[0032] Before describing the embodiments of the present disclosure in detail, the relevant terms involved in the present disclosure are first explained.

[0033] 1. Full-scale environment / full-scale scene

[0034] A full-scale scene is a scene displayed (or provided) when the client of an application (such as an educational application) runs on a terminal. It is a virtual scene, which refers to an environment created for virtual objects (i.e., characters in the scene) to carry out activities (such as education and learning). For example, it can be a virtual classroom, a virtual teaching scene, etc. The virtual scene can be a scene that simulates the real world, or it can also be a fictional scene, or it can be a semi-real and semi-fictional scene.

[0035] 2. Camera

[0036] The camera refers to the camera in the direction of the student's perspective in the real scene. The camera follows the characters in the real scene. One character corresponds to one camera. Only through the camera can the content in the real scene be presented to the user.

[0037] 3. Characters

[0038] The character is a virtual object in a real scene. It should be noted that the character described in the embodiments of the present disclosure mainly refers to the role of the current user in the real scene (i.e., the protagonist), and the current user is the user of the electronic device that executes the method for simulating a solar eclipse in a real scene provided by the present disclosure.

[0039] 4. Skybox

[0040] In modern computer games, skybox is a common method to fill the background. The so-called skybox is actually a cube unfolded, and then the corresponding textures are pasted on the six faces. The content of the texture can be a texture simulating real weather, the properties of objects in the scene such as houses, etc.

[0041] 5. Unity

[0042] Unity is a real-time 3D interactive content creation and operation platform. All creators, including game development, art, architecture, automotive design, film and television, use Unity to turn their creativity into reality.

[0043] 6. Shader

[0044] Shader is used to implement image rendering. It is an editable program that replaces the fixed rendering pipeline. It can implement related calculations in 3D graphics. Due to its editability, it can achieve a variety of image effects without being restricted by the fixed rendering pipeline of the graphics card.

[0045] 7. Tiling And Offset

[0046] Tiling represents the scaling factor of the UV coordinates, and Offset represents the starting position of the UV coordinates. Tiling and Offset are used to tile and offset the input UV values, which are usually used for detail maps and scrolling textures over time.

[0047] 8. Ellipse

[0048] Ellipse generates an ellipse shape based on the input UVs with the size specified by the input Width and Height, where the center of the ellipse is the center of the bounding rectangle. The generated shape can be offset or tiled by connecting a Tiling And Offset node.

[0049] At present, online teaching is widely used in the field of education. With the development of the real scene, the real classroom based on the real scene for online teaching has gradually become the focus of research and application because it simulates the real classroom environment.

[0050] In the online education scenario, in the relevant technology, when the instructor needs to explain the solar eclipse phenomenon, the relative displacement of the two spheres is mainly used to simulate the moon blocking the light from the sun to the earth, and the light and dark effects of the entire environment when the solar eclipse occurs are simulated by changing the lighting of the full-scene and the color of the sky box. However, when simulating the solar eclipse phenomenon in the above way, since the displacement of the sphere needs to be synchronized with the change of the light color, and needs to be observed at a fixed point, in order to achieve the full-real effect, a high frame rate refresh image is required to avoid mistakes, which consumes more device performance, resulting in high performance requirements for the device to simulate the solar eclipse phenomenon. In the mobile era, performance is one of the key factors affecting user growth and experience. If the performance of the device is poor, the mistakes will affect the simulation effect of the solar eclipse phenomenon.

