[0058] Next, Figure 1 Taking the electronic device 1000 as an example of an implementation subject, various embodiments of the data processing method of the virtual scene are explained.
[0059] <First Embodiment>
[0060] Figure 2A data processing method for a virtual scene according to some embodiments is shown, and the data processing method for a virtual scene may include the following steps S210 to S250:
[0061] Step S210 , in response to a display instruction of a virtual scene, determining a first scene area to be displayed in the virtual scene and a first active object in the first scene area.
[0062] In this embodiment, the display instruction may be triggered after the user starts the game or when the user switches to a virtual scene in the game.
[0063] In this embodiment, the virtual scene is composed of multiple scene modules, for example, the virtual scene is composed of 3×3 scene modules A, wherein the size of each scene module A is 1×1. The display instruction may indicate any one or more of the multiple scene modules, for example, the virtual scene is composed of 3×3 scene modules A, and the user's game interface may display three scene modules A located in the first row of the 3×3 scene modules A.
[0064] In this embodiment, the first scene area may be a scene area displayed to the user, and the first active object in the first scene area may be an object moved or newly created in the first scene area during the running of the game. The first active object may be, for example, a virtual character controlled by a user or computer AI, or a virtual building created.
[0065] Step S220, extracting a first tetrahedron matching the first scene area and first lighting data corresponding to the first tetrahedron from the preset scene lighting data; wherein the scene lighting data is used to characterize the lighting of the preset scene skylight and point light source in the virtual scene acting on the tetrahedron set in the virtual scene.
[0066] In this embodiment, when the scene area to be displayed in the virtual scene is the first scene area, the time node and the corresponding scene module currently corresponding to the first scene area are determined, and then the first tetrahedron set in the scene module corresponding to the first scene area is extracted from the tetrahedron in the virtual scene. The first tetrahedron is also composed of multiple probes, and the illumination data of each probe on the first tetrahedron is the first illumination data corresponding to the first tetrahedron.
[0067] In some embodiments, in order to improve the quality of lighting effects of prefabs in the virtual scene, the first tetrahedron is obtained by tetrahedralizing the probe group surrounding the prefabs in the first scene area after global illumination baking and point light baking.
[0068] In this embodiment, a tetrahedron is provided in the virtual scene, and the tetrahedron is composed of a plurality of probes that bake the scene skylight and point light sources. Among them, for the setting of scene illumination data, first, the probe (Probe) surrounds the prefab (Prefab) in the virtual scene and forms a probe group (Probe Group), and the scene skylight preset in the virtual scene is baked onto the probe group, and then the probe group baked with global illumination is obtained through the GPU Baker technology, and then the point light source is baked onto the probe group, and the probe group baked with the point light source is tetrahedralized to obtain the tetrahedron in the virtual scene, and the illumination data of each probe on the tetrahedron in the virtual scene is the scene illumination data. Among them, the prefab can be a virtual character, building or decoration set in the virtual scene during the construction of the virtual scene.
[0069] Step S230: determining, in the first tetrahedron, a second tetrahedron where the first active object is located.
[0070] In this embodiment, according to the position of the first active object in the first scene module, one or more second tetrahedrons where the first active object is located can be determined in the first tetrahedron.
[0071] Step S240: determining second illumination data of the first active object according to the positional relationship between the first active object and the second tetrahedron and the first illumination data.
[0072] In this embodiment, the positional relationship between the first active object and the second tetrahedron may be the distance deviation and direction deviation between the position of the first active object and the position of the first probe in the second tetrahedron in the virtual scene, or the distance deviation and direction deviation between the position of the first active object and the position where the center of gravity of the second tetrahedron is located. Furthermore, the first illumination data may be interpolated according to the distance deviation and the direction deviation to obtain the second illumination data of the first active object.
[0073] Step S250: displaying the lighting effect of the first scene area based on the first lighting data and the second lighting data.
[0074] In this embodiment, for the prefabricated body in the first scene area, the lighting effect can be performed using the first lighting data of the first tetrahedron, and for the first active object in the first scene area, the lighting effect can be performed using the second lighting data.
[0075] The data processing method for the virtual scene according to the first embodiment of the present invention solves the problem in the prior art that the lighting effects of the prefabricated body and the skylight need to be calculated in real time, which results in high memory consumption during the game operation. Based on this method, when the first scene area of the virtual scene needs to be displayed, the lighting effects of the prefabricated body in the virtual scene are preloaded before the game is run, and the lighting of the first active object in the virtual scene can be obtained through the lighting data of the prefabricated body, so as to effectively reduce the memory consumption during the game operation while ensuring that the first scene area has a better lighting effect.
[0076] <Second Embodiment>
[0077] In this embodiment, in order to achieve different lighting effects when the virtual scene changes from day to night, one or more point light sources can be set in the first scene area located at the first time node, and the point light sources can act on the prefabricated body and the first active object to enhance the visual effect of the first scene area.
