[0002] Global illumination is used to simulate the lighting interaction between geometry and material surfaces, adding realistic lighting effects to scenes and projects. Currently, many games need to present the light and shadow transformation effects of day and night. Usually, real-time lighting methods can be used to simulate the activity of light to achieve the lighting effects of day and night transformations.

[0003] However, the real-time lighting method requires real-time calculation of lighting information, which has a high computational overhead. Another way to simulate the activity of light is to pre-calculate the lighting information, that is, bake it, and store this lighting information as a light map. By pre-calculating in advance, the computational overhead in real-time operation can be reduced. However, this method usually bakes all lighting information into the light map, making it difficult to change the data of the light map, and thus it is difficult to use the light map to achieve the lighting effect of day and night change.

[0036] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0037] Embodiments of the present application provide a light processing method, device, electronic device, and storage medium.

[0038] The light processing device can be integrated into an electronic device, which can be a terminal, a server, or other devices. The terminal can be a mobile phone, a tablet computer, a smart Bluetooth device, a laptop, or a personal computer (PC), etc. The server can be a single server or a server cluster composed of multiple servers.

[0039] In some embodiments, the illumination processing device may also be integrated into multiple electronic devices. For example, the illumination processing device may be integrated into multiple servers, and the illumination processing method of the present application may be implemented by multiple servers.

[0040] In some embodiments, the server may also be implemented in the form of a terminal.

[0041] For example, refer to Figure 1, shows a scene schematic diagram of the illumination processing method provided by an embodiment of the present application, and the scene may include at least one terminal 1000, at least one server 2000, at least one database 3000, and a network 4000. The terminal 1000 held by the user can be connected to the server 2000 through the network 4000. Among them, the terminal 1000 is any device with computing hardware that can support and execute software products corresponding to the game; the server 2000 can be a single server or a server cluster; the network 4000 can be a wireless network or a wired network, such as a wireless network such as a wireless local area network (WLAN), a local area network (LAN), a cellular network, a 2G network, a 3G network, a 4G network, a 5G network, etc. In addition, different terminals 1000 can also use their own Bluetooth network or hotspot network to connect to other terminals or to the server 2000. In addition, the system may also include at least one database 3000, which is used to store game data generated when the user uses the terminal 1000.

[0042] Among them, an application can be installed on the terminal 1000. When the application is run on the terminal 1000, the game scene provided by the application can achieve the effect of day and night change. Specifically, it can be to obtain the lighting data to be processed on the terminal 1000, wherein the lighting data to be processed includes point light data and indirect light data; bake the point light data to obtain the first lighting information corresponding to the point light data, and the first lighting information includes a color value and an intensity value; bake the indirect light data to obtain the second lighting information corresponding to the indirect light data, and the second lighting information includes an intensity value; generate a lighting map according to the first lighting information and the second lighting information. When the application is run on the terminal 1000, the picture can be rendered according to the lighting map to achieve the lighting change effect.

[0043] In some embodiments, the generation of the light map can be performed in the server 2000. The server 2000 can provide an application download service, encapsulate the light map in the application installation package, and store the light map in the terminal 1000 when the application is installed on the terminal 1000. Therefore, when the application is run on the terminal 1000, the light map can be used for real-time rendering of the picture to achieve a day and night change effect in the game scene.

[0044] The following are detailed descriptions of each.

[0045] In this embodiment, a light processing method is provided, such as Figure 2 As shown, the specific process of the illumination processing method can be as follows:

[0046] S110, obtaining illumination data to be processed, wherein the illumination data includes point light data and indirect light data.

[0047] The illumination data to be processed refers to the illumination data that needs to be pre-calculated. Global illumination can include direct illumination and indirect illumination. Direct illumination refers to the illumination that hits the surface of an object for the first time, and indirect illumination refers to the illumination obtained by bounce. Usually, indirect illumination is obtained through multiple bounces and illumination superposition. In order to reduce the amount of calculation during image rendering, indirect illumination can be pre-calculated and stored in the light map.