[0051] In view of the above problems, the present invention provides a method for simulating the solar eclipse phenomenon in a full-scale scene. By adding a mask layer to the camera, the transparency of the mask layer is adjusted according to the overlap between the moon image and the sun image during the simulation of the solar eclipse phenomenon, so as to achieve the purpose of simulating the light and dark changes of the scene during the solar eclipse phenomenon by adjusting the transparency of the mask layer, and vividly and vividly display the solar eclipse phenomenon. In addition, in this scheme, the change of the environment in the full-scale scene is realized only by changing the transparency of the mask layer, and the requirements for device performance are low, which reduces the dependence on device performance, and also effectively avoids the occurrence of the gang phenomenon, thereby improving the simulation effect of the solar eclipse phenomenon. This scheme uses Unity's shader (Shader) to realize the change of the displacement and occlusion of the moon image, and then adds a black picture as a mask layer in front of the camera. By adjusting the transparency of the mask layer, the light and dark changes seen by the human eye when the solar eclipse occurs are completely simulated, so that students can easily understand the knowledge points of the solar eclipse phenomenon in a vivid and vivid way, and students can immersively experience the solar eclipse phenomenon in real life. Since this solution does not change the properties of the lighting, skybox and objects in the full-scale scene, it only adds a mask layer to the camera and adjusts the transparency of the mask layer to achieve the light and dark changes of the environment in the full-scale scene, thereby achieving the light and dark changes of the scene in the solar eclipse phenomenon. Therefore, the performance requirements of the device are not high. Therefore, the performance of the present invention on mobile devices will be greatly improved, and it can be adapted to more low-end models.

[0052] Figure 1 A flowchart of a method for simulating a solar eclipse phenomenon in a full-scale scene according to an exemplary embodiment of the present disclosure is shown. The method can be executed by a device for simulating a solar eclipse phenomenon in a full-scale scene, wherein the device can be implemented using software and / or hardware and can generally be integrated into electronic devices, such as mobile phones and tablet computers.

[0053] like Figure 1 As shown, the method for simulating the solar eclipse phenomenon in the real scene may include the following steps:

[0054] Step 101, in the process of simulating a solar eclipse phenomenon in a real scene, obtaining the degree of overlap between the moon image and the sun image.

[0055] The moon image may be a black circular image, and the moon image may be input, or may be generated based on an input sun image using a preset program, and the present disclosure does not impose any limitation on this.

[0056] In the disclosed embodiment, in a full-real scene, a moon image and a sun image can be used to simulate the solar eclipse process in the full-real scene by setting the moon image to move toward the sun image. When the moon image moves to the point where it begins to overlap with the sun image, the part of the sun image that overlaps with the moon image is covered by the moon image, and a solar eclipse occurs. As the degree of overlap between the moon image and the sun image increases, the illumination of the entire scene in the full-real scene becomes lower and lower. When the outline of the moon in the moon image completely overlaps with the outline of the sun in the sun image, it can be determined that a total solar eclipse occurs at this time, and the illumination of the entire environment in the full-real scene reaches the lowest. After that, as the moon image continues to move, the degree of solar eclipse gradually decreases, that is, the degree of overlap between the moon image and the sun image gradually decreases, and the illumination of the entire scene in the full-real scene begins to gradually increase. Therefore, in the disclosed embodiment, in the process of simulating the solar eclipse phenomenon, the degree of overlap between the moon image and the sun image can be obtained to simulate the change in ambient brightness in the full-real scene based on the degree of overlap.

[0057] For example, the degree of overlap between the moon image and the sun image can be characterized by the area of ​​the overlapping portion between the two. The overlapping area of ​​the two circles can be calculated by using the currently commonly used method of calculating the intersection area of ​​two circles. When implementing, it can be implemented by writing a program to calculate the intersection area of ​​two circles. When the area of ​​the overlapping portion is used to characterize the degree of overlap, the area of ​​the overlapping portion can be used as the degree of overlap, or the ratio of the area of ​​the overlapping portion to the area of ​​the circle in the sun image (or moon image) can be used as the degree of overlap.

[0058] For example, the degree of overlap between the moon image and the sun image can be characterized by the overlap length in the moving direction between the two. When calculating the overlap length, the radius of the moon image and the sun image, the center position of the circle on the moon image, and the center position of the circle on the sun image can be combined for calculation. When the overlap length is used to characterize the degree of overlap, the overlap length can be used as the degree of overlap, or the ratio between the overlap length and the diameter of the circle in the sun image (or moon image) can be used as the degree of overlap.

[0059] Step 102: Determine the target environment brightness corresponding to the overlap degree according to the overlap degree.