[0078] In these embodiments, relative to the first embodiment, before step S220, the method further includes the following step S310:
[0079] Step S310, determining a first time node corresponding to a first scene area.
[0080] In this embodiment, when the display instruction of the virtual scene is triggered, the first time node corresponding to the first scene area is determined according to the game process. The game process here is, for example, the time recorded by the user's most recent archive in a single-player game or the current time set in the game in a multiplayer game. For example, taking a multiplayer game as an example, the time nodes are divided into "early" and "late", where "early" corresponds to 0 o'clock-12 o'clock and "late" corresponds to 12 o'clock-24 o'clock. Then, when the current time is 18 o'clock, the first time node corresponding to the first scene area is "late".
[0081] Based on this, step S220 may include the following step S2201:
[0082] Step S2201: extracting a first tetrahedron matching a first scene area and first illumination data corresponding to the first tetrahedron at a first time node from preset scene illumination data.
[0083] In this embodiment, when the scene area to be displayed in the virtual scene is the first scene area, the time node and the corresponding scene module currently corresponding to the first scene area are determined, and then the first tetrahedron set in the scene module corresponding to the first scene area is extracted from the tetrahedron in the virtual scene. The first tetrahedron is also composed of multiple probes, and the illumination data corresponding to each probe on the first tetrahedron at the first time node is the first illumination data corresponding to the first tetrahedron at the first time node.
[0084] <Third Embodiment>
[0085] In this embodiment, in order to further reduce memory consumption during game operation, the virtual scene may be composed of multiple scene modules, and the displayed first scene area may be at least a part of the multiple scene modules.
[0086] In these embodiments, relative to the first embodiment, step S210 may include the following step S410:
[0087] Step S410: Determine a first scene module associated with the display instruction from among multiple scene modules, and use it as a first scene area to be displayed in the virtual scene.
[0088] In this embodiment, the multiple scene modules are scene module C1-scene module C9, and the first scene module associated with the display instruction is scene module C1-scene module C2. Then, the first scene area to be displayed is scene module C1-scene module C2.
[0089] <Fourth Embodiment>
[0090] In this embodiment, in order to determine the second illumination data of the active object, the second illumination data of the first active object may be interpolated and calculated using the positional relationship between the first probe of the second tetrahedron and the first active object and the fourth illumination data of the first probe.
[0091] In these embodiments, relative to the first embodiment, step S240 may include the following steps S510 and S520:
[0092] Step S510 : determining a first probe surrounding the first moving object in the second tetrahedron and a relative distance between the first probe and the first moving object according to the positional relationship between the first moving object and the second tetrahedron.
[0093] Step S520: interpolate the fourth illumination data of the first probe according to the relative distance to obtain second illumination data of the first active object; wherein the fourth illumination data is illumination data corresponding to the first probe in the first illumination data.
[0094] In some examples, a point P1 of the first active object has coordinates (2, 0), a first probe L1 in the second tetrahedron has coordinates (1, 0) and the corresponding first illumination data value is 10, a first probe L2 in the second tetrahedron has coordinates (3, 0) and the corresponding first illumination data value is 20, then the value of the second illumination data of a point P1 of the first active object is 15. The value here only indicates that the second illumination data is obtained by interpolation of the first illumination data, and does not represent actual illumination data, such as irradiance.
[0095] <Fifth Embodiment>
[0096] In this embodiment, in order to save overhead during the running of the game, when the user switches from the first scene area to the second scene area of the virtual scene, the second scene area has a lighting effect, the second scene module adjacent to the first scene module and the fifth lighting data corresponding to the third tetrahedron where the second scene module is located are determined, and the third lighting information is used to render the lighting effect of the second scene area.
[0097] In these embodiments, relative to the third embodiment, after step S250, the method further includes the following steps S610 to S640:
[0098] Step S610: determining a second scene module adjacent to the first scene module among the multiple scene modules.
[0099] In this embodiment, the adjacency between scene modules can be an adjacency relationship determined according to the position distribution of each scene module in the virtual scene. For example, the virtual scene includes scene module F1-scene module F9, and scene module F1-scene module F9 are arranged in sequence in a "nine-square grid". The scene modules adjacent to scene module F1 are scene module F2 and scene module F4, and the scene modules adjacent to scene module F5 are scene module F1-scene module F4 and scene module F6-scene module F9.
[0100] Step S620, extracting a third tetrahedron matching the second scene area and fifth illumination data corresponding to the third tetrahedron from the scene illumination data;
[0101] In this embodiment, the scene lighting data is lighting data of tetrahedrons in all scene modules of the virtual scene, that is, the scene lighting data also includes the third tetrahedron matched by the second scene area and the fifth lighting data corresponding to the third tetrahedron.