[0048] In game engines, three types of light sources are usually provided, namely point light, sky light and parallel light. Point light is an idealized point light source, similar to an artificial light bulb; sky light refers to the use of objects such as the atmosphere, clouds, and mountains as illumination to simulate global brightness, such as the brightness of a dark surface; parallel light, also known as directional light or directional light, refers to parallel light without attenuation, similar to sunlight. Each light source can set its mobility type. The mobility types provided in the game engine include fixed light sources. Fixed light sources refer to light sources whose positions remain fixed during runtime, but whose colors and brightness can be modified, creating possibilities for the entire day and night transformation effect.

[0049] In order to achieve the effect of day and night changes in the game scene, it is necessary to flexibly split and bake the data that changes with the time dimension, such as the direction, color, brightness, etc. of the light, and record them in the light map.

[0050] Among them, point lights can refer to artificial light sources such as lanterns and lights in the scene. These artificial light sources are usually turned off during the day and turned on at night, so they have switching logic. In order to obtain the effect of day and night change, the point lights need to record the on and off states, that is, the color and intensity of the point lights during the day, as well as the point lights and colors at night, need to be recorded.

[0051] Similarly, since the direction of the main light changes with time, the color, bounce, and propagation of the parallel light also change with time. In order to obtain more scientific results, you can choose to bake these lights that change in the time dimension separately. Therefore, the lighting data to be processed can include point light data and indirect light data.

[0052] The point light data may include first point light data and second point light data, the first point light data is used to represent point light during the day, and the second point light data is used to represent point light at night. The indirect light data may include first indirect light data and second indirect light data, wherein the first indirect light data refers to light data obtained by bouncing and superimposing parallel light, and the second indirect light data refers to light data obtained by bouncing and superimposing skylight.

[0053] S120: Bake the point light data to obtain first lighting information corresponding to the point light data, where the first lighting information includes a color value and an intensity value.

[0054] After obtaining the point light data, the point light data may be baked to obtain first lighting information corresponding to the point light data. Baking refers to pre-calculating the point light data in advance to calculate the lighting effect generated by the point light data, i.e., the first lighting information. The first lighting information may represent the color corresponding to the lighting effect generated by the point light data and the intensity information of the lighting, i.e., the first lighting information may include a color value and an intensity value.

[0055] In some embodiments, in order to achieve the effect of day and night conversion, it is necessary to obtain the lighting effect during the day and the lighting effect at night. Since the point light data may include first point light data and second point light data, wherein the first point light data represents the point light during the day and the second point light data represents the point light at night, the first point light data and the second point light data may be baked respectively to obtain corresponding baking results. Therefore, when the point light data is baked to obtain the first lighting information, the first point light data may be baked to obtain the first color value and the first intensity value corresponding to the first point light data; the second point light data may be baked to obtain the second color value, the second intensity value and the point light direction corresponding to the second point light data; and the first color value, the first intensity value, the second color value, the second intensity value and the point light direction are determined as the first lighting information.

[0056] Usually, after baking the lighting, you can get the color value, intensity value and direction information. If all the above information needs to be saved for each baking result, the memory and package size of the lighting map will be larger. In order to reduce the memory of the final lighting map, you can selectively retain a part of the data for storage, which is convenient for running on devices with poor hardware configuration and reducing the requirements of the day and night effect on the hardware configuration of the device.

[0057] Since the first point light data refers to the point light during the day, and the point light direction during the day is usually dominated by skylight, when there is only the first point light data, the corresponding lighting effect can be calculated based on the first point light data, and the color value and intensity value used to express the lighting effect can be used as the corresponding baking result. That is, after the first point light data is baked, the first color value and the first intensity value obtained by the baking process can be stored to obtain the baking result corresponding to the first point light data, so that the lighting effect during the day can be obtained.

[0058] When there is only the second point light data, the corresponding lighting effect can be calculated according to the second point light data, and the color value, intensity value and point light direction used to express the lighting effect are used as the baking result corresponding to the second point light data. That is, after the second point light data is baked, the second color value, second intensity value and point light direction obtained by the baking process can be stored to obtain the baking result corresponding to the second point light data, so as to obtain the lighting effect at night.