[0060] In the disclosed embodiment, after the degree of overlap between the moon image and the sun image is determined, the corresponding ambient brightness, ie, the target ambient brightness, may be determined according to the degree of overlap.

[0061] It can be understood that the more overlap there is between the moon image and the sun image, that is, the greater the degree of overlap, the greater the degree of solar eclipse phenomenon, and accordingly, the ambient brightness in the entire scene will become darker and darker. Therefore, in the embodiment of the present disclosure, the target ambient brightness is negatively correlated with the degree of overlap. In other words, the greater the degree of overlap, the smaller the corresponding target ambient brightness; the smaller the degree of overlap, the greater the corresponding target ambient brightness.

[0062] Exemplarily, taking the overlapping area as an example to characterize the degree of overlap between the moon image and the sun image, a mapping relationship table between different degrees of overlap and corresponding ambient brightness can be pre-set, and the mapping relationship table can be stored in the local memory. Thus, when determining the target ambient brightness corresponding to the degree of overlap, the mapping relationship table can be queried to find the target ambient brightness corresponding to the acquired degree of overlap. Among them, the value range of ambient brightness can be defined as 0 to 100 (including 0 and 100). When the value of ambient brightness is 100, it indicates that no solar eclipse has occurred or the solar eclipse has been completed. When the value of ambient brightness is 0, it indicates that a total solar eclipse has occurred.

[0063] Exemplarily, taking the ratio of the overlapping length to the diameter of a circle in the sun image (or moon image) as the degree of overlap, the ambient brightness when no solar eclipse occurs can be regarded as 1 (i.e. 100%), and the difference between 1 and the degree of overlap can be taken as the corresponding target ambient brightness.

[0064] Step 103, adjusting the transparency of the mask layer of the camera in the true scene according to the target environment brightness, so as to simulate the brightness change of the scene during the solar eclipse phenomenon.

[0065] The mask layer of the camera may be a black image added in front of the camera, and the black image may be a two-dimensional plane image.

[0066] In the disclosed embodiment, after determining the target environment brightness corresponding to the overlap degree, the transparency of the mask layer of the camera in the true scene can be adjusted according to the determined target environment brightness, thereby achieving the purpose of simulating the brightness changes of the scene during the solar eclipse phenomenon.

[0067] Exemplarily, assuming that the determined target environment brightness is a value between 0 and 100 in the above example, the transparency of the camera's mask layer can be adjusted according to the value. For example, when the transparency of the mask layer is the lowest (i.e., opaque, with a transparency of 0%), the environment brightness of the full-scene is the darkest. If the determined target environment brightness is 60, the transparency of the mask layer can be adjusted to 60%; if the determined target environment brightness is 100, the transparency of the mask layer is adjusted to the highest (i.e., fully transparent, with a transparency of 100%).

[0068] For example, assuming that the ambient brightness when there is no solar eclipse is regarded as 1 (i.e., 100%), and the difference between 1 and the degree of overlap is taken as the corresponding target ambient brightness, when adjusting the transparency of the mask layer of the camera according to the target ambient brightness, the transparency of the mask layer can be adjusted according to the product of the target ambient brightness and 100%. For example, if the determined target ambient brightness is 0.4, the transparency of the mask layer is adjusted to 40%.

[0069] It can be seen that in the embodiment of the present disclosure, only by adjusting the transparency of the mask layer of the camera, the brightness and darkness changes of the lighting in the entire scene corresponding to the changes in the degree of the solar eclipse phenomenon can be accurately simulated, thereby realizing the solar eclipse phenomenon in a true scene.