[0102] Step S630: in response to the first scene area moving to the second scene area, determining a third scene module in the second scene module that is associated with the second scene area.
[0103] In some examples, the virtual scene corresponds to scene module H1-scene module H3, the first scene area corresponds to scene module H2, the second scene area corresponds to scene module H3, and the fifth illumination data of the third tetrahedron in scene module H3 is selected from the scene illumination data.
[0104] Step S640: display the lighting effect of the second scene area based on the first lighting data, the second lighting data and the fifth lighting data of the third scene module.
[0105] In some examples, the second scene area may include part of the first scene area, the virtual scene corresponds to scene module H1-scene module H3, the first scene area corresponds to scene module H1 and scene module H2, and the second scene area corresponds to scene module H2 and scene module H3. Through the scene lighting data, the lighting effect of the skylight in the second scene area, the lighting effect of the prefabricated object in the scene module H2, the lighting effect of the first active object in the scene module H2, and the lighting effect of the prefabricated object in the scene module H3 can be rendered. When the first active object moves from the first scene area to the second scene area, the lighting effect of the first active object is re-rendered through the fifth lighting data of the third scene module.
[0106] <Sixth Embodiment>
[0107] In this embodiment, in order to facilitate users to view the entire virtual scene or view more scene areas at the same time, when the user views the third scene area in the virtual scene, the third scene area only displays the lighting effect of the skylight, and the lighting details of the first active object and prefabricated body in the third scene area can be omitted, effectively saving the cost of running the game.
[0108] In these embodiments, relative to the first embodiment, after step S250, the method further includes the following step S710:
[0109] Step S710, in response to the virtual scene expanding from displaying the first scene area to displaying the third scene area, based on the skylight data in the scene lighting data, display the lighting effect of the third scene area; wherein a portion of the third scene area is the first scene area.
[0110] In some examples, the virtual scene includes scene module F1-scene module F9, and scene module F1-scene module F9 are arranged in sequence in a "nine-square grid". The first scene area is scene area F1. When the user triggers the first scene area to expand to display the third scene area, the user's game interface switches from displaying scene area F1 to displaying scene area F1, scene area F2, scene area F4 and scene area F5. At this time, the skylight data about scene area F1, scene area F2, scene area F4 and scene area F5 in the scene lighting data can be extracted, and based on the skylight data, the lighting effects of scene area F1, scene area F2, scene area F4 and scene area F5 are displayed.
[0111] <Seventh Embodiment>
[0112] In this embodiment, in order to further improve the realism of the lighting effect of the first active object in the virtual scene, the lighting data of the second active object placed later in the first scene area is compared with the lighting data of the first tetrahedron where the prefabricated body is located, and the first active object is rendered by lighting data with stronger irradiance, thereby effectively improving the realism of the lighting effect of the virtual scene.
[0113] In these embodiments, relative to the first embodiment, before step S240, the method further includes the following step S810:
[0114] Step S810, obtaining a first bounding box of a second active object located behind the first scene area in which the first active object is located, and obtaining third illumination data of the first bounding box.
[0115] In this embodiment, the post-placed second active object may be a virtual character, virtual building, or virtual decoration, etc., that has been set in the first scene area by the user or computer AI before the display instruction of the virtual scene is triggered. After the second active object is set in the first scene area, a first bounding box surrounding the second active object may be set around the second active object, the first bounding box is composed of a plurality of probes, and when the positions of the plurality of probes of the first bounding box in the virtual scene are determined, the illumination data on the plurality of probes of the first bounding box may be determined based on the scene illumination data, i.e., the third illumination data of the first bounding box.
[0116] Based on this, step S240 may include the following steps S2401 and S2402:
[0117] Step S2401 : when the irradiance reflected by the third illumination data is greater than the irradiance reflected by the first illumination data, second illumination data of the first active object is determined according to the positional relationship between the first active object and the first bounding box and the third illumination data.
[0118] In this embodiment, the positional relationship between the first active object and the first bounding box may be the distance deviation and direction deviation between the first active object and each probe in the first bounding box, or the distance deviation and direction deviation between the first active object and the center of gravity of the first bounding box.
[0119] Step S2402: when the irradiance reflected by the third illumination data is less than or equal to the irradiance reflected by the first illumination data, second illumination data of the first active object is determined according to the positional relationship between the first active object and the second tetrahedron and the first illumination data.
[0120] In this embodiment, the irradiance reflected by the first illumination data may be the irradiance of the scene skylight and the point light source acting on the prefabricated body in the first scene area. The irradiance reflected by the third illumination data may be the irradiance of the scene skylight and the point light source acting on the second active object. Moreover, by using illumination data with a stronger irradiance, the authenticity of the illumination effect of the first active object can be effectively improved.