[0059] From the above, it can be seen that the first lighting information may include a first color value, a first intensity value, a second color value, a second intensity value and a point light direction, wherein the first color value and the first intensity value are the lighting effects corresponding to the point light during the day, and the second color value and the second intensity value are the lighting effects corresponding to the point light at night with the point light direction.

[0060] S130. Bake the indirect light data to obtain second lighting information corresponding to the indirect light data, where the second lighting information includes an intensity value.

[0061] After obtaining the indirect light data, the indirect light data may be baked to obtain second lighting information corresponding to the indirect light data. The baking process refers to precalculating the indirect light data in advance to calculate the lighting effect generated by the indirect light data, i.e., the second lighting information. The second lighting information may represent intensity information corresponding to the lighting effect generated by the indirect light data, i.e., the second lighting information may include an intensity value.

[0062] In some embodiments, the indirect light data may include first indirect light data and second indirect light data, wherein the first indirect light data is indirect light data of parallel light, and the second indirect light data is indirect light data of skylight. When the indirect light data is baked to obtain the second illumination information, the first indirect light data and the second indirect light data may be baked separately, and the corresponding baking results may be used as the second illumination information. In some embodiments, when the first indirect light data and the second indirect light data are baked separately to obtain the second illumination information, the first indirect light data may be baked to obtain parallel light indirect light information corresponding to the first indirect light data; the second indirect light data may be baked to obtain skylight indirect light information corresponding to the second indirect light data; and the parallel light indirect light information and the skylight indirect light information may be determined as the second illumination information.

[0063] Among them, parallel light is used to simulate sunlight in the scene. In 24 hours a day, the direction of parallel light is different at different times. Usually, in order to obtain a more realistic lighting effect, the parallel light of each hour can be baked. However, in order to take into account the performance of the device, the parallel light of several key hours can be baked. Therefore, in some embodiments, the first indirect light data includes first indirect light data of different directions. When baking the first indirect light data, the first indirect light data of each direction can be baked separately to obtain the parallel light color value corresponding to the first indirect light data of each direction; according to the preset conversion rule, each of the parallel light color values ​​is converted into a parallel light intensity value; the parallel light intensity value corresponding to the first indirect light data of each direction is determined as the parallel light indirect light information.

[0064] Parallel light is used to simulate sunlight, and the direction of the parallel light of sunlight at sunrise and sunset is different. In order to improve the realism of the lighting effect, you can also obtain the first indirect light data corresponding to the middle time between sunrise and sunset. For example, if the sunrise time is 8 o'clock and the sunset time is 18 o'clock, you can choose 12 o'clock as the middle time, that is, the first indirect light in different directions can refer to the parallel light corresponding to 8 o'clock, 12 o'clock, and 18 o'clock.

[0065] In some implementations, in order to improve the realism of the lighting effect, the parallel light corresponding to each moment may be obtained, and the parallel light corresponding to each moment may be baked to obtain the corresponding parallel light indirect light information.

[0066] After obtaining the first indirect light data in different directions, the first indirect light data in each direction can be baked respectively to obtain the parallel light color value corresponding to the first indirect light data in each direction. That is, the number of baking times is the same as the number of first indirect light data in different directions. If there are first indirect light data in three directions, bake three times to obtain the parallel light color values ​​corresponding to the three directions. For example, the three directions are direction A, direction B, and direction C. After three bakings, the parallel light color value a corresponding to direction A, the parallel light color value b corresponding to direction B, and the parallel light color value c corresponding to direction C can be obtained.

[0067] After obtaining the parallel light color value corresponding to the parallel light in each direction, in order to further reduce the memory size occupied by the illumination map, the parallel light color value can be converted into a parallel light intensity value. Specifically, the parallel light color value can be converted into a parallel light intensity value according to a preset conversion rule, so as to obtain the parallel light intensity value corresponding to the first indirect light data in each direction, and all parallel light intensity values ​​constitute the parallel light indirect light information.