[0070] The method for simulating a solar eclipse phenomenon in a full-scale scene of the disclosed embodiment obtains the degree of overlap between the moon image and the sun image during the process of simulating the solar eclipse phenomenon in the full-scale scene, and determines the target environment brightness corresponding to the degree of overlap according to the degree of overlap, and then adjusts the transparency of the mask layer of the camera in the full-scale scene according to the target environment brightness, so as to simulate the brightness change of the scene during the solar eclipse phenomenon. The scheme disclosed in the present invention is adopted, by adding a mask layer to the camera, and adjusting the transparency of the mask layer according to the degree of overlap between the moon image and the sun image during the process of simulating the solar eclipse phenomenon, so as to achieve the purpose of simulating the brightness change of the scene during the solar eclipse phenomenon by adjusting the transparency of the mask layer, and vividly and figuratively displaying the solar eclipse phenomenon. Moreover, in the scheme, the change of the environment in the full-scale scene is achieved only by changing the transparency of the mask layer, and the requirements for the performance of the device are relatively low, and the dependence on the performance of the device is reduced. At the same time, the occurrence of the gang phenomenon is effectively avoided, and the simulation effect of the solar eclipse phenomenon is improved.

[0071] In an optional embodiment of the present disclosure, the lunar image used to simulate the solar eclipse phenomenon can be generated based on the input solar image. In this case, the method for simulating the solar eclipse phenomenon in a full-scale scene of the present disclosure may also include the following steps: obtaining preset initial position coordinates and the radius of the sun in the solar image; generating a black circular image based on the initial position coordinates and the radius; and using the black circular image as the lunar image.

[0072] The initial position coordinates and the radius of the sun in the solar image may be pre-set in the program, and the initial position coordinates are used to characterize the initial position of the moon in the generated lunar image.

[0073] In the disclosed embodiment, based on the preset initial position coordinates and the radius of the sun in the solar image, a black circular image can be generated, and the black circular image is used as the lunar image to complete the simulation of the solar eclipse phenomenon together with the solar image. When generating the black circular image, the initial position coordinates are used as the center of the circle, and the radius of the sun in the solar image is used as the radius to generate the black circular image, thereby obtaining the lunar image. The size of the lunar image is consistent with the size of the solar image, which is conducive to improving the simulation effect of the solar eclipse phenomenon.

[0074] For example, when a moon image is generated by a program, the generation of the moon image can be achieved by linking Tiling AndOffset and Ellipse functions in the program.

[0075] In an optional embodiment of the present disclosure, Figure 2 As shown, based on the above-mentioned embodiment, obtaining the degree of overlap between the moon image and the sun image may include the following steps:

[0076] Step 201, determining the moving distance of the moon image according to a preset moving step length and the current moving times.

[0077] The moving step length can be pre-set by a program, and the number of moves can be counted by a counter, the initial value of the counter is 0, and each time the moon image moves, the count value of the counter is accumulated by 1, so that the product of the moving step length and the number of moves represents the moving distance of the moon image. When the moon image moves, it can move according to a preset moving frequency.

[0078] Step 202: Determine the current position coordinates of the moon image according to the initial position coordinates and the moving distance.

[0079] In the disclosed embodiment, after the moving distance of the moon image is determined, the current position coordinates of the moon image can be determined based on the above initial position coordinates and the determined moving distance.

[0080] The current position coordinates refer to the coordinates of the position where the center of the circle representing the moon in the moon image is located.

[0081] It can be understood that when the lunar image moves in the horizontal direction (x direction), the x-direction coordinate of the center of the circle representing the moon changes, and the y-direction (vertical direction) coordinate remains unchanged. Therefore, in the embodiment of the present disclosure, the x-direction coordinate value in the current position coordinate can be added to the moving distance, and the coordinates in other directions remain unchanged, that is, the current position coordinates of the lunar image are obtained.

[0082] In an optional embodiment of the present disclosure, if the moving direction of the lunar image when moving toward the solar image is not horizontal, the moving direction of the lunar image can be calculated based on the initial position coordinates and the current position coordinates of the solar image (i.e., the position coordinates corresponding to the center of the circle representing the sun in the solar image), and then the current position coordinates of the lunar image can be calculated based on the initial position coordinates, the moving distance and the moving direction.

[0083] Step 203: Determine the relative distance between the moon image and the sun image based on the current position coordinates of the moon image and the current position coordinates of the sun image.

[0084] Among them, the current position coordinates of the sun image can be preset through the program.

