the high-end mode.

Specifically, by writing a new projection function PixelAdditionalShadow, the parallel light data is not calculated in the projection function. When checking whether the illumination amount of the additional light data is greater than the preset amount, for example, if the preset amount is 0, then judge whether the illumination amount is greater than 0, and return 0 directly if it is not greater than 0: UNITY_BRANCH; if(_AdditionalLightsCount.x<=0) ;return 0;, at this time, you can preset the corresponding second color value to any value or not change the color value of the slide, and then preset the corresponding second transparency to 100%, that is, hide the slide so that the virtual object does not projection.

Specifically, iterate through all the extra light data, determine the projection pixel where the light source data is located on the slide, and then overlay the projection of the extra light data. You can control the color and transparency of the projected pixel by adding the parameter _BaseColor: Light light=(Light )0; ForEachAdditionalLight(light); {shadow+=light.shadowAttenuation;}; return shadow*_BaseColor.

In one embodiment, if the initial attribute of the projected sheet is set to be non-transparent, after adjusting the color value and transparency of the projected pixel according to the additional light data, further comprising: obtaining the other non-projected pixels in the projection sheet except the projected pixels, and adjust the property of the non-projected pixels from non-transparent to transparent, so as to hide the area where the non-projected pixels are located.

As mentioned above, if the blending mode of the slideshow is translucent, and the slideshow attribute is transparent; the non-projected pixels in the slideshow will not display projection, and the slideshow attribute parameter is a transparent parameter, that is, the transparency is 1. The slideshow is already hidden and invisible, so there is no need to perform any operations on the slideshow. If the initial setting of the slide attribute parameter is a non-transparent parameter, then the transparency of the non-projected pixels of the slide is less than 1 at this time, and it is visible by default on the interface of the terminal device, then the attribute parameter of the non-projected pixel needs to be set to Adjust the non-transparent parameter to the transparent parameter, that is, adjust the transparency of the non-projected pixel to 1, so that the non-projected pixel can be hidden.

206. Using the parallel light data and the additional light data, calculate the lighting information on the surface of the virtual object, and determine the shadow shading relationship existing in each area of the surface of the virtual object;

207. Based on the illumination information and the shadow-shading relationship, adjust the brightness on the surface of the virtual object, and use the additional light data to generate a projection of the virtual object, and adjust the brightness of the virtual object and the virtual object projection to display.

In this embodiment, in the high-low configuration display mode of the terminal device, the virtual object will be illuminated to make the display of the virtual object more natural, real and clear, that is, the light source information includes at least parallel light data. Here, the brightness information on the virtual object is first calculated based on the parallel light data to adjust the brightness of the virtual object surface. The display of the virtual object under the parallel light will be more natural and real. Therefore, it is preferable to adjust the parallel light brightness of the virtual object here. .

Specifically, parallel light projection of parallel light data can be enabled, and parallel light projection can be used to look up at the character in the character interface. Parallel light projection will not be projected on the ground, but only on the virtual object, providing shadow and shading relationships between each part of the virtual object. , For example, the face is covered by hair, the limbs are covered by clothing, etc., and shadows are generated in the covered parts. In this way, in the low configuration mode of the terminal device, when the extra light data is turned off, the virtual object can still be uniformly illuminated.

In the embodiment of the present invention, because the parallel light that illuminates the virtual object is parallel to the virtual object, a better lighting effect can be formed, and it is perpendicular to the ground, so no projection will be generated. Only additional light is used to generate projection by adjusting Proper angle and not affected by parallel light can produce correct shadow. Turning on the parallel light and the extra light at the same time under high configuration makes the projection and illumination of the character normal, and turning off the extra light under the low configuration mode can also illuminate the character correctly.