[0068] When baking the second indirect light data to obtain the skylight indirect light information, the second indirect light data can be baked to obtain the skylight color value and skylight shielding data corresponding to the second indirect light data, the skylight shielding data including the skylight shielding direction and the skylight shielding intensity value; according to a preset conversion rule, the skylight color value is converted into the skylight intensity value; the skylight intensity value, the skylight shielding direction and the skylight shielding intensity value are determined as the skylight indirect light information.

[0069] After baking the second indirect light, the skylight color value and skylight occlusion data in the baking result may be retained. The skylight occlusion data may include a skylight occlusion direction and a skylight occlusion intensity value. After obtaining the skylight color value, in order to further reduce the memory size occupied by the light map and facilitate running on devices with low hardware configurations such as mobile devices, the skylight color value may be converted into a skylight intensity value according to a preset conversion rule.

[0070] The preset conversion rule may be a preset mapping relationship between color values ​​and intensity values. The color value is usually described in RGB color space, with data of R channel, G channel and B channel respectively, and the intensity value channel is a single channel. Therefore, converting the color value to the intensity value is to convert the three channels into a single channel. Specifically, the preset conversion rule may be to normalize the color value to obtain a normalized result, perform a dot product of the normalized result and the color value, and divide the result by the length of the color value to obtain the intensity value.

[0071] It can be known from the above content that the second illumination information may include parallel light intensity value, sky light intensity value, sky light shielding direction and sky light shielding intensity value. There may be multiple parallel light intensity values, i.e., multiple parallel light intensity values ​​obtained by baking the first indirect light data in multiple different directions, the sky light intensity value is obtained by baking the second indirect light data, and the sky light shielding direction and the sky light shielding intensity value are the default results obtained by the game engine when baking the second indirect light data.

[0072] S140: Generate a lighting map according to the first lighting information and the second lighting information.

[0073] After obtaining the first illumination information and the second illumination information, a illumination map may be generated using the first illumination information and the second illumination information. An illumination map is also called a light map, which refers to a map that stores effect data calculated in advance for the effect of illumination on a model, wherein the illumination map may refer to a single light map or may be composed of multiple light maps.

[0074] After obtaining the first illumination information and the second illumination information, in order to generate an illumination map, it is usually necessary to store the first illumination information and the second illumination information at corresponding positions in the illumination map, so as to obtain an illumination map including the first illumination information and the second illumination information.

[0075] In some implementations, the first lighting information and the second lighting information may be stored as a light map.

[0076] In some implementations, the first lighting information and the second lighting information may be stored as a plurality of light maps.

[0077] As an implementation method, the first lighting information includes a first color value, a first intensity value, a second color value, a second intensity value, and a point light direction, and the second lighting information includes a parallel light intensity value, a sky light intensity value, a sky light shading direction, and a sky light shading intensity value. When generating a lighting map, the first color value, the first intensity value, the second color value, the second intensity value, the point light direction, the parallel light intensity value, and the sky light intensity value may be stored as a first light map; the sky light shading direction and the sky light shading intensity value may be stored as a second light map; and the lighting map may be generated based on the first light map and the second light map.

[0078] That is, the skylight intensity values ​​in the first lighting information and the second lighting information are stored in the same light map, and the skylight shading direction and the skylight shading intensity value in the second lighting information are stored in another light map.

[0079] When storing the skylight intensity values ​​in the first lighting information and the second lighting information as the first light map, in order to ensure that the memory occupied by the first light map is not too large, the specific storage method can be: storing the first color value and the first intensity value as a first color space; storing the second color value and the second intensity value as a second color space; storing the point light direction as a third color space; storing the parallel light intensity value and the skylight intensity value as a fourth color space; and obtaining the first light map according to the first color space, the second color space, the third color space and the fourth color space.