[0085] In the disclosed embodiment, based on the current position coordinates of the moon image and the current position coordinates of the sun image, the distance between the moon image and the sun image, that is, the relative distance, can be calculated using the distance calculation formula between the two points.

[0086] Step 204: determining the overlap length between the moon image and the sun image based on the relative distance and the radius.

[0087] In the disclosed embodiment, based on the determined relative distance between the lunar image and the solar image, and the radius of the sun in the solar image, the maximum length of the overlapping portion in the moving direction between the lunar image and the solar image, referred to as the overlapping length, can be determined.

[0088] Exemplarily, when calculating the overlapping length, the result of (relative distance - 2*radius) can be expressed as the overlapping length. At this time, when the obtained difference is less than 0, it indicates that there is an overlap between the moon image and the sun image, that is, a solar eclipse occurs.

[0089] Exemplarily, when calculating the overlapping length, the result of (2*radius-relative distance) can be expressed as the overlapping length. At this time, when the obtained difference is greater than 0, it indicates that there is an overlap between the moon image and the sun image, that is, a solar eclipse occurs.

[0090] Figure 3 FIG. 1 is a schematic diagram showing the positional relationship between the moon image and the sun image in an exemplary embodiment of the present disclosure. Figure 3 Of the two circles shown, the left one represents the moon image, and the position of the center of the circle is the current position of the moon image. The right one represents the sun image, and the position of the center of the circle is the current position of the sun image. Figure 3As shown, there is a partial overlap between the solar image and the lunar image. The distance between point N on the lunar image and point M on the solar image, that is, the length of line segment MN, represents the overlapping length.

[0091] Step 205: Determine the overlap degree according to the overlap length.

[0092] In the embodiment of the present disclosure, after the overlapping length between the moon image and the sun image is determined, the overlapping degree between the moon image and the sun image can be determined according to the overlapping length.

[0093] Exemplarily, assuming that the result of (relative distance - 2*radius) is expressed as the overlapping length, when it is determined that the result of (relative distance - 2*radius) is less than 0, the absolute value of the obtained result (i.e., the overlapping length) is determined as the degree of overlap between the lunar image and the solar image; when it is determined that the result of (relative distance - 2*radius) is not less than 0, 0 is determined as the degree of overlap between the lunar image and the solar image.

[0094] Exemplarily, assuming that the overlapping length is twice the radius minus the difference of the relative distance, that is, the result of (2*radius-relative distance) is expressed as the overlapping length, then when it is determined that the overlapping length is greater than 0, the ratio between the overlapping length and twice the radius is determined as the degree of overlap, that is, the degree of overlap = overlapping length / (2*radius); when it is determined that the overlapping length is not greater than 0, 0 is determined as the degree of overlap between the lunar image and the solar image.

[0095] The method for simulating a solar eclipse phenomenon in a true-to-life scenario in an embodiment of the present disclosure determines the moving distance of the lunar image according to a preset moving step and the current number of movements, and determines the current position coordinates of the lunar image according to the initial position coordinates and the moving distance, and then determines the relative distance between the lunar image and the solar image based on the current position coordinates of the lunar image and the current position coordinates of the solar image, and determines the overlapping length between the lunar image and the solar image based on the relative distance and the radius, and then determines the degree of overlap between the lunar image and the solar image according to the overlapping length. Thus, a method for accurately determining the degree of overlap between the lunar image and the solar image is provided, which provides conditions for accurately simulating a solar eclipse phenomenon.

[0096] In a full-scale scene, the character is sometimes still and sometimes moving. When the character moves, the direction of the camera following the character changes accordingly, so as to switch the presentation content in the full-scale scene following the movement of the character, thereby improving the user's immersive experience. When the character moves, if the sun image still maintains its original direction, the character may not be able to feel the better effect of the solar eclipse phenomenon. Therefore, in an optional implementation of the present disclosure, in order to improve the user experience, the direction of the camera can be obtained at a preset frequency, and then the direction of the sun image and the moon image can be adjusted according to the direction of the camera, so that the direction of the sun image and the moon image is facing the camera, so that the user can have a better experience.