[0080] Each color space includes four channels, namely R channel, G channel, B channel and Alpha channel. Figure 3 , shows a schematic diagram of the storage of various data in the first light map. Figure 3Each grid in represents an RGBA, and the first color value and the first intensity value are stored as the first color space, that is, the first color value occupies the three RGB channels, and the first intensity value occupies the Alpha channel. The second color value and the second intensity value are stored as the second color space, that is, the second color value occupies the three RGB channels, and the second intensity value occupies the Alpha channel. The point light direction is stored in the third color space, that is, the point light direction occupies the three RGB channels, and there is no data in the Alpha channel. The parallel light intensity value and the skylight intensity value are stored in the fourth color space, that is, the four RGBA channels are all intensity values. It can be seen from this that the first light paste Figure 1 A total of 4 RGBA are occupied.

[0081] The skylight occlusion direction and the skylight occlusion intensity value in the second lighting information are stored in the second light map. The skylight occlusion direction occupies three RBG channels, and the skylight occlusion intensity value occupies the Alpha channel.

[0082] The first light map and the second light map together constitute a light map. In some embodiments, after the light map is generated, the light map can be used to render the picture.

[0083] When using the illumination map for rendering, the current parallel light color value and the current sky light color value can be obtained; the current parallel light color value is multiplied by the parallel light intensity value to obtain the parallel light indirect light information; the current sky light color value is multiplied by the sky light intensity value to obtain the sky light indirect light information; based on the parallel light indirect light information, the sky light indirect light information, the first illumination information, the sky light shielding direction and the sky light shielding intensity value, the current illumination information is calculated; and the image is rendered based on the current illumination information. For example, you can refer to Figure 4 , showing a schematic diagram of restoring parallel light indirect light, Figure 4 According to the baking method of the embodiment of the present application, the parallel light intensity can be obtained, and the parallel light intensity is used to replace the original baking result. The parallel light intensity is multiplied by the current parallel light color to obtain the current parallel light indirect light.

[0084] When rendering a picture based on the illumination map, the current parallel light color value and the current sky light color value can be obtained, which refer to the parallel light color value and the sky light color value obtained at the current moment. The parallel light information included in the second illumination information can be the parallel light intensity values ​​corresponding to three hours, and the parallel light intensity value corresponding to the three hours can be interpolated to obtain the parallel light intensity value corresponding to the current moment.

[0085] By multiplying the parallel light intensity value corresponding to the current moment with the current parallel light color value, the parallel light indirect lighting effect corresponding to the current moment can be restored. Similarly, by multiplying the skylight intensity value obtained from the first lightmap with the current skylight color value corresponding to the current moment, the skylight indirect lighting effect corresponding to the current moment can be restored.

[0086] Finally, based on the parallel light indirect light information, the skylight indirect light information, the first lighting information, the skylight shading direction and the skylight shading intensity value, the current lighting information is calculated, and rendering is performed based on the current lighting information to obtain the final day and night transformation effect.

[0087] Through the lighting processing method provided in the embodiment of the present application, the point light data and the indirect light data are baked separately to obtain the first lighting information corresponding to the point light data and the second lighting information corresponding to the indirect light data, and a lighting map is generated based on the first lighting information and the second lighting information, so that the image can be rendered based on the lighting map later. By baking the point light data and the indirect light data separately, the elements that change with time in the day and night transformation can be split and baked separately, which is convenient for subsequent real-time calculation according to the corresponding baking results to restore a more realistic day and night transformation effect. And the split baking method makes the amount of data baked each time smaller, which can reduce the requirements for computing power and save computing power.

[0088] In addition, in the embodiment of the present application, parallel light in different directions corresponding to three hours are baked respectively, and three sets of parallel light indirect light information can be obtained. The current mainstream baking is to bake all the information together, and the obtained parallel light indirect light information is also one hour. When the picture is rendered, the parallel light indirect light information cannot match most of the hours, resulting in poor results. In this application, in order to take into account the performance of the device and the effect of day and night change, the parallel light indirect light information of three hours is used. When the picture is rendered, the accurate parallel light indirect light information corresponding to each hour can be obtained by interpolation, which can not only improve the effect of day and night change and present a more realistic picture, but also run on devices with lower configurations.

[0089] The method described in the above embodiment will be further described in detail below.

[0090] In this embodiment, a Massive Multiplayer Online Game (MMOG) is taken as an example. In such games, it is usually necessary to implement day and night changes, that is, the game scene needs to simulate the light and shadow effects of the day and night changes in the real environment to enhance the authenticity of the game scene. The following takes the first point light data as daytime point light data, the second point light data as nighttime point light data, the first indirect light data as parallel light indirect light data in three directions, and the second indirect light as skylight indirect light data as an example to describe the method of the embodiment of the present application in detail.

[0091] like Figure 5 As shown, the specific process of a lighting processing method is as follows:

[0092] S210, acquiring daytime point light data, nighttime point light data, parallel light indirect light data in three directions, and skylight indirect light data.

[0093] S220, baking the daytime point light data and the nighttime point light data respectively to obtain a first color value and a first intensity value corresponding to the daytime point light data, and a second color value, a second intensity value, and a point light direction corresponding to the nighttime point light data.

[0094] S230 , respectively bake the parallel light indirect light data in three directions to obtain the parallel light intensity value corresponding to the parallel light indirect light data in each direction.

[0095] S240, baking the skylight indirect light data to obtain the skylight intensity value, the skylight shielding direction, and the skylight shielding intensity value.

[0096] S250, storing the first color value, the first intensity value, the second color value, the second intensity value, the point light direction, the parallel light intensity value corresponding to the parallel light indirect light data in three directions, and the skylight intensity value as a first light map.

[0097] S260: Store the skylight shading direction and the skylight shading intensity value as a second light map.

[0098] S270 , rendering the picture according to the first light map and the second light map.

[0099] Before performing lighting processing, we need to clarify the data we need to bake, which are daytime point light data, nighttime point light data, parallel light indirect light data in three directions, and skylight indirect light data.

[0100] Among them, the parallel light indirect light data in three directions respectively represent the parallel light indirect light at 8 am, 12 noon and 16 pm.

[0101] As can be seen from the above, in order to bake the above data, a total of 6 baking times are required. In specific implementation, the total number of baking times can be set to 6 in advance, and then the baking parameters for each round of baking can be set. As for the results of each round of baking, the storage information of the result of each round of baking can also be configured in advance to realize the storage of the baking data obtained by each baking, for example, in which part of the map the baked data is stored, whether it is the color value, the direction value, or the gray value, etc., and in which channel it is stored.

[0102] The following will explain each round of baking in detail. If the baking order is set to: daytime point light data, nighttime point light data, 8-point parallel light indirect light data, 12-point parallel light indirect light data, 16-point parallel light indirect light data, skylight indirect light data.

[0103] 1. After baking the daytime point light data, the first color value and the first intensity value may be stored in a channel corresponding to an RGBA in the first light map.

[0104] 2. After baking the night point light data, the obtained second color value and second intensity value can be stored in a channel corresponding to one RGBA in the first light map, and the point light direction can be stored in a channel corresponding to another RGBA.

[0105] 3. When baking the 8-point parallel light indirect light data, the 12-point parallel light indirect light data, and the 18-point parallel light indirect light data, you can bake the information associated with the parallel light, close irrelevant content, and convert the baking results into grayscale information of the intensity of the parallel light associated with the baking at that time. Share the daytime indirect light information at night. Specifically, turn on the parallel light for projected self-luminescence and the point light representing indirect light to obtain the corresponding baking results, convert the obtained parallel light color value into intensity, so that after three bakings, you can get three parallel light intensity values. Store these three parallel light intensity values ​​in three channels in an RGBA of the first light map.

[0106] 4. When baking the skylight indirect light data, you can bake the information associated with the skylight, close irrelevant content, and convert the baking results into grayscale information of the intensity of the skylight associated with the baking at that time. Since the skylight shading direction does not change over time, there is no need to bake multiple times. The direction of the indirect light is obtained from the skylight shading direction. Specifically, turn on the skylight, standardize the skylight intensity and set the environment to pure white to obtain the corresponding baking result, and convert the obtained skylight color value into a skylight intensity value. The skylight intensity value is stored in one channel in an RGBA. That is to say, after baking the parallel light indirect light and the skylight indirect light, four intensity values ​​can be obtained. These four intensity values ​​can be stored in the corresponding channel of one RGBA in the first light map.