[0097] It should be noted that in the embodiment of the present disclosure, when the lunar image is generated based on the solar image, only the direction of the solar image can be adjusted to face the camera. Since the lunar image is generated based on the solar image, adjusting the direction of the solar image is equivalent to adjusting the direction of the lunar image.

[0098] In an optional embodiment of the present disclosure, when obtaining the orientation of the camera, the position coordinates of the character in the real scene when facing the sun image (called the first position coordinates) and the position coordinates of the character's current position (called the second position coordinates) can be obtained first, and then the moving direction and angle of the character relative to the sun image are determined based on the first position coordinates, the second position coordinates and the current position coordinates of the sun image, and then the orientation of the camera is determined based on the moving direction and angle.

[0099] Figure 4 FIG. 1 shows a schematic diagram of the movement of a character in a real scene in an exemplary embodiment of the present disclosure. Figure 4 The circle shown in represents the sun image, the position coordinates corresponding to the center of the circle and the current position coordinates of the sun image, point A represents the first position coordinates of the character in the full-scale scene when it faces the sun image, and point B represents the second position coordinates of the character's current position. Figure 4 It can be seen from the positions of the midpoint A and the point B that the character moves to the right, that is, the moving direction is to the right. According to the first position coordinate, the second position coordinate and the current position coordinate of the sun image, the moving angle of the character can also be determined. Figure 4 The α in it represents the moving angle.

[0100] In the disclosed embodiment, the orientation of the camera can be determined according to the determined moving direction and moving angle of the character in the real scene. For example, if the determined moving direction is moving to the right and the moving angle is 30 degrees, the orientation of the camera can be determined to be offset 30 degrees to the right. Furthermore, when adjusting the orientation of the sun image and the moon image, the orientation of the sun image and the moon image can also be offset 30 degrees to the right, that is, rotated 30 degrees counterclockwise from the current orientation.

[0101] In practical applications, the directions of the sun image and the moon image can be refreshed at a preset frequency through a program so that they always face the camera.

[0102] In the disclosed embodiment, the orientation of the camera is obtained at a preset frequency, and the orientations of the sun image and the moon image are adjusted according to the orientation of the camera so that the sun image and the moon image face the camera. This ensures that the camera is always facing the sun image and the moon image, that is, the camera always captures the process of the solar eclipse phenomenon, allowing users to experience the solar eclipse phenomenon in an immersive way, thereby enhancing user experience.

[0103] In practical applications, a Shader file can be pre-written to simulate the occurrence of a solar eclipse. By importing a solar image, according to the outline of the solar image, the generation of the lunar image and the displacement of the moon over time are realized by linking the Tiling And Offset and Ellipse functions in the Shader file. The refresh range of the lunar displacement is set by linking Step and One Minus, and the relevant data is summarized by Add. The Sample Texture 2D node is used to expose the interface for easy reference to the solar image. After the Shader file is written, a new material ball can be created to reference the Shader file, and a new empty node can be created in the scene to reference the newly created material ball, and then the pre-prepared solar image can be referenced through the node, and the parameters such as the radius of the sun, the initial position coordinates of the lunar image, and the moving step length are set. In addition, a black two-dimensional picture is added to the full-scale scene as the mask layer of the camera, and the displacement of the lunar image and the transparency of the refreshed mask layer are synchronously changed according to the preset frequency. The transparency of the mask layer can be determined according to the degree of overlap between the lunar image and the solar image. When the moving distance of the moon image reaches the distance threshold, it indicates that a solar eclipse is complete. At this time, the Shader related parameters can be reset and the mask layer of the camera can be removed. The distance threshold can be preset, for example, the distance threshold is set to (the distance between the initial position coordinates and the current position coordinates of the sun image + 2*the radius of the sun in the sun image). The above scheme is adopted to achieve the purpose of simulating the solar eclipse phenomenon in the full-scale scene, and the change of the ambient brightness in the full-scale scene is realized by changing the transparency of the mask layer.