[0107] When baking skylight, the game engine can automatically generate a skylight occlusion data, that is, the skylight occlusion direction and skylight occlusion intensity can be obtained. The skylight occlusion direction and skylight occlusion intensity are stored in a channel corresponding to 1 RGBA of the second light map.

[0108] Therefore, the first light map and the second light map can be obtained by baking, so that the picture can be rendered according to the first light map and the second light map later.

[0109] In some embodiments, when rendering the picture, the parallel light color value and the skylight color value at the current moment can be obtained in real time. Since there are parallel light intensity values ​​corresponding to three hours, the parallel light intensity value corresponding to the three hours can be interpolated and calculated to obtain the parallel light intensity value corresponding to the current moment. As mentioned above, the parallel light indirect light of the three hours of 8 o'clock, 12 o'clock, and 16 o'clock are baked respectively. When realizing the day and night transformation, these data can be recycled. For example, one cycle is from 6 am to 18 o'clock in the evening, and another cycle is from 18 o'clock in the evening to 6 o'clock the next day. The usage rule with time can be that 8 o'clock is exactly the first copy, 12 o'clock is the second copy, and 16 o'clock is the third copy. At 20 o'clock in the evening, it changes back to the first copy, 24 o'clock is the second copy, 4 o'clock the next day is the third copy, and it changes back to the first copy at 8 o'clock the next day.

[0110] By multiplying the parallel light intensity value corresponding to the current moment with the parallel light color value at the current moment, the parallel light indirect light at the current moment can be restored. Figure 6 , which shows a schematic diagram of the rendering result obtained based on the indirect light information of parallel light.

[0111] Similarly, multiplying the skylight intensity value obtained from the first lightmap with the current skylight color value corresponding to the current moment can restore the skylight indirect lighting effect corresponding to the current moment. Figure 7 , which shows a schematic diagram of the rendering results obtained based on the indirect light information of the skylight.

[0112] The intensity of the point light during the day, that is, the first intensity value, is used as a mask to calculate the switching logic of the point light during the day and at night. The direction of the point light is an indispensable part of describing the point light information, and is used to calculate the illumination range and highlight of the point light. Among them, the direction of the light during the day is mainly based on skylight, so the highlight simulation is mainly calculated based on the skylight shading direction in the second light map.

[0113] The intensity of the point light during the day can be used as a mask to calculate the logic of the point light switch during the day and at night. The lighting during the day is mainly based on skylight, so the highlight simulation is mainly calculated based on the skylight occlusion direction in the second light map. At night, the point light direction is mainly used, and the strongest comparison length is taken; skylight occlusion is used to improve the light leakage phenomenon indoors, such as the bottom of the eaves, corners, etc.

[0114] Finally, the calculated direct and indirect light parts of point light, sky light, and parallel light are added together to obtain the final lighting information. Rendering based on this lighting information can achieve the day and night change effect in the game scene.

[0115] For ease of use, the corresponding editing tools are provided. Users can set the parameters of the keyframes through the editing tools to restore the real-time lighting effects corresponding to the current moment. These parameters may include: overall brightness, overall contrast, skylight color, height fog density, height fog attenuation, etc. And based on the idea of ​​splitting, debugging tools are provided. Users can split the final picture through the debugging tools to quickly locate the problem. Specifically, it can be split into pictures with only parallel light indirect light, split into pictures with only skylight direct light, etc.

[0116] As can be seen from the above, the embodiment of the present application bakes point light, parallel light, and sky light respectively to obtain first lighting information and second lighting information, and generates a lighting map based on the first lighting information and the second lighting information, so that the image can be rendered based on the lighting map later. The elements that change with time during the day and night change are separated and baked separately, so that it is convenient to perform real-time calculations based on the corresponding baking results to restore a more realistic day and night change effect. In addition, using the parallel light indirect light information of 3 hours, when rendering the picture, the accurate parallel light indirect light information corresponding to each hour can be obtained by interpolation, thereby improving the effect of day and night change and presenting a more realistic picture.
